Mass change of Exchange 2003 mailbox rights

Jun 19, 2008 at 1:31 PM
Looking into a single user rights to all the mailboxes but i get the error below

Unable to cast COM object of type 'System.__ComObject' to interface type 'CDOEXM.IExchangeMailbox'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{25150F51-5734-11D2-A593-00C04F990D8A}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)). Verify that this user has an accessible mailbox

Can anyone help?
