Hi All,
we use a Windows Server 2016 RDS Deployment with three virtual Machines: the first VM is the classic Terminalserver Desktop where all users connect to from their client PCs, the two others are RDS Hosts with some RemoteApps, like Outlook 2016.
Sometimes this happens:
1. a User connects to the terminalserver by RDP ( not using RD Gateway, Native Port 3389 )
1. the User starts Outlook as Remoteapp on the Terminalserver ( RDP Icon on the Desktop, Connecting by RD Gateway )
2. the User clicks on "New Mail", a window opens, he writes the content and sends it, the windows closes, everything is fine ;-)
3. the User clicks on "New Mail" ( or wants to forward an existing mail ), a windows opens - this window shows the content of the previous e-mail (from 2.) - it is not possible to hit or edit the elements in the windows, it's just graphic ...
This behaviour is confusing the users.
Workaround: resizing the windows solves the problem, after this the user use the window, can edit ...
It seems that the graphical content is cached somewhere, so we disabled "bitmap caching" in the rdp Settings on the Client PC and in the rdp Settings for Outlook on the Terminalserver - nothing changed.
Sometimes the behavior occurs after writing 10 to 15 E-Mail, sometimes after every E-Mail. There is no regularity. The Load on the VMs isn't high, enough RAM.
Do you have any ideas ?
Best Regards,
Karsten
