Duplicate folders are created after a mailbox move in Exchange Server 2013 Enterprise


View products that this article applies to.

Symptoms

Duplicate folders are created in Microsoft Exchange Server 2013 after you move a mailbox that has large or corrupted properties or after you move a mailbox by using the -IgnoreRuleLimitErrors switch.

For example, you might see Task, Task1, Contacts, Contacts1, and so on. Also, the Folder Type value may be "User Created."

Cause

This problem occurs because mailbox folder properties are removed if a property error for the Inbox folder occurs during the move. Such errors prevent migration of the default folder references for the Inbox. After migration, the default folders are re-created.
