Issue: Unauthorized to post message in Teams channel

Dear colleague-builders,


I have several flows that were functioning until today and integrated Outlook, Sharepoint and Teams. Today, however, I experienced issues with all of them related to the posting of messages on Teams. It keeps on saying that I'm unauthorised to post messages on a specific channel and therefore the flow stops working. 


I changed my Office 365 password today and so, I'm suspicious that it has to do with this. While I have checked all of my rights (which grant me the full ability to post messages on the specific Teams channel), have checked all the connections in Power automate for the specific flows and in general, did reset them and signed in again on Teams, the issue keeps on coming back. It seems to work for 1 or 2 runs, but after that the problem returns.


Could you help me out?

I've had this exact issue today. After changing my organisational account password, any Teams actions involving posting to a channel (either as flow bot or user) have ceased working. How do we escalate this?
