Office client application and platform availability for Office Add-ins

Note

The initial Office 2016 release installed via MSI only contains the ExcelApi 1.1, WordApi 1.1, and Common API requirement sets. For more information about the update history of the various Office versions, check out the See also section. Office Add-ins may not be supported on all services that are members of the Office Cloud Storage Partner Program, which enables integrating Office on the web to work with Office documents as part of their service offering. For more information, please contact the member service.

Note

¹ Add-ins don't work in modern Outlook on the web on iPhone and Android smartphones. For information about supported devices, see Requirements for running Office Add-ins.

² Add-ins aren't supported in Outlook on Android, on iOS, and modern mobile web with on-premises Exchange accounts. Certain iOS devices still support add-ins when using on-premises Exchange accounts with classic Outlook on the web. For information about supported devices, see Requirements for running Office Add-ins.

³ To require the Identity API set 1.3 in your Outlook add-in code, check if it's supported by calling isSetSupported('IdentityAPI', '1.3'). Declaring it in the Outlook add-in's manifest isn't supported. You can also determine if the API is supported by checking that it's not undefined. For further details, see Using APIs from later requirement sets.

⁴ Added with post-release updates.

⁵ Support for the new Mac UI is available from Outlook Version 16.38.506. For more information, see the Add-in support in Outlook on new Mac UI section.

⁶ Although classic Outlook on Mac doesn't support Mailbox requirement set 1.9, it does support the DialogApi 1.2 requirement set. For information on the minimum supported version and build, see Dialog API requirement sets.

⁷ Although Outlook on Android and on iOS support up to requirement set 1.5, your mobile add-in can now implement some APIs from later requirement sets, such as APIs related to event-based activation. For more information on which APIs are supported in Outlook mobile, see Outlook JavaScript APIs supported in Outlook on mobile devices.
