 # Office Add-ins manifest
 
 Every Office add-in has a manifest. There are two types of manifests:
 
-- **Add-in only manifest**: This is the only type of manifest that's currently supported for non-Outlook add-ins. Its format is XML. This type of manifest can't be used for an app that combines an add-in with some other kind of extension of the Microsoft 365 platform.
-- **Unified manifest for Microsoft 365**: This is an expanded version of the JSON-formatted manifest that has been used for years as the manifest for Teams Apps. Add-ins that use this manifest can be combined with other kinds of extensions of the Microsoft 365 platform in a single app that's installable as a unit.
+- **Add-in only manifest**: This type of manifest can be used for production add-ins in Excel, OneNote, Outlook, PowerPoint, Project, and Word. It can't be used for an app that combines an add-in with some other kind of extension of the Microsoft 365 platform. Its format is XML.
+- **Unified manifest for Microsoft 365**: This is an expanded version of the JSON-formatted manifest that has been used for years as the manifest for Teams Apps. Add-ins that use this manifest can be combined with other kinds of extensions of the Microsoft 365 platform in a single app that's installable as a unit. You can use this type of manifest for production Outlook add-ins. It's available for preview in Excel, PowerPoint, and Word add-ins.
