Office 365 - Sophos UTM SSL Inspection

[colly72]

Hi all,

 

I'm setting up a trial of Office 365 and I've successfully set up authentication using AD Azure Connect. Everything works fine and I can log in to Office 365 using my school AD account, except when SSL decryption is turned on on our Sophos UTM. Usually, I'd create an exception to get round any SSL scanning issues but I've tried this with some urls I've found from googling the web but I still can't login to Office 365 unless SSL scanning is turned off. I can't even seen any blocked URLs in our web filtering log to indicate what might be the issue.

 

Does anyone have any experience on getting this working?

 

Thanks in advance.

I think I've fixed it. I needed two extra Urls in the exception list:

 

^https?://([A-Za-z0-9.-]*\.)?msappproxy\.net/

^https?://([A-Za-z0-9.-]*\.)?servicebus\.windows\.net/

 

This seems to have done the trick.
