Properties

diagnostics	Provides diagnostic information to an Outlook add-in. Contains the following members. `hostName` (string): A string that represents the name of the Office application. It should be one of the following values: `Outlook`, `newOutlookWindows`, `OutlookWebApp`, `OutlookIOS`, or `OutlookAndroid`. Note: The "Outlook" value is returned for Outlook on Windows (classic) and on Mac. `hostVersion` (string): A string that represents the version of either the Office application or the Exchange Server (e.g., "15.0.468.0"). If the mail add-in is running in Outlook on Windows (classic), on Mac, or on mobile devices, the `hostVersion` property returns the version of the Outlook client. In Outlook on the web and new Outlook on Windows, the property returns the version of the Exchange Server. `OWAView` (`MailboxEnums.OWAView` or string): An enum (or string literal) that represents the current view of Outlook on the web. If the application is not Outlook on the web, then accessing this property results in undefined. Outlook on the web has three views (`OneColumn` - displayed when the screen is narrow, `TwoColumns` - displayed when the screen is wider, and `ThreeColumns` - displayed when the screen is wide) that correspond to the width of the screen and the window, and the number of columns that can be displayed. More information is under Office.Diagnostics.
ewsUrl	Gets the URL of the Exchange Web Services (EWS) endpoint for this email account.
item	The mailbox item. Depending on the context in which the add-in opened, the item type may vary. If you want to see IntelliSense for only a specific type or mode, cast this item to one of the following: MessageCompose, MessageRead, AppointmentCompose, AppointmentRead Important: When calling `Office.context.mailbox.item` on a message, note that the Reading Pane in the Outlook client must be turned on. For guidance on how to configure the Reading Pane, see Use and configure the Reading Pane to preview messages. `item` can be null if your add-in supports pinning the task pane. For details on how to handle, see Implement a pinnable task pane in Outlook.
restUrl	Gets the URL of the REST endpoint for this email account.
userProfile	Information about the user associated with the mailbox. This includes their account type, display name, email address, and time zone. More information is under Office.UserProfile

