Examples

// This example gets the body of the item as plain text.
Office.context.mailbox.item.body.getAsync(
    "text",
    { asyncContext: "This is passed to the callback" },
    function callback(result) {
        // Do something with the result.
    });

// The following is an example of an object that is passed as the result parameter to the callback function.
{
    "value": "TEXT of whole body (including threads below)",
    "status": "succeeded",
    "asyncContext": "This is passed to the callback"
}

end

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

The end property is a Time 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.

Important: In the Windows client, you can't use this property to update the end of a recurrence.

end: Time;

Method Details

addFileAttachmentAsync(uri, attachmentName, options, callback)

Adds a file to a message or appointment as an attachment.

The addFileAttachmentAsync method uploads the file at the specified URI and attaches it to the item in the compose form.

You can subsequently use the identifier with the removeAttachmentAsync method to remove the attachment in the same session.

Important: In recent builds of Outlook on Windows, a bug was introduced that incorrectly appends an Authorization: Bearer header to this action (whether using this API or the Outlook UI). To work around this issue, you can try using the addFileAttachmentFromBase64 API introduced with requirement set 1.8.

addFileAttachmentAsync(uri: string, attachmentName: string, options: Office.AsyncContextOptions & { isInline: boolean }, callback?: (asyncResult: Office.AsyncResult<string>) => void): void;

Parameters

uri: string

The URI that provides the location of the file to attach to the message or appointment. The maximum length is 2048 characters.

attachmentName: string

The name of the attachment that is shown while the attachment is uploading. The maximum length is 255 characters.

options: Office.AsyncContextOptions & { isInline: boolean }

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. isInline: If true, indicates that the attachment will be shown inline in the message body, and should not be displayed in the attachment list.

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

Optional. When the method completes, the function passed in the callback parameter is called with a single parameter of type Office.AsyncResult. On success, the attachment identifier will be provided in the asyncResult.value property. If uploading the attachment fails, the asyncResult object will contain an Error object that provides a description of the error.

Returns

void

Remarks

Minimum permission level: read/write item

Applicable Outlook mode: Appointment Organizer

Errors:

AttachmentSizeExceeded: The attachment is larger than allowed.
FileTypeNotSupported: The attachment has an extension that is not allowed.
NumberOfAttachmentsExceeded: The message or appointment has too many attachments.

Errors:

NumberOfAttachmentsExceeded: The message or appointment has too many attachments.

close()

Closes the current item that is being composed.

The behavior of the close method depends on the current state of the item being composed. If the item has unsaved changes, the client prompts the user to save, discard, or close the action.

In the Outlook desktop client, the close method has no effect on a reply in the Reading Pane.

close(): void;

Returns

void

Remarks

Minimum permission level: restricted

Applicable Outlook mode: Appointment Organizer

Important: In Outlook on the web, if the item is an appointment and it has previously been saved using saveAsync, the user is prompted to save, discard, or cancel even if no changes have occurred since the item was last saved.

Examples

// Link to full sample: https://raw.githubusercontent.com/OfficeDev/office-js-snippets/prod/samples/outlook/25-item-save-and-close/close.yaml

Office.context.mailbox.item.close();

getSelectedDataAsync(coercionType, options, callback)

Asynchronously returns selected data from the subject or body of a message.

If there is no selection but the cursor is in the body or subject, the method returns an empty string for the selected data. If a field other than the body or subject is selected, the method returns the InvalidSelection error.

To access the selected data from the callback function, call asyncResult.value.data. To access the source property that the selection comes from, call asyncResult.value.sourceProperty, which will be either body or subject.

getSelectedDataAsync(coercionType: Office.CoercionType | string, options: Office.AsyncContextOptions, callback: (asyncResult: Office.AsyncResult<any>) => void): void;

Parameters

coercionType: Office.CoercionType | string

Requests a format for the data. If Text, the method returns the plain text as a string, removing any HTML tags present. If HTML, the method returns the selected text, whether it is plaintext or HTML.

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<any>) => void

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

Returns

void

The selected data as a string with format determined by coercionType.

  } else {
    console.error(asyncResult.error);
  }
});

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

removeAttachmentAsync(attachmentId, options, callback)

Removes an attachment from a message or appointment.

The removeAttachmentAsync method removes the attachment with the specified identifier from the item. As a best practice, you should use the attachment identifier to remove an attachment only if the same mail app has added that attachment in the same session. In Outlook on the web and on mobile devices, 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.

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

Parameters

attachmentId: string

The identifier of the attachment to remove. The maximum string length of the attachmentId is 200 characters in Outlook on the web and on Windows.

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<void>) => void

Optional. When the method completes, the function passed in the callback parameter is called with a single parameter of type Office.AsyncResult. If removing the attachment fails, the asyncResult.error property will contain an error code with the reason for the failure.

