Since getting no response to this, I shelved the problem for a while. Happily though, I worked out the solution while fixing an IE link issue I was having in Outlook 2010 on a Citrix Xenapp farm.   Outlook 2010 does not use the HKCR\http protocol type listed in the vWorkspace admin guide for opening its links, despite the fact that all the other Office applications do. To get Outlook to redirect links you have to change this:  HKEY_CLASSES_ROOT\htmlfile\shell\opennew\command Default REG_SZ = "C:\Program Files (x86)\Quest Software\vWorkspace\IE Redirection\iexplore.exe" %1
I have an RDSH server with the following configuration: Windows Server 2008 R2 Service Pack 1 build 6.1.7601 vWorkspace 8.0.0.1167 RDSH & Connection Broker roles Microsoft Office 2010 version 14.0.6129.5000 32 bit Internet Explorer 10.0.9200.16635  I am trying to implement IE redirection of URLs from the server to the client. I have configured the following registry value as per the admin guide: HKCR\http\shell\open\command Default REG_SZ "C:\Program Files (x86)\Quest Software\vWorkspace\IE Redirection\iexplore.exe" %1  If I look in Control Panel\All Control Panel Items\Default Programs\Set Default Programs\Set Program Associations, the current default for HTTP is shown as Quest vWorkspace Internet Explorer.  If I open links in Word, Excel or wordpad the URLs are redirected to the local IE as expected. However, links opened from Outlook always open in Internet Explorer in the RDSH session.  Is there anything else I need to set to get links to redirect in Outlook?  Any help appreciated.  Scott.