Methods

addHandlerAsync(eventType, handler, options, callback)	Adds an event handler for a supported event. Note: Events are only available with task pane implementation. For supported events, refer to the Mailbox object model events section.
addHandlerAsync(eventType, handler, callback)	Adds an event handler for a supported event. Note: Events are only available with task pane implementation. For supported events, refer to the Mailbox object model events section.
convertToEwsId(id, restVersion)	Converts a supported ID into the Exchange Web Services (EWS) format.
convertToLocalClientTime(timeValue)	Gets a dictionary containing time information in local client time. The time zone used by the Outlook client varies by platform. Outlook on Windows (classic) and on Mac use the client computer time zone. Outlook on the web and new Outlook on Windows use the time zone set on the Exchange Admin Center (EAC). You should handle date and time values so that the values you display on the user interface are always consistent with the time zone that the user expects. In Outlook on Windows (classic) and on Mac, the `convertToLocalClientTime` method returns a dictionary object with the values set to the client computer time zone. In Outlook on the web and new Outlook on Windows, the `convertToLocalClientTime` method returns a dictionary object with the values set to the time zone specified in the EAC.
convertToRestId(id, restVersion)	Converts a supported ID into REST format.
convertToUtcClientTime(input)	Gets a `Date` object from a dictionary containing time information. The `convertToUtcClientTime` method converts a dictionary containing a local date and time to a `Date` object with the correct values for the local date and time.
displayAppointmentForm(itemId)	Displays an existing calendar appointment. The `displayAppointmentForm` method opens an existing calendar appointment in a new window on the desktop. In Outlook on Mac, you can use this method to display a single appointment that isn't part of a recurring series, or the master appointment of a recurring series. However, you can't display an instance of the series because you can't access the properties (including the item ID) of instances of a recurring series. In Outlook on the web and new Outlook on Windows, this method opens the specified form only if the body of the form is less than or equal to 32K characters. If the specified item identifier does not identify an existing appointment, a blank pane opens on the client computer or device, and no error message is returned.
displayMessageForm(itemId)	Displays an existing message. The `displayMessageForm` method opens an existing message in a new window on the desktop. In Outlook on the web and new Outlook on Windows, this method opens the specified form only if the body of the form is less than or equal to 32K characters. If the specified item identifier doesn't identify an existing message, no message will be displayed on the client computer, and no error message is returned.
displayNewAppointmentForm(parameters)	Displays a form for creating a new calendar appointment. The `displayNewAppointmentForm` method opens a form that enables the user to create a new appointment or meeting. If parameters are specified, the appointment form fields are automatically populated with the contents of the parameters. In Outlook on the web and new Outlook on Windows, this method always displays a form with an attendees field. If you don't specify any attendees as input arguments, the method displays a form with a Save button. If you have specified attendees, the form would include the attendees and a Send button. In Outlook on Windows (classic) and on Mac, if you specify any attendees or resources in the `requiredAttendees`, `optionalAttendees`, or `resources` parameter, this method displays a meeting form with a Send button. If you don't specify any recipients, this method displays an appointment form with a Save & Close button. If any of the parameters exceed the specified size limits, or if an unknown parameter name is specified, an exception is thrown.
displayNewMessageForm(parameters)	Displays a form for creating a new message. The `displayNewMessageForm` method opens a form that enables the user to create a new message. If parameters are specified, the message form fields are automatically populated with the contents of the parameters. If any of the parameters exceed the specified size limits, or if an unknown parameter name is specified, an exception is thrown.
getCallbackTokenAsync(options, callback)	Gets a string that contains a token used to call REST APIs or Exchange Web Services (EWS). The `getCallbackTokenAsync` method makes an asynchronous call to get an opaque token from the Exchange Server that hosts the user's mailbox. The lifetime of the callback token is 5 minutes. The token is returned as a string in the `asyncResult.value` property.
getCallbackTokenAsync(callback, userContext)	Gets a string that contains a token used to get an attachment or item from an Exchange Server. The `getCallbackTokenAsync` method makes an asynchronous call to get an opaque token from the Exchange Server that hosts the user's mailbox. The lifetime of the callback token is 5 minutes. The token is returned as a string in the `asyncResult.value` property.
getIsIdentityManaged()	Returns true if the current mailbox is managed by Microsoft Intune.
getIsOpenFromLocationAllowed(openLocation)	Returns true if an organization's Intune mobile application management (MAM) policy allows an add-in to access data from the specified location.
getIsSaveToLocationAllowed(saveLocation)	Returns true if an organization's Intune mobile application management (MAM) policy allows an add-in to save data to the specified location.
getUserIdentityTokenAsync(callback, userContext)	Gets a token identifying the user and the Office Add-in. The token is returned as a string in the `asyncResult.value` property.
makeEwsRequestAsync(data, callback, userContext)	Makes an asynchronous request to an Exchange Web Services (EWS) service on the Exchange server that hosts the user's mailbox. The `makeEwsRequestAsync` method sends an EWS request on behalf of the add-in to Exchange.
removeHandlerAsync(eventType, options, callback)	Removes the event handlers for a supported event type. Note: Events are only available with task pane implementation. For supported events, refer to the Mailbox object model events section.

ewsUrl: string;

Property Value

string

Remarks

[ API set: Mailbox 1.1 ]

Minimum permission level: read item

Applicable Outlook mode: Compose or Read

Important:

Your app must have the read item permission specified in its manifest to call the ewsUrl member in read mode.
In compose mode, you must call the saveAsync method before you can use the ewsUrl member. Your app must have read/write item permissions to call the saveAsync method.
This property isn't supported in Outlook on Android or on iOS. For more information on supported APIs in Outlook mobile, see Outlook JavaScript APIs supported in Outlook on mobile devices.
The ewsUrl value can be used by a remote service to make EWS calls to the user's mailbox. For example, you can create a remote service to get attachments from the selected item.

Examples

// Link to full sample: https://raw.githubusercontent.com/OfficeDev/office-js-snippets/prod/samples/outlook/85-tokens-and-service-calls/ids-and-urls.yaml

// Get the EWS URL and EWS item ID.
console.log("EWS URL: " + Office.context.mailbox.ewsUrl);
const ewsId = Office.context.mailbox.item.itemId;
console.log("EWS item ID: " + Office.context.mailbox.item.itemId);

// Convert the EWS item ID to a REST-formatted ID.
const restId = Office.context.mailbox.convertToRestId(ewsId, Office.MailboxEnums.RestVersion.v2_0);
console.log("REST item ID: " + restId);

// Convert the REST-formatted ID back to an EWS-formatted ID.
const ewsId2 = Office.context.mailbox.convertToEwsId(restId, Office.MailboxEnums.RestVersion.v2_0);
console.log("EWS ID (from REST ID): " + ewsId2);

restUrl: string;

Property Value

string

Remarks

[ API set: Mailbox 1.5 ]

Minimum permission level: read item

Applicable Outlook mode: Compose or Read

Important:

