将Outlook加载项部署到Citrix XenApp安装

Question

I created an Outlook addin. It does nothing special, just adds a menu with one menu item. I followed the installer creation tutorial from http://blogs.msdn.com/b/mcsuksoldev/archive/2010/10/01/building-and-deploying-an-outlook-2010-add-in-part-2-of-2.aspx .

It installs and works properly on a normal windows desktop installation, but I cant figure out how to do it in a Citrix XenApp environment. I can install it using the installer in the same profile where the Outlook is installed successfully. But when Outlook is run, it is in the "Inactive Application Addins" section when I view it from the Trust Center menu, and it wont activate properly. If I open the Manage COM Addins menu, it displays "Load at Startup" as my addin's Load Behavior. If I try to activate it manually from this menu, nothing happens, and if I open it again, Load Behavior will change to "Not Loaded. The Managed Add-in Loader failed to initialize."

Anyone encountered this or something similar before? Thanks in advance.

If it's installing but inactive then it's probably throwing an exception upon startup.

I'd wrap all of your startup code (ThisAddIn_Startup function inside your ThisAddIn.cs) inside a try {} catch {} and log all errors out to disk so you can see why outlook is disabling your addin.

Have you tried setting the VSTO_SUPPRESSDISPLAYALERTS environment variable to see if you can get outlook to give you more info?

(BTW I have found outlook VSTO's to be flaky. Sometimes they just refuse to install and work.)
