[ActiveDir] [ActiveDIR] OT: Windows 2003 Forest Functional Level 2 while running Exchange 2000

> Hello,

> I was wondering if anyone had any experience with changing their
> Windows 2003 Forest Functional Level to 2 (Windows Server forest
> level) while running Exchange 2000 (post SP3)? I've found some
> documentation stating the Exchange 2000 recipient update service does
> not replicate changes successfully in forest functional level 2 in a
> 2003 Active Directory. From what I've read the best practice is to
> leave the Forest Functional Level  on 0 (mixed level forest) until the
> Exchange 2000 server has been migrated to Exchange 2003. Any input is
> much appreciated.
