We’re having issues sending user management invite emails via Exchange Online SMTP. The following error is output:
ResponseError: There is a problem with your SMTP setup! 140372212864960:error:1408F10B:SSL routines:ssl3_get_record:wrong version number:…/deps/openssl/openssl/ssl/record/ssl3_record.c:332
Apparently STARTTLS is only supported by Exchange Online, might that be the cause?
Any feedback is appreciated, thanks!
