Hi,
We have M365 Business Premium and I currently run SOPHOS Endpoint Adv + Intercept X for local scanning & Proofpoint as our email smart host (AV/Spam/etc).
Regarding Proofpoint and M365 Defender, are there any steps to be aware of, prior to upgrading? We have custom inbound/outbound mail connectors for Proofpoint and also one for Exclaimer (email signature manager).
I've read articles about being aware if you use a smart host, but nothing concrete on specific settings to disable/tweak to ensure defender doesn't impact email delivery.
Thanks for any advice offered.
Darren.
