Hi, I am trying to script a way to export Shared mailboxes settings from the current user to a text file, as a reference of what they had and what could possibly be required to set them up (manually) if requested in the future.

Under Exchange 2007 & 2010 you can use powershell to document what they could have access to, but I have been unable to figure out what the Client has setup within thier Outlook client.

The 30,000 users to do, 500 as a test run.

Summary - How can I script an export list of a users current Shared mailboxes they have steup within thier Outlook client?

You can't easily get this from outlook - its stored in the registry. AFAIK, its not stored anywhere server side, so you'd need to read the registry.

its under HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\[profile-name] somewhere... probably as a binary value.
