Outlook has been randomly crashing for some of our users after we applied our monthly Microsoft patches with RTFHTML.DLL and ACTIVEDS.DLL error messages below when they are performing standard tasks such as viewing emails or trying to print.
To fix the issue, we added the following registry keys to our XenDesktop Windows 7 and Windows 2008R2 Images.
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\CtxHook
Vaule Name: ExcludedImageNames
Value Type: REG_SZ
Value Data: Outlook.exe
HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\CtxHook
Vaule Name: ExcludedImageNames
Value Type: REG_SZ
