Some mailboxes on Microsoft Exchange 2010 cannot be deleted via Exchange Management Console. Following error is displayed:

Active Directory operation failed on <domain controller>. This error is not retriable. Additional information: Access is Denied. Active directory response: 00000005: SecErr: DSID-033520B4, problem 4003 (INSUFF_ACCESS_RIGHTS), data 0

The affected mailboxes seem to be those that were moved during Exchange Upgrades from Exchange 2003 > 2007 > 2010.


To resolve the issue:

  • Open Active Directory Users and Computers
  • Enable ViewAdvanced Features
  • Double click on the affected user and switch to Security tab
  • Click on Advanced button
  • Check Include permissions from this object's parent box and click OK in both open dialogs
