FortiClient Web-Filter blocks from MSTeams (Access via IP?)

Hello everyone,

I did enable web filter on our FortiClients when outside company LAN.

 

Some users notified me that they get a lot of pop up notifications from FortiClient:

 

It seems like FortiClient does block some IPs that belong to Microsoft teams (according to ioc.fortiguard.com).

 

These IPs get blocked over several clients.

Any ideas how to fix this? As far as I know normally there is the URL shown in these logs, seems like Microsoft Teams accesses to IP directly without DNS?

Hi,
check this link --> https://learn.microsoft.com/en-us/microsoft-365/enterprise/urls-and-ip-address-ranges?view=o365-worldwide 

Microsoft use domain and ip for there communications. 

add the blocked IP address to allowed web category and check if the issue is fixed.
