Migrate to M365 Defender with smart host
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.
- hi Darren,
I wouldn't be worried about the Proofpoint if you're making any changes on mail flow.
if you're moving out of SOPHOS Endpoint Adv deploying M365 Defender just stick with MSFT recommendations https://learn.microsoft.com/en-us/microsoft-365/security/defender-endpoint/migration-guides?view=o365-worldwide and https://learn.microsoft.com/en-us/microsoft-365/security/defender-endpoint/switch-to-mde-overview?view=o365-worldwide ,
