Support » Plugin: Postman SMTP Mailer/Email Log » No longer able to send via

  • Hi all,

    The problem is most likely with Microsoft, but I figured I try my luck here anyway.

    2 sites have been successfully sending emails via, port 587, until about 2 days ago. Now all emails fail with

    5.3.4 554 5.2.0 STOREDRV.Submission.Exception:SendAsDeniedException.MapiExceptionSendAsDenied; Failed to process message due to a permanent exception with message Cannot submit message. 16.55847:69000000, 17.43559:0000000060010000000000000100000000000000, 20.521

    Has anyone else come across this issue as well?
