we keep getting thyis warning that has just started the past few days. Unable to update Mailbox SD in the DS. Mailbox Guid: bc1cebae-005a-4e46-83e8-66ab53553f75. Error Code 0x8004010f i saw this KB article: http://support.microsoft.com/default.aspx/kb/555433i downlaoded the AD find tool BUT it says 0 results Probably because the mailbox is already gone. How do i fix this?

Either the mail box is gone or is in disconnected state. In both the cases it will be tough as msExchMailboxGUID has to be cheked now one by one.Check this but will have to do some manual work http://support.microsoft.com/default.aspx?scid=kb;en-us;322308Raj
