Oh. I don't have a better answer for you.
In most places, Exchange 2007 made you use Universal groups, but in some places it let you slide. Exchange 2010 doesn't let you slide in most places. If all your DCs are GCs then I don't see what the big deal is? You already taken any associated replication hit. Having a group be universal simplifies logic in lots of places in Exchange that otherwise have to be aware of HOW and WHERE to expand a group. It could be a real PITA in Exchange 2000 and 2003.

All our DCs are GCs if that helps. I'm just trying to understand this a bit better, there's going to be questions to be answered when I go to a meeting and ask that we change all ours DLs to Universal "because Exchange 2010 is making us" :) Richard ________________________________ From: bounce-9271364-8066...@lyris.sunbelt-software.com [bounce-9271364-8066...@lyris.sunbelt-software.com] on behalf of Michael B.

It's only just started biting us on the arse, which is why I thought it might be something specific to do with Exchange 2010, especially surrounding RBAC.

This first started in E2K7 IIRC. From: Sobey, Richard A [mailto:r.so...@imperial.ac.uk] Sent: 07 February 2011 17:35 To: MS-Exchange Admin Issues Subject: Universal vs Global groups in Exchange 2010 Can someone remind me why Exchange 2010 [SP1] is so picky about groups being configured as Universal vs Global? Unless groups are Universal, we are now finding that Outlook users cannot modify DL membership. We're a single domain/single forest/Exchange 2007/2010 mixed environment. Googling this topic only brings up the fix, not the why. Cheers!
