SYMPTOMS
When you attempt to change the mailbox rights of a mailbox through the Users and Computers Microsoft Management Console (MMC) in Active Directory, you may receive the following error message:

A catastrophic failure has happened - can't assign permissions.



CAUSE
After a mailbox is created, the security descriptor for that mailbox moves from Active Directory to the information store. When a user wants to adjust a mailbox right, the user needs an access control entry (ACE) that grants the correct permissions to do that. In a scenario in which one user does not create a second user mailbox, the information store returns an &quot;access denied&quot; response, which is translated by Active Directory as a catastrophic failure.



STATUS
This behavior is by design.
