hello, this is a case of two companies merging so there are two completely separate Windows 2008 Domains/Forests (domain1.com and domain2.com) each with its own Exchange 2010 email (again domain1.com and domain2.com). We are keeping the existing servers & windows domains and want a single email domain for everyone. The new (additional) email domain is newdomain.com. We want:
1. each user to have an additional newdomain.com email address (i know how to do that and route email with connectors so that's not an issue)
2. single GAL that will include all users
3. sharing of Calendar free/busy information and delegation privileges across the organization.
I need insight in regards to steps 2 & 3 above. What's the best way to do that?
