WebApplicationInfo element

Supports single sign-on (SSO) in Office Add-ins. This element contains information for the add-in as both:

• An OAuth 2.0 resource to which the Office client application might need permissions.
• An OAuth 2.0 client that might need permissions to Microsoft Graph.

Add-in type: Task pane, Mail, Content

Valid only in these VersionOverrides schemas:

• Task pane 1.0
• Content 1.0
• Mail 1.0
• Mail 1.1

For more information, see Version overrides in the add-in only manifest.

Associated with these requirement sets:

• IdentityAPI 1.3

Note

The single sign-on API is currently supported for Word, Excel, Outlook, and PowerPoint. For more information about where the single sign-on API is currently supported, see IdentityAPI requirement sets. If you're working with an Outlook add-in, be sure to enable Modern Authentication for the Microsoft 365 tenancy. To learn how to do this, see Enable or disable modern authentication for Outlook in Exchange Online.
