Microsoft 365 web Add-in (API) development status

Copper Contributor

Hello all,


I just ping you to inquire about the current status of Web Add-in Development for Microsoft 365 ( Looking at the current in work items and the completed items, there doesn't seem to be progress at all right now. The completed items are often just marked as that because feedback portals moved, or the idea won't happen. So not a single really fixed thing in over a year now, I guess.


So with all of this, is Add-in API development just stalled? I don't really get it. You have tons of useful requests that would really greatly improve the usability of the platform and could result in Add-ins adding value to it.


Should I just use the old, non web based Add-in API instead? This is pretty frustrating.


I hope to get a response on this. Possibly, you can also forward me to another person, who might be more suited to answer my questions and take my feedback on this.


Apparently, there is more activity on the GitHub issue tracker, BTW:
