dateTimeCreated

Gets the date and time that an item was created.

dateTimeModified

Gets the date and time that an item was last modified.

end

Gets the date and time that the appointment is to end.

The end property is a Date object expressed as a Coordinated Universal Time (UTC) date and time value. You can use the convertToLocalClientTime method to convert the end property value to the client's local date and time.

When you use the Time.setAsync method to set the end time, you should use the convertToUtcClientTime method to convert the local time on the client to UTC for the server.

itemClass

Gets the Exchange Web Services item class of the selected appointment.

Returns IPM.Appointment for non-recurring appointments and IPM.Appointment.Occurrence for recurring appointments.

itemId

Gets the Exchange Web Services (EWS) item identifier of the current item.

itemType

Gets the type of item that an instance represents.

The itemType property returns one of the ItemType enumeration values, indicating whether the item object instance is a message or an appointment.

location

Gets the location of an appointment.

The location property returns a string that contains the location of the appointment.

normalizedSubject

Gets the subject of an item, with all prefixes removed (including RE: and FWD:).

The normalizedSubject property gets the subject of the item, with any standard prefixes (such as RE: and FW:) that are added by email programs. To get the subject of the item with the prefixes intact, use the subject property.

notificationMessages

Gets the notification messages for an item.

optionalAttendees

Provides access to the optional attendees of an event. The type of object and level of access depend on the mode of the current item.

The optionalAttendees property returns an array that contains an EmailAddressDetails object for each optional attendee to the meeting. The maximum number of attendees returned varies per Outlook client.

  • Windows: 500 attendees

  • Android, classic Mac UI, iOS: 100 attendees

  • New Mac UI, web browser: No limit

organizer

Gets the meeting organizer's email properties.

recurrence

Gets the recurrence pattern of an appointment. Gets the recurrence pattern of a meeting request.

The recurrence property returns a Recurrence object for recurring appointments or meetings requests if an item is a series or an instance in a series. null is returned for single appointments and meeting requests of single appointments.

Note: Meeting requests have an itemClass value of IPM.Schedule.Meeting.Request.

Note: If the recurrence object is null, this indicates that the object is a single appointment or a meeting request of a single appointment and NOT a part of a series.

requiredAttendees

Provides access to the required attendees of an event. The type of object and level of access depend on the mode of the current item.

The requiredAttendees property returns an array that contains an EmailAddressDetails object for each required attendee to the meeting. The maximum number of attendees returned varies per Outlook client.

  • New Mac UI, web browser: No limit

seriesId

Gets the ID of the series that an instance belongs to.

In Outlook on the web, on Windows (new and classic), and on Mac, the seriesId returns the Exchange Web Services (EWS) ID of the parent (series) item that this item belongs to. However, on iOS and Android, the seriesId returns the REST ID of the parent item.

Note: The identifier returned by the seriesId property is the same as the Exchange Web Services item identifier. The seriesId property is not identical to the Outlook IDs used by the Outlook REST API. Before making REST API calls using this value, it should be converted using Office.context.mailbox.convertToRestId. For more details, see Use the Outlook REST APIs from an Outlook add-in.

The seriesId property returns null for items that do not have parent items such as single appointments, series items, or meeting requests and returns undefined for any other items that are not meeting requests.

start

Examples

// The following code checks for the presence of an item
// identifier. If the `itemId` property returns `null` or
// `undefined`, it saves the item to the store and gets the
// item identifier from the asynchronous result.
// **Important**: `saveAsync` was introduced with requirement set 1.3
// so you can't get the `itemId` in Compose mode in earlier sets.
let itemId = Office.context.mailbox.item.itemId;

displayReplyForm(formData)

Displays a reply form that includes only the sender of the selected message or the organizer of the selected appointment.

displayReplyForm(formData: string | ReplyFormData): void;

Parameters

formData

string | Office.ReplyFormData

A string that contains text and HTML and that represents the body of the reply form. The string is limited to 32 KB OR a ReplyFormData object that contains body or attachment data and a callback function.

Returns

void

Remarks

[ API set: Mailbox 1.1 ]

Minimum permission level: read item

Applicable Outlook mode: Appointment Attendee

Important:

  • In Outlook on the web and new Outlook on Windows, the reply form is displayed as a pop-out form in the 3-column view and a pop-up form in the 2-column or 1-column view.

  • If any of the string parameters exceed their limits, displayReplyForm throws an exception.

  • When attachments are specified in the formData.attachments parameter, Outlook attempts to download all attachments and attach them to the reply form. If any attachments fail to be added, an error is shown in the form UI. If this isn't possible, then no error message is thrown.

  • 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.

Important:

  • Entity-based contextual Outlook add-ins are now retired. However, regular expression rules are still supported. We recommend updating your contextual add-in to use regular expression rules as an alternative solution. For guidance on how to implement these rules, see Contextual Outlook add-ins.

  • This method is used with the activation rules feature for Outlook add-ins, which isn't supported by the unified manifest for Microsoft 365.

  • If you specify an ItemHasRegularExpressionMatch rule on the body property of an item, the regular expression should further filter the body and shouldn't attempt to return the entire body of the item. Using a regular expression such as .* to obtain the entire body of an item doesn't always return the expected results. Instead, use the Body.getAsync method to retrieve the entire body.

Examples

// Consider an add-in manifest has the following `Rule` element:

getRegExMatchesByName(name)

Returns string values in the selected item that match the named regular expression defined in an add-in only manifest file.

getRegExMatchesByName(name: string): string[];

Parameters

name

string

The name of the ItemHasRegularExpressionMatch rule element that defines the filter to match.

Returns

string[]

An array that contains the strings that match the regular expression defined in the ItemHasRegularExpressionMatch rule element in the add-in manifest file, with the specified RegExName element value.

loadCustomPropertiesAsync(callback, userContext)

Asynchronously loads custom properties for this add-in on the selected item.

Custom properties are stored as key-value pairs on a per-app, per-item basis. This method returns a CustomProperties object in the callback, which provides methods to access the custom properties specific to the current item and the current add-in. Custom properties aren't encrypted on the item, so this shouldn't be used as secure storage.

The custom properties are provided as a CustomProperties object in the asyncResult.value property. This object can be used to get, set, save, and remove custom properties from the mail item.

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

Parameters

callback

(asyncResult: Office.AsyncResult<Office.CustomProperties>) => void

When the method completes, the function passed in the callback parameter is called with a single parameter of type Office.AsyncResult.

userContext

any

Optional. Developers can provide any object they wish to access in the callback function. This object can be accessed by the asyncResult.asyncContext property in the callback function.

Returns

void

Remarks
