SYMPTOMS
The Move Server Wizard doesn't finish, and you receive the following error message:

There were unexpected duplicate collisions with objects encountered in the site the server attempted to join. Please resolve these duplicates and rerun the Move Server Wizard.

The application event log also registers an accompanying warning with the following description:

The object caused a collision with an object in the site the server attempted to join.



CAUSE
When you run the Move Server Wizard, if a Recipient container that is being moved has the same name as a mailbox in the site where the server is being moved to, a "collision" occurs during the mapping phase when the directory name duplicates are actually detected. The collision causes the Move Server operation to end.



WORKAROUND
Remove either the mailbox or container that has the same name as the one being moved.

A point to remember: If you are removing a container, all objects in that container are removed also. In that case, it may be easier to remove one mailbox and then recreate it later rather than removing the container with the same name and have all objects in that container be removed also.



STATUS
Microsoft has confirmed that this is a problem in Microsoft Exchange Server, version 5.5.
