Hello. We've recently switched to Office 365. We have a group of users we would like to restrict Internet access to only Office 365 services. Does anyone have any experience they can share with doing this?

Hi,

In FortiOS 5.6 and higher, you are able to create rules with Internet Service Database. I'm using the following entries:

- Microsoft-Office365

- Microsoft-Outlook

You permit this rule just above your restricted rule. These entries are updated by Fortiguard frequently!

Thank you. I've done that. Outlook can connect and send/receive. However, I've noticed that it takes up to 2 minutes for Outlook to launch. When the workstation has full Internet access, Outlook loads immediately. Not sure what's hanging it up with the suggested configuration.

Hi,

It looks like a DNS or Azure AD issue. There is requests blocked at that time. Packet sniffer can help to find with IP are needed on wich protocol.
