Application Control Blocking Microsoft.Outlook.Office.365

[fscheun]

Hi All

We're encountering an issue whereby access to O365 is not permitted. This applies to web access and Outlook clients connecting to o365. Upon investigation I noticed application Microsoft.Outlook.Office.365 is being blocked on our application control profiles on all my firewalls. Adding an override to the Application Control Sensor resolves the problem. Does anyone know if anything changed on this Mircrosoft Application Signature, or perhaps if the risk level classisfication on FortiGuard?

Would appreciate any insights.

Regards,

Francois