Returns

void

Remarks

Minimum permission level: read/write item

Applicable Outlook mode: Appointment Organizer

Errors:

InvalidAttachmentId: The attachment identifier does not exist.

Examples

// The following code removes an attachment with an identifier of '0'.
Office.context.mailbox.item.removeAttachmentAsync(
    '0',
    { asyncContext : null },
    function (asyncResult)
    {
        console.log(asyncResult.status);
    }
);

// Link to full sample: https://raw.githubusercontent.com/OfficeDev/office-js-snippets/prod/samples/outlook/40-attachments/attachments-compose.yaml

Office.context.mailbox.item.removeAttachmentAsync(
    $("#attachmentId").val(),
    { asyncContext : null },
    function(result)
    {
        if (result.status !== Office.AsyncResultStatus.Succeeded) {
            console.error(`${result.error.message}`);
        } else {
            console.log(`Attachment removed successfully.`);
        }
    }
);

removeAttachmentAsync(attachmentId, callback)

Removes an attachment from a message or appointment.

removeAttachmentAsync(attachmentId: string, callback?: (asyncResult: Office.AsyncResult<void>) => void): void;

Parameters

attachmentId: string

The identifier of the attachment to remove. The maximum string length of the attachmentId is 200 characters in Outlook on the web and on Windows.

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

Returns

void

Remarks

Minimum permission level: read/write item

Applicable Outlook mode: Appointment Organizer

Errors:

InvalidAttachmentId: The attachment identifier does not exist.

saveAsync(options, callback)

Asynchronously saves an item.

Since appointments have no draft state, if saveAsync is called on an appointment in compose mode, the item is saved as a normal appointment on the user's calendar. For new appointments that haven't been saved before, no invitation is sent. For existing appointments, an update is sent to added or removed attendees.

saveAsync(options: Office.AsyncContextOptions, callback: (asyncResult: Office.AsyncResult<string>) => void): void;

Parameters

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<string>) => void

When the method completes, the function passed in the callback parameter is called with a single parameter, asyncResult, which is an Office.AsyncResult object. The appointment ID is returned in the asyncResult.value property.

Returns

void

Remarks

Minimum permission level: read/write item

Applicable Outlook mode: Appointment Organizer

Important:

In Outlook on the web or Outlook in online mode, the item is saved to the server. In Outlook in cached mode, the item is saved to the local cache.
When working with HTML-formatted content, it's important to note that the Outlook client may modify the content. This means that subsequent calls to methods like Body.getAsync, Body.setAsync, and even saveAsync may not result in the same content.
If your add-in calls saveAsync on an item in compose mode in order to get an item ID to use with EWS or the REST API, be aware that when Outlook is in cached mode, it may take some time before the item is actually synced to the server. Until the item is synced, using the item ID will return an error.
In Outlook on Mac, only Build 16.35.308 or later supports saving a meeting. Otherwise, the saveAsync method fails when called from a meeting in compose mode. For a workaround, see Cannot save a meeting as a draft in Outlook for Mac by using Office JS API.

Errors:

InvalidAttachmentId: The attachment identifier does not exist.

Examples

// Link to full sample: https://raw.githubusercontent.com/OfficeDev/office-js-snippets/prod/samples/outlook/25-item-save-and-close/save.yaml

Office.context.mailbox.item.saveAsync(function (result) {
  if (result.status === Office.AsyncResultStatus.Succeeded) {
    console.log(`saveAsync succeeded, itemId is ${result.value}`);
  }
  else {
    console.error(`saveAsync failed with message ${result.error.message}`);
  }
});

saveAsync(callback)

Asynchronously saves an item.

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

Parameters

setSelectedDataAsync(data, options, callback)

Asynchronously inserts data into the body or subject of a message.

The setSelectedDataAsync method inserts the specified string at the cursor location in the subject or body of the item, or, if text is selected in the editor, it replaces the selected text. If the cursor is not in the body or subject field, an error is returned. After insertion, the cursor is placed at the end of the inserted content.

setSelectedDataAsync(data: string, options: Office.AsyncContextOptions & CoercionTypeOptions, callback?: (asyncResult: Office.AsyncResult<void>) => void): void;

Parameters

data: string

The data to be inserted. Data is not to exceed 1,000,000 characters. If more than 1,000,000 characters are passed in, an ArgumentOutOfRange exception is thrown.

options: Office.AsyncContextOptions & Office.CoercionTypeOptions

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. coercionType: If text, the current style is applied in Outlook on the web and on Windows. If the field is an HTML editor, only the text data is inserted, even if the data is HTML. If html and the field supports HTML (the subject doesn't), the current style is applied in Outlook on the web and the default style is applied in Outlook on desktop clients. If the field is a text field, an InvalidDataFormat error is returned. If coercionType is not set, the result depends on the field: if the field is HTML then HTML is used; if the field is text, then plain text is used.

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

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

Returns

void

Remarks

Minimum permission level: read/write item
