We are currently using an in house Exchange 2007 and Message labs for inbound and outbound mail.
We are moving over to Office 365.
If I set up all the MX records as per Office 365 wizardry, I assume this will completely bypass Message Labs.
Do we need to keep Message Labs now or will Office 365 do a similar job with catching spam etc.
If we do want to keep message labs which DNS records do I have to set up, and which bits do I key into Message Labs Inbound and outbound set up. It would be nice to keep it for a while just in case we have to switch back,
