I've recently set up a new Windows server 2016 RDS enviroment, and I've started some user testing. One user has a problem in Outlook where folders will not update. If a new mail comes in he has to switch to a different folder and then back before it's visible. This is also the case if he deletes, moves, or marks an email. He has to switch to a different folder and back before it's visible.
I've tried setting up a new Outlook profile for him, tried setting up a new Windows user profile (by deleting his user profile disk), and I've tried switching cached exchange on and back off. The problem dissapeared for a day when I started Outlook in safe mode, and then back to normal mode. But now, after logging off and on to the terminal server, the problem is back.
I have another test user in the same enviroment, and she is not experiencing any problems. Both users have used Outlook 2013 on Windows 2008R2 for a long time, with the same Exchange accounts, without ever facing this problem.
Any tips for me?
