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 property returns the Exchange Web Services (EWS) ID of the parent (series) item that this item belongs to. However, in Outlook on Android and on iOS, 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 isn't 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 don't have parent items such as single appointments, series items, or meeting requests and returns undefined for any other items that aren't meeting requests.

Minimum permission level: read/write item

Applicable Outlook mode: Appointment Organizer

Important:

• This method isn't supported in Outlook on iOS or Android. For more information on supported APIs in Outlook mobile, see Outlook JavaScript APIs supported in Outlook on mobile devices.

• In recent builds of classic 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, use the addFileAttachmentFromBase64 API introduced with requirement set 1.8.

• The URI of the file to be attached must support caching in production. The server hosting the image shouldn't return a Cache-Control header that specifies no-cache, no-store, or similar options in the HTTP response. However, when you're developing the add-in and making changes to files, caching can prevent you from seeing your changes. We recommend using Cache-Control headers during development.

• You can use the same URI with the removeAttachmentAsync method to remove the attachment in the same session.

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.

Examples

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

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

The addFileAttachmentFromBase64Async method uploads the file from the Base64 encoding and attaches it to the item in the compose form. This method returns the attachment identifier in the asyncResult.value object.

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

Note: If you're using a data URL API (e.g., readAsDataURL), you need to strip out the data URL prefix then send the rest of the string to this API. For example, if the full string is represented by data:image/svg+xml;base64,<rest of Base64 string>, remove data:image/svg+xml;base64,.

Adds an Exchange item, such as a message, as an attachment to the message or appointment.

The addItemAttachmentAsync method attaches the item with the specified Exchange identifier to the item in the compose form. If you specify a callback function, the method is called with one parameter, asyncResult, which contains either the attachment identifier or a code that indicates any error that occurred while attaching the item. You can use the options parameter to pass state information to the callback function, if needed.

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

If your Office Add-in is running in Outlook on the web and new Outlook on Windows, the addItemAttachmentAsync method can attach items to items other than the item that you're editing. However, this isn't supported and isn't recommended.

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 Outlook on Windows (classic) and on Mac, the close method has no effect on a reply in the Reading Pane.

Parameters

Returns

Remarks

[ API set: Mailbox 1.8 ]

Minimum permission level: read item

Applicable Outlook mode: Appointment Organizer

Important:

• 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.

• If your add-in calls getItemIdAsync (for example, 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 synced to the server. Until the item is synced, the item ID isn't recognized and using it returns an error.

Errors:

• ItemNotSaved: The ID can't be retrieved until the item is saved.

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

Returns

Remarks

[ API set: Mailbox 1.1 ]

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, 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.

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

Parameters

Returns

Remarks

[ API set: Mailbox 1.1 ]

Minimum permission level: read/write item

Applicable Outlook mode: Appointment Organizer

Important*: The removeAttachmentAsync method doesn't remove inline attachments from a mail item. To remove an inline attachment, first get the item's body, then remove any references of the attachment from its contents. Use the Office.Body APIs to get and set the body of an item.

Errors:

• InvalidAttachmentId: The attachment identifier does not exist.

Examples

// 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")

    console.log("Event handler removed successfully.");
});

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

Returns

Remarks

[ API set: Mailbox 1.3 ]

Minimum permission level: read/write item

Applicable Outlook mode: Appointment Organizer

Important:

• In Outlook on the web, new Outlook on Windows, or classic Outlook on Windows in online mode (non-cached 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.

• The identifier returned is the same as the Exchange Web Services (EWS) item identifier. 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.

• If your add-in calls saveAsync 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 Version 16.35 (20030802) and 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.
