Sophos Email customers using IP-based mailflow rule connectors must migrate to certificate-based configuration by March 31st. To see if you're affected Click Here.

Duplicate emails in O365 (or M365) message trace reports.

Sorry in advance if this has already been asked/answered before.....

Current Sophos configuration:  we are using Sophos email flow rules for inbound and outbound email.  We are NOT relaying email through Sophos email server.

Everything is working as it should but when pulling message trace logs for users, I have noticed every email is duplicated in the message trace log.  Does not matter if the email is inbound or outbound.  Message trace logs only started doing this since only since we started using Sophos email protection.

Why would this be happening and is there any way to correct this?

Any help greatly appreciated.
