Hello Everyone,
So it seems we are facing a new issue. Up to now we haven't experienced any issues with the Password of the day function for Sophos. Currently, we have an SG105 in place at a client. I noticed after awhile that no emails were getting sent. Since then I realized that it, the firewall, will send to any emails such as self-hosted, etc. However, it will not send an email to any Office 365 accounts?!
So far we have messed with whitelisting, spam filter, rules, and looked through other settings in Office. We contacted a Sophos rep who didn't seem to know what to exactly do. The most information I could find was when I performed a message trace and received the following
"Office 365 received the message that you specified, but couldn't deliver it to the recipient (****.com) due to the following error:
Error: 550 4.3.2 QUEUE.TransportAgent; message deleted by transport agent
A non-delivery report (NDR) message was sent to *sender*. The NDR might provide more details about why the email message wasn't delivered and how to fix the issue."
I really hope someone can help with this. It would be great to figure this out so we can document it for the future!!
Thanks,
Mike
