We have on-prem Excange Server 2019, and recently we are not able to send an email with attachments.
The error we receive is:
"EasSendFailedPermanentException: An EAS Send command failed: The EAS command failed with Status MailSubmissionFailed, Code ='120' and HttpStatus OK. --> The EAS command failed with Status MailSubmissionFailed, Code ='120' and HttpStatus OK.
Failure code: 4650"
Please advise.
