Backup ground : Our company merging with 2 other companies..situation 3 domains & three exchange setups

Now we are DomainA.com, DomainB.com, DomainC.com, the external mails sent should have domain as DomainB.com for users from all domains.

DomainA using Exch 2007, DomainB using Exch 2003 & Exch 2010, DomainC is using 2007.

The mails sent through external to domainB should route internally to proper domainA users, DomainB user & DomainC users, we are not migrating these users to one domain at the moment.

How do we achieve this............any help would be valuable...

Hi Leif,

Thanks this link is useful, any other alternative without creating contacts.

Also, can you suggest any way to share GAL across domain (without using Identity manager)
