Removing managed mailboxes from an Outlook profile

Following a server migration, an administrator had user's mailboxes showing up in his profile. This was the result of giving himself Full Access permission to the mailboxes during the migration.

When a user has Full Access permission to another user's mailbox, Outlook 2007 and above automatically opens the mailbox in the profile. (The mailboxes were not listed as secondary mailboxes in Account Settings.)

The administrator removed Full Access permission for the mailboxes but this didn't remove the accounts from his profile.

Following an Exchange server upgrade, I have several users mailboxes in my profile. I cannot close the mailboxes. The accounts are not listed as additional mailboxes in my profile. I removed Full Access permissions. Any idea of how to get rid of these extra mailboxes?

You need to edit the user accounts in the Active Directory and remove your name from the MsExchDelegateListLink attribute.

1. Open Active Directory Users and Computers
2. Go to View menu and select Advanced Features
3. Open the user account that is showing in your mailbox (in the screenshot, my mailbox is in Mary's profile)
4. Open the Properties dialog
5. Click Attribute Editor tab
6. Locate MsExchDelegateListLink
7. Click Edit
8. Remove your name from the attribute
9. Close the dialogs

Keep FullAccess Mailboxes from being AutoMapped

Not everyone likes automapping of mailboxes, It's great for the end-user: the mailboxes they have permission to open are automatically added to their profile, avoiding the need to go into the profile and add the secondary mailbox manually. But not everyone wants to see the shared mailbox in their profile.

It's possible to give a user full access to a mailbox without automapping by adding –AutoMapping $False parameter to the Add-MailboxPermission cmdlet.

Add-MailboxPermission "shared-mailbox" -User "alias" -AccessRights FullAccess –AutoMapping $False
