It seems since I've implemented Exchange 2010 (2007 co-existance for now as well, until mailboxes are all moved) I've been getting the following error on some of my 2003GC's. Active Directory failed to create an index for the following attribute. Attribute identifier: 2218634146 Attribute name: msExchMailboxAuditEnable Can someone help me with a fix?

Running Exchange 2010 Standard Sp1 Ru1, Win 2008 R2. Someone? please?

Hi Ryan, Please do as below: Remove the containerized index from the attribute cited in the 1464 and 1136 events, either by unchecking the containerized index checkbox in Active Directory Schema Manager, or by reducing the value of the searchflags attribute by "2" using LDP.EXE or ADSIEDIT.MSC. Or you could refer to below link: http://technet.microsoft.com/en-us/library/dd364609(WS.10).aspx Regards! Gavin
