I made my first Outlook web add-in and I was wondering how I could place the button right here automatically without going into the OWA settings by hand. Is there a way a place it here via the manifest? I tried looking up online the manifest syntax but I could not find how to do it on the official DOCS.
This is out of scope for a developer. But users can install the add-in and the add-in can be pinned to the email items for easy access.
