No longer able to send via outlook.com
-
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 smtp-mail.outlook.com, 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?
