I have the issue where outlook 2016 will not work with my vpn turned on. If I turn off the vpn, outlook 2016 works fine. With the VPN turned ON then Outlook 2016 will open up OK BUT it will NOT download/ update emails. Error message states "We are unable to connect right now. Please check your network and try again later"
In the notification area along the bottom of the Outlook 2016 page it says "This folder has not been updated". Also says "Disconnected" which then changes to "Trying to Connect".
Also get the same issue with One Note, it does open but says "One note needs a password to sync this this notebook."
All ok with NO VPN
