If I publish an update to an existing Office add-in in AppSource, is that update pushed out to users automatically?
How do I make sure that users receive updates?
If you wish to update an Office add-in currently published on AppSource, you will need to resubmit the add-in to validation. Once the add-in has been reviewed by the validation team, assuming no issues are found, it will be approved and the add-in update will be automatically rolled out to existing users who acquired the add-in via AppSource.
