Hello Christine,
Good day! Thank you for posting in Microsoft Community.
I have gone through your concern, I have also consulted your thread with my members, and we have checked few things, but currently there are not any particular feature options available to sync this part of the workflow.
We do understand your concern about this feature that how it helps you to improve your efficiency in such daily busy work schedule but as it is related with "Remove Flag from Email When Marked as Resolved in Teams" product design, so it is suggested to submit your valuable feedback directly to Microsoft product development team by either go to Help from your dedicated App > submit Feedback or by posting on Ideas · Community (microsoft.com) . This is required because as we are from community team, we can only assist you to troubleshoot the query/share work around (if we have for any by design query) and providing you required information for feature’s availability status.
This community team and Microsoft product development team are separate. So for feature’s suggestion or by design query, user need to submit feedback from their side to Microsoft product team. Once user send feedback via above mentioned way, it’s sent to Microsoft directly and it's routed to the relevant product teams who can review it.
To check more details about how to submit feedback, kindly refer this article Learn about how to provide feedback to Microsoft - Microsoft 365 admin | Microsoft Learn
Thank you for your kind understanding. Your patience and cooperation are much appreciated.
Sincerely,
Nafis Iqbal Shuvo | Community Moderator
