string

Remarks

Minimum permission level: read item

Applicable Outlook mode: Message Read

Important:

The itemId property isn't available in compose mode. If an item identifier is required, the Office.context.mailbox.item.saveAsync method can be used to save the item to the store, which will return the item identifier in the asyncResult.value parameter in the callback function. If the item is already saved, you can call the Office.context.mailbox.item.getItemIdAsync method instead.
The item ID returned isn't identical to the Outlook Entry ID or the ID used by the Outlook REST API. Before making REST API calls using this value, it should be converted using Office.context.mailbox.convertToRestId.

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;
if (itemId === null || itemId == undefined) {
    Office.context.mailbox.item.saveAsync(function(result) {
        itemId = result.value;
    });
}

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.

getAttachmentContentAsync(attachmentId, options, callback)

Gets an attachment from a message or appointment and returns it as an AttachmentContent object.

The getAttachmentContentAsync method gets the attachment with the specified identifier from the item. As a best practice, you should get the attachment's identifier from an item.attachments call, then in the same session, use that identifier to retrieve the attachment. In Outlook on the web, on mobile devices, and in new Outlook on Windows, the attachment identifier is valid only within the same session. A session is over when the user closes the app, or if the user starts composing an inline form then subsequently pops out the form to continue in a separate window.

getAttachmentContentAsync(attachmentId: string, options: Office.AsyncContextOptions, callback?: (asyncResult: Office.AsyncResult<AttachmentContent>) => void): void;

Parameters

attachmentId: string

The identifier of the attachment you want to get.

options: Office.AsyncContextOptions

An object literal that contains one or more of the following properties:- asyncContext: Developers can provide any object they wish to access in the callback function.

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

Returns

void

Remarks

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.
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.

Examples

// Consider an add-in manifest has the following `Rule` element:
//<Rule xsi:type="RuleCollection" Mode="And">

//  </Rule>
//</Rule>

// The object returned from `getRegExMatches` would have two properties: `fruits` and `veggies`.
//{
//'fruits': ['apple','banana','Banana','coconut'],

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.