The Outlook REST v2.0 and beta endpoints are now deprecated. However, privately released and AppSource-hosted add-ins are able to use the REST service until extended support ends for Outlook 2019 on October 14, 2025. Traffic from these add-ins is automatically identified for exemption. This exemption also applies to new add-ins developed after March 31, 2024. Although add-ins are able to use the REST service until 2025, we highly encourage you to migrate your add-ins to use Microsoft Graph. For guidance, see Compare Microsoft Graph and Outlook REST API endpoints.
Your add-in must have the read item permission specified in its manifest to call the restUrl member in read mode.
In compose mode you must call the saveAsync method before you can use the restUrl member. Your add-in must have read/write item permissions to call the saveAsync method. However, in delegate or shared scenarios, you should instead use the targetRestUrl property of the SharedProperties object (introduced in requirement set 1.8). For more information, see the shared folders and shared mailbox article.

Examples

// Get the URL of the REST endpoint.
const restUrl = Office.context.mailbox.restUrl;
console.log(`REST API URL: ${restUrl}`);

userProfile

Information about the user associated with the mailbox. This includes their account type, display name, email address, and time zone.

More information is under Office.UserProfile

This is part of Microsoft's Secure Future Initiative, which gives organizations the tools needed to respond to the current threat landscape. Exchange user identity tokens will still work for Exchange on-premises. Nested app authentication is the recommended approach for tokens going forward. For more information, see our blog post and FAQ page.
This method isn't supported in Outlook on Android or on iOS. For more information on supported APIs in Outlook mobile, see Outlook JavaScript APIs supported in Outlook on mobile devices.
Item IDs retrieved via a REST API (such as Microsoft Graph) use a different format than the format used by EWS. The convertToEwsId method converts a REST-formatted ID into the proper format for EWS.

Examples

// Link to full sample: https://raw.githubusercontent.com/OfficeDev/office-js-snippets/prod/samples/outlook/85-tokens-and-service-calls/ids-and-urls.yaml

// Get the EWS URL and EWS item ID.
console.log("EWS URL: " + Office.context.mailbox.ewsUrl);
const ewsId = Office.context.mailbox.item.itemId;
console.log("EWS item ID: " + Office.context.mailbox.item.itemId);

// Convert the EWS item ID to a REST-formatted ID.
const restId = Office.context.mailbox.convertToRestId(ewsId, Office.MailboxEnums.RestVersion.v2_0);
console.log("REST item ID: " + restId);

// Convert the REST-formatted ID back to an EWS-formatted ID.
const ewsId2 = Office.context.mailbox.convertToEwsId(restId, Office.MailboxEnums.RestVersion.v2_0);
console.log("EWS ID (from REST ID): " + ewsId2);

convertToLocalClientTime(timeValue)

Gets a dictionary containing time information in local client time.

The time zone used by the Outlook client varies by platform. Outlook on Windows (classic) and on Mac use the client computer time zone. Outlook on the web and new Outlook on Windows use the time zone set on the Exchange Admin Center (EAC). You should handle date and time values so that the values you display on the user interface are always consistent with the time zone that the user expects.

In Outlook on Windows (classic) and on Mac, the convertToLocalClientTime method returns a dictionary object with the values set to the client computer time zone. In Outlook on the web and new Outlook on Windows, the convertToLocalClientTime method returns a dictionary object with the values set to the time zone specified in the EAC.

getCallbackTokenAsync(options, callback)

Gets a string that contains a token used to call REST APIs or Exchange Web Services (EWS).

The getCallbackTokenAsync method makes an asynchronous call to get an opaque token from the Exchange Server that hosts the user's mailbox. The lifetime of the callback token is 5 minutes.

The token is returned as a string in the asyncResult.value property.

getCallbackTokenAsync(options: Office.AsyncContextOptions & { isRest?: boolean }, callback: (asyncResult: Office.AsyncResult<string>) => void): void;

Parameters

options: Office.AsyncContextOptions & { isRest?: boolean }

An object literal that contains one or more of the following properties:- isRest: Determines if the token provided will be used for the Outlook REST APIs or Exchange Web Services. Default value is false. asyncContext: Any state data that is passed to the asynchronous method.

callback: (asyncResult: Office.AsyncResult<string>) => void

When the method completes, the function passed in the callback parameter is called with a single parameter of type Office.AsyncResult. The token is returned as a string in the asyncResult.value property. If there was an error, the asyncResult.error and asyncResult.diagnostics properties may provide additional information.

