I just started using power automate, so the "mail" flow is not available. I'm using the office 365 outlook connection. I picked "send email from shared mailbox" and I chose a MS Teams group that I am part of.
it fails with the error Group Shard is used in non-Groups URI. clientRequestId: *** serviceRequestId: ****
(there are numbers for the client and service requestID I just didn't know if they were part of the error code or a guid for my MS teams)
if there is another way to have it send as a generic email address other than using a shared mailbox, that would work also.
