Description

There's an issue accessing Office 365 through Squid depending on the users location.

This is due to the way Microsoft load balance Office 365 (And deny access to certain IP's from different locations).

The default Squid value for "forward_max_tries" is 10 - This should be set to 25 in order to allow Office 365 to work with a NethServer proxy worldwide.

Adding the following line to /etc/squid/squid.conf fixes the TCP_MISS/503 for the caching as well as enables Office 365 to be accessed through it:
forward_max_tries 25
