Outlook 2016 unable to open while on GlobalProtect

Anyone else experiencing issues with Outlook 2016 being unable to open while on GlobalProtect?  We have sporadic windows 10 pc's with this problem and all windows 7 pc's have this issue.  When we disable GlobalProtect and start Pulse Secure (our legacy VPN agent), Outlook opens right up and connects.  We have a ticket open, but I'm guessing TAC is slammed right now.

Hello,

Are you using split tunnel VPN or full tunnel? What do the traffic logs say with regards to the traffic, allow/deny? My guess is that it might be denied?

 

Regards,

We're currently running split-tunnel, but the split tunnel is only to exclude a few domains not related to O365.  I'm not finding ANY denied logs.  We even added FULL internet access based on any, any, any with no IPS, URL, etc.  Still failed.

 Is there any finding as to the issue?  We have the same problem with some clients whereby you need to disable global protect and start outlook first.  Thanks
