Hey folks! I have a XG firewall on 18.5.2. For the last year or so, we have been having trouble with random users being prompted to put their Outlook password in for the desktop app. I have been chalking it up to Microsoft being eh. But this week it has gotten really bad. To the point where I have many users that can't use the Outlook desktop app at all.
In researching that issue today, I found that firewalls can be a cause for this issue with Outlook. Apparently Outlook does this when it has a spotty internet connection. So, I started looking through the XG Firewall logs. I found that there are a very large amount of items that say "Invalid Traffic" and "Could not associate packet to any connection." Every single instance of this happening has a destination IP going to Microsoft. Call me crazy, but I don't think that is a coincidence.
I have tried creating a firewall rule to allow all traffic going to the IP range, and it has made no difference. Does anyone have an idea as to why the XG is terminating connections with Microsoft's servers at an alarming rate? It's essentially breaking the most important part of our internet. Surely I am not the only person this has happened to. I have found a couple threads with similar issues brought up, but there is never a resolution that applies (that I have been able to find).
