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.'