Returns

void

In October 2024, legacy Exchange user identity and callback tokens will be turned off by default for all Exchange Online tenants. This is part of Microsoft's Secure Future Initiative, which gives organizations the tools needed to respond to the current threat landscape. Exchange user identity tokens will still work for Exchange on-premises. Nested app authentication is the recommended approach for tokens going forward. For more information, see our blog post and FAQ page.
The Outlook REST v2.0 and beta endpoints are now deprecated. However, privately released and AppSource-hosted add-ins are able to use the REST service until extended support ends for Outlook 2019 on October 14, 2025. Traffic from these add-ins is automatically identified for exemption. This exemption also applies to new add-ins developed after March 31, 2024. Although add-ins are able to use the REST service until 2025, we highly encourage you to migrate your add-ins to use Microsoft Graph. For guidance, see Compare Microsoft Graph and Outlook REST API endpoints.
This method isn't supported if you load an add-in in an Outlook.com or Gmail mailbox.
This method is only supported in read mode in Outlook on Android and on iOS. For more information on supported APIs in Outlook mobile, see Outlook JavaScript APIs supported in Outlook on mobile devices.
EWS operations aren't supported in add-ins running in Outlook on iOS and on Android. A REST token is always returned in Outlook mobile clients even if options.isRest is set to false.
Calling the getCallbackTokenAsync method in read mode requires a minimum permission level of read item.
Calling the getCallbackTokenAsync method in compose mode requires you to have saved the item. The saveAsync method requires a minimum permission level of read/write item.
For guidance on delegate or shared scenarios, see the shared folders and shared mailbox article.

REST Tokens

When a REST token is requested (options.isRest = true), the resulting token won't work to authenticate EWS calls. The token will be limited in scope to read-only access to the current item and its attachments, unless the add-in has specified the read/write mailbox permission in its manifest. If the read/write mailbox permission is specified, the resulting token will grant read/write access to mail, calendar, and contacts, including the ability to send mail.

The add-in should use the restUrl property to determine the correct URL to use when making REST API calls.

This API works for the following scopes.

Mail.ReadWrite
Mail.Send
Calendars.ReadWrite
Contacts.ReadWrite

EWS Tokens

When an EWS token is requested (options.isRest = false), the resulting token won't work to authenticate REST API calls. The token will be limited in scope to accessing the current item.

The add-in should use the ewsUrl property to determine the correct URL to use when making EWS calls.

You can pass both the token and either an attachment identifier or item identifier to an external system. That system uses the token as a bearer authorization token to call the Exchange Web Services (EWS) GetAttachment operation or GetItem operation to return an attachment or item. For example, you can create a remote service to get attachments from the selected item.

Errors:

HTTPRequestFailure: The request has failed. Please look at the diagnostics object for the HTTP error code.
InternalServerError: The Exchange server returned an error. Please look at the diagnostics object for more information.
NetworkError: The user is no longer connected to the network. Please check your network connection and try again.

getCallbackTokenAsync(callback, userContext)

Gets a string that contains a token used to get an attachment or item from an Exchange Server.

The getCallbackTokenAsync method makes an asynchronous call to get an opaque token from the Exchange Server that hosts the user's mailbox. The lifetime of the callback token is 5 minutes.

The token is returned as a string in the asyncResult.value property.

getCallbackTokenAsync(callback: (asyncResult: Office.AsyncResult<string>) => void, userContext?: any): void;

Parameters

Exchange user identity tokens will still work for Exchange on-premises. Nested app authentication is the recommended approach for tokens going forward. For more information, see our blog post and FAQ page.
To enable the makeEwsRequestAsync method to make EWS requests, the server administrator must set OAuthAuthentication to true on the Client Access Server EWS directory .
Your add-in must have the read/write mailbox permission to use the makeEwsRequestAsync method. For information about using the read/write mailbox permission and the EWS operations that you can call with the makeEwsRequestAsync method, see Specify permissions for mail add-in access to the user's mailbox.
If your add-in needs to access Folder Associated Items or its XML request must specify UTF-8 encoding (\<?xml version="1.0" encoding="utf-8"?\>), it must use Microsoft Graph or REST APIs to access the user's mailbox instead.
This method isn't supported in Outlook on Android or on iOS. For more information on supported APIs in Outlook mobile, see Outlook JavaScript APIs supported in Outlook on mobile devices.
This method isn't supported when the add-in is loaded in a Gmail mailbox.
When you use the makeEwsRequestAsync method in add-ins that run in Outlook versions earlier than Version 15.0.4535.1004, you must set the encoding value to ISO-8859-1 (<?xml version="1.0" encoding="iso-8859-1"?>). To determine the version of an Outlook client, use the mailbox.diagnostics.hostVersion property. You don't need to set the encoding value when your add-in is running in Outlook on the web or new Outlook on Windows. To determine the Outlook client in which your add-in is running, use the mailbox.diagnostics.hostName property.
