Server 2008 R2 SP1, with Remote Desktop Services.

Office 2013.

[Edit: Most] Microsoft updates installed.

Publish Outlook as a RemoteApp, and run it from a Windows 8 client, then open an email. What happens is this:

Outlook graphical glitch

  • The email opens and renders briefly, but the Outlook inbox becomes partly-visible through the email.
  • Most of the email is invisible, as if it was in the background, except the border remains visible like an embossed imprint.
  • The partly-invisible email is actually in the foreground, the visible Outlook main window is in the background.

Moving things around, clicking on them, causing a refresh, fixes the display. Sometimes waiting does. It happens pretty much every email, but not exactly every one.

Disabling hardware acceleration in the Outlook options doesn't make a difference, nor does disabling add-ins, nor does changing the LoadBehaviour in the add-in registry entries.

Using a full remote desktop session, Outlook works fine.

It happens on multiple Windows 8 clients, too. Not sure about Win 7.

Any ideas, please?

[Edit: Disabling themes, menu animations, bitmap cache persistance, font smoothing, etc. in the RDP connection - all make no difference].

[Edit: Also tried: - Disabling desktop composition, and menu/window animations on the server - Running Outlook in 'safe' mode (with Outlook.exe /safe) - Changing Outlook theme - Connecting to my PC using RDP, then opening the remote app, to try and get around it being my video drivers. - The latest round of Windows/Office updates on the servers. - Removing/recreating my RDS User Profile.

All no change.

Tried on 3x Windows 8 PCs, all exhibit this behavior. Tried on 3x Win 7 PCs, only one does this, the other two appear OK.


  • Do all of the Win8 clients have the same graphics card / driver set? If so, it might be worth testing a differing one. I strongly suspect this to be the client's problem. – the-wabbit Aug 22 '13 at 15:57
  • Nope, I have Radeon 4000/5000 series, the other main one has an ATI FireGL, and I've just watched it happen on a Windows 8 / nVidia client and a Win 7 nVidia client. – TessellatingHeckler Aug 22 '13 at 16:16
  • Added updates in an edit. – TessellatingHeckler Aug 23 '13 at 21:02
  • There is a hotfix for a problem which sound remotely related. Check out support.microsoft.com/kb/981156/en-us and see if it helps matters. – the-wabbit Aug 23 '13 at 21:37

A post in the Microsoft Partner Support Forum did yield these two possible approaches:

  1. enable RDP 8.0 via the update 2592687
  2. install the hotfix from KB2786923

but none seemed to ultimately fix the specific issue, yet they might be worth trying.

  • This is probably more of a comment than an answer. – Drew Khoury Sep 2 '13 at 10:22
  • I can't see your post, as I have no login that works. Did you get any answers that helped? – TessellatingHeckler Oct 2 '13 at 19:27
  • @TessellatingHeckler check out the post's update – the-wabbit Nov 19 '13 at 19:46
