We have a 5,000 user 2003 A/D environment, using Exchange 2007 for email. Our clients are a mix of Outlook versions, from 2002 to 2010. We're trying to get our clients updated, but it's not a quick process.
We are in the process of replacing our DC's with 2008R2. Our plan is that when the last 2003 DC is replaced, we will upgrade our domain to native mode 2008R2.
One of our admins had "heard" some very vague information that going to A/D Native mode 2008R2 will cause problems with the Outlook 2002/XP clients.
I've done some searching, as well as posting on the server areas, but so far I've not found much info.
Is anyone running Outlook 2002/XP clients in a native mode 2008R2 A/D environment?
Any information would be appreciated.
