I'm attempting to clean up my AD and Exchange mailboxes ( for a migration to 365) but I've run into a snag. It turns out that I have a number of departments that are using shared calendars that were created and shared by former employees.
Environment: Server 2008R2, Exchange 2007, Outlook 2010.
Most of these calendars were not created as rooms, or in a public storage container like 2000 used to use. They are all end user created, shared and stored.
The problem is I can't delete a lot of these inactive user accounts because of these shared calendars. I want/need to find ALL of them (meaning any user account with a shared calendar), export them and move them to a room so I don't have to worry about personnel changes anymore.
Is there a way to find all of these shared resources (calendars) in PowerShell?? I can't really ask my end users. Many of them still think "deleted items" is a storage compartment.
