Protect network traffic blocks EWS service URL from within a program

Hello, we have a problem with the feature “Protect network traffic”.

We are using a terminal server, on which employees work with a program that uses EWS to send mails.

We now have the problem that Sophos blocks the automatic login process via the Service URL

We have already tried setting process exceptions for the program, web exceptions for the Microsoft office addresses and IPS exceptions for the Microsoft IPs.

Its also strange that sometimes a connection comes through. If you spam the login process you will sometimes get connected, but only rarely.


I would be thankful for any tips that you have for that problem, and I am sorry if my English is a bit rusty.
