All mailboxes are associated with my account?

We just set up an Exchange 2010 server to replace our old Exchange 2003 server. I migrated all of the user mailboxes over to the new server.

Here is the problem. Every mailbox on the entire exchange system is associated with my account. (see Screenshot-allmailboxes). When I open Outlook it shows everyone's mailbox on the left side. In a minute or two it freezes up and tells me that my system is out of memory.

When I right click on one of them and choose to close that mailbox is tells me that can't remove it because it is associated with my account. (see screenshot-cantRemoveFolders).

I follow the directions and go to File > info > Account settings and the only email account I see in there is my own so I can't remove the others.

How do I disassociate these with my account? I'm assuming that there is some setting in exchange that will fix this. Please help!

That is because you have Full Access rights to all mailboxes. This is automatic.

You need to remove full access and Send on behalf of, then they should go away.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

I'm wondering what tools were used to migrate.  I would think that it would be best and fastest to delete all the mailboxes on the 2010 side and just start over, making sure that the mailboxes still exist on the 2003 server before deleting on the 2010 side..

Did you use the "Move Mailbox" feature from Exchange 2010 console/EMS?

No, I never could get the move mailbox feature to work properly. I ended up using outlook to connect to each mailbox on the old server and export to a PST. I then created a new mailbox on the new server and used outlook to import the PST file. This is why I granted myself access to their mailboxes.

I guess all I need to remove myself from the manage full access. I'll try that now

That explains why you have full access to all mailboxes...
