Failed to create the mailbox; insufficient permissions, ESE error, or memory error can cause the problem. Try creating mailbox again or review error and event log.


This Error event indicates that a mailbox for the user account specified in the event description could not be created. This event may occur when moving the mailbox from one mailbox database to another mailbox database. One or more of the following conditions may occur.

  • The mailbox for this user already exists in the mailbox tombstone table.

  • The user account specified in the event description was deleted but the changes were not replicated to all the domain controllers in Active Directory.

  • There are logical corruptions in the database.


You may also see an Error event 1022 in the Application log.

User Action

To resolve this error, follow these steps:

  • If this error occurred during a move mailbox operation, make sure that the move was successful. If not, try to move the mailbox again. Make sure both the source and target mailbox database stores are in Mounted state.

  • If the mailbox was previously deleted, and it is still under retention period, reconnect the mailbox instead of recreating it. By default, the retention period for deleted mailboxes on Microsoft® Exchange Server 2007 is 30 days. You can see a list of disconnected mailboxes in Disconnected Mailbox container under Recipient Configuration in the Exchange Management Console.

  • Review other related Error and Warning events in the Application log. These related events may help you find the root cause of this error.
