Hi there.
I'm curious if SP1 fixes the problem large AD environments have with users being unable to modify their own DLs and Delegates? I understand that 2007 RTM Topology Generator like 2003 SP2 only picks a max of 10 DCs/GCs for DSAccess. Outlook uses that list for GAL lookups, DL and Delegate modification, etc.
When you Exchange servers centralized in one domain (we do) and have greater than 10 AD domains (we do), you can get random domains being unable to use these features. Hard-coding a GC in the registry for Outlook is pretty much of out of the question as a "fix".
There is major lack of support in the 3rd party land for DL modification (and none for delegate modification that I know of). Quest rolled their ActiveGroups product into another one (ActiveRoles, which has too many features we do not need nor want to pay for.), and Ianami's SmartDL product isn't yet supported on 2007. Having 1 product to choose from kind of sucks when Exchange is supposed to be able to do this natively. :) I'd rather not have to pay for anything to 'fix' it.
I'm also curious if Outlook (wrong blog I guess) is going to use RODC or ROGC for GAL lookups then fail back to a writebale DC/GC for DL/Delegate modification, or if Exchange will only tell it about writeable servers.
Hoping for good news!!! Thank you.
