I just finished setting up Exchange 2010. We still have Exchange 2003 servers as well. Now my e-mail address policies are not working.
I have 40 e-mail address policies that assign e-mail addresses based on OU and now that is not working.
When I modify or create new policies I receive the following message:
You can't specify the recipient container because legacy servers are detected.
I use to be able to do this.
