Best practices for implementing access to Office 365?

L3 Networker

Does PAN offer any formal guidance for implementing access to Office 365, specifically for Outlook access to Exchange Online?

We have, via trial-and-error, enabled this access using the newly-minted AppID for Office 365, but are seeing occasional Outlook session disconnects.

Microsoft is, predictably, telling us that none of their other customers see this problem, and are vaguely suggesting it's our firewall.

Does Palo Alto Networks have any recommendations on how to best enable Exchange Online? Anyone have any positive experiences to share? (I can also share some of our pains in reverse-engineering the O365 service, if there is interest...)



Some good info here.  We are getting ready to configure some security policies and I was hoping to see how others were handling it.   

One of my thoughts was / is ....

Well we are getting ready to implement Panorama, so I was thinking that we could setup a global rule that is application based and then a local rule that is URL based, then monitor traffic and see which way is the most effective.
