When will the ability to access hidden O365 Outlook mail folders move from the Graph Beta to Production?

Question

We have a number of customers that would like us to be able to collect emails contained in hidden Outlook mail folders. I know this is supported in Beta, but we can't use Beta for production use. Is there a mechanism for escalating deployment of Beta functionality to production?

Answer 1

ok @Greg Evans the capability to access Hidden Mail Folders via Graph was moved to GA/Production in Build-21 (last week). Here's the public documentation for it.

Answer 2

As far as I know, this will not be possible as the Engineering team usually has their own priorities. One way that you can communicate is to find and upvote or create the feature request for it on Microsoft 365 Developer Platform
