Here is my scenario:
New Forest: xyz.local (Exchange 2010, Windows 2008 R2 domain controller)
Old Forest: abc.local (Exchange 2003, Windows 2003 domain controller)
Shared SMTP domain (for example): contoso1.com
Trust: There is a full trust established between forests.
My old exchange organization is authoritative for “contoso1.com" and the user uses one of the SMTP domain “[email protected]” as their primary email address. I want to migrate users from old forest to new forest. During the migration phase users will use contoso.com as their primary email address in the New Forest too.
To resolve the logical boundary limitation of Exchange. This is my plan:
1) Configure contoso.com to be non-authoritative on both new and old exchange org.
2) Create connector in Old Exchange org to relay unresolved user’s email with “contoso.com” SMTP namespace to Hub transport server in New Forest.
3) Create connector in New Exchange org to relay unresolved user’s email with “contoso.com” SMTP namespace to Bridgehead server in Old Forest.
4) Decrease the hop count to minimum to avoid message loop.
thoughts please!
