Did you already see the section in the compatibility guide about Citrix?

Yes.

I just wanted check Enterprise Vault 9  Add- in for Outlook will be compatible to run on  Xenapp on windows 2008/2008R2.

Well the section on Citrix says :

So as long as you stick within those guidelines you should be all set.

Thanks..

When I asked support and they told me windows 2008/2008R2 and the Enterprise Vault 9  Add- in for Outlook is not supported in the compatibility guide. Hence the question.

"*Officially* Windows 2008 is not supported as a client, however this does not mean that EV will *never* work with 2008 acting as a client. It just means that it has not been tested and certified. If customer wants to know if it is *possible*, then get them to create a test environment, but point out that any adverse affects will not be supported by Technical Support should problems arise. "

As I understand the Citrix/XenApp world, when presented out to a client/end-user it's not "really" Windows 2008 R2 tha tthe user sees.  Or is it?  What does the end-user see?  Do you have to publish a desktop OS to the user?  Or just Desktop Apps?

I have checked with Citrix server team here and they have come back with this.

"They would see Windows 2008 r2 whether its a desktop or published app.

 It depends which way we go whether its published app / desktop.

 Again depending on way we go, but if using nfuse then it would be published. "

i've pinged our certification guys, let's see if they know any more.

Certification guys say it is now supported as a client...  Compatibility Guide will be updated on it's next revision.

many thanks
