MySergius Do you still have the same problem? And if so do you have the same problem when you send to different channels? My guess is that there were some temporary problem in the mail relay handling emails to Teams channels.

    HelloMySergius 

    is your problem resolved? and how ?

    I have the same error message when I redirect an external mail to a Teams channel (via the automatic exchange mail redirect)

    Remote Server returned '554 5.4.182 Problem occurred during the delivery. Exception Message:The remote server returned an error: (400) Bad Request.'
