Outlook 2016 and Office 365 issues

[mdrabble]

Just recently a number of users have said they are experiencing issues where outlook start running painfully slow and outlook reports connection issues with Office 365.

 

I'm wondering if it could be an update causing this but before I start removing updates, has anyone else seen or suffered issues like this?

 

Cheers

Yeah we did, a lot of it was solved by adding all of the relevant MS sites to HTTPS inspection exception lists in our firewall/filtering, although every now and then they do have rather a fart which I'm sure is down to Outlook more than anything else. My outlook 2016 is certainly a PITA, often it'll just hang there not responding then come to life later, to the point where I resort to using OWA.

We are having the same problems with 2016/O365 - Do you happen to have the list of the MS sites that i would need to add to the exception lists?

 

Thanks.
