Issue:
I have user whose Outlook 2016 does not update new mails. mails are received only after restarting outlook.
What I have tried:
- Recreating profile.
- Opening outlook in safemode
- Manual send/receive
- Reset navpane
- Turned off addin like vba, symantec, outlook social connect.
- Work offline if off.
Wifi speed is good 5 GHZ. Clients connects from a VPN. Download speed 20 MBps. i'm now out of ideas. OWA receives mail properly.
