CAS Array & Outlook

Hi,

Wonder if this is possible.

I have 4 Databases in Exchange 2010 and 2 of them were created before the CAS Array was setup.

Now I am not sure which Outlook Profiles were setup pointing to the CAS server rather than the CAS Array.

Is this a command that can give me this info ? My Outlook clients use Outlook Anywhere and none of them are part of the domain that my Exchange is a member of.  

This command would be helpful because it would determine which users I need to visit to recreate their Outlook profile.

Thanks
