Disabling or removing a mailbox fails in an Exchange Server 2010 environment that has Office Communications Server 2007, Office Communications Server 2007 R2, or Lync Server 2010 deployed


Consider the following scenario. You have Microsoft Office Communications Server 2007, Microsoft Office Communications Server 2007 R2 or Microsoft Lync Server 2010 deployed in a Microsoft Exchange Server 2010 environment. You try to disable or remove a mailbox on an Exchange Server 2010 server. In this scenario, the operation fails, and you receive the following error message:

Action 'Disable' could not be performed on object 'FirstName, LastName'. 

FirstName, LastName
Active Directory operation failed on Server.domain.com. This error is not retriable. Additional information: Insufficient access rights to perform the operation. 
Active directory response: 00002098: SecErr: DSID-XXXXXXXX, problem 4003 (INSUFF_ACCESS_RIGHTS), data 0


This issue occurs because the Exchange Server 2010 Mailbox server cannot clear the value of the msRTCSIP-Line attribute. Therefore, access is denied when you try to disable or remove a mailbox.


To resolve this issue, install the following update rollup:

2645995 Description of Update Rollup 1 for Exchange Server 2010 Service Pack 2


To work around this issue, manually clear the value from the msRTCSIP-Line attribute by using the Active Directory Service Interfaces Editor (ADSI Edit).

Note This is also known as AdsiEdit.msc.


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
