Global protect and Outlook 2016

Recently we observed an issue for users on GP and using outlook.

When the GP is etablished and if the user launches Outlook in less than 1 min the outlook throws the error

"we are unable to connect right now. please check your network and try again later"

The same user once connected to GP and tried to launch post 1 min the outlook works fine

I am unable to link to GP or generic Outlook behaviour, any pointed from the community is highly appreciated.

I am having the same issue- it is random- Users are able to connect to GP and access everything except Outlook and Skype for business. No resolution yet as to what the issue is.

Did you see the Post in this thread earlier from Rajjair?  This was the fix for me, I needed pre-logon policies allowing access to   Looking at my rule I've also added, can't remember if that also related to this issue.


I'll repost the text below since it also explains the issue well, credit to Rajjair.



had the similar issue and was able to to trace it down NCSI causing the problem, the probe HTTP was failing for me. You can check windows event logs to see if you are facing the same issue - Microsoft-Windows-NCSI/Operational


This is logged in the event it was failing:

Capability change on {57a83755-d89b-4a01-a72d-d4786875d856} (0x6008009000000 Family: V4 Capability: None ChangeReason: ActiveHttpProbeFailedButDnsSucceeded)


I need to allow "" this site access in pre-logon policy.
