If the two companies are in the same Exchange organization and same Active Directory forest, then this sorts itself out.
If the two companies are in separate organizations, and therefore separate forests, you'll need either a third-party tool to synchronize the directories (or enter them manually if they're not too big), or you'll need a front-end sendmail or some such host with an alias table to route the mail to the appropriate Exchange organization. Avaliable options I'm aware of for replicating directories between organizations: 1. HP LDAP Directory Synchronization Utility (LDSU) http://h18005.www1.hp.com/services/messaging/mg_ldap.html 2. Microsoft Identity and Integration Server http://www.microsoft.com/miis 3. MIIS GAL Sync tool (limited but free) 4. SimpleSync http://www.cps-systems.com/ 5. MS Mail Dirsync (unsupported by Microsoft, but is supposed to work) 6. Active Directory Connector (in interorganizational mode) 7.

We used some kind of SMTP connector... If we only have less that 1000 users all over those exchange servers, is a bridghead server really needed ? The bandwith is very fast between all sites and there is not a lot of users.... - Because we will have 2 AD Domains with different exchange org, when eMail arrive to the wrong server in one of the 2 different AD/exchange org, we were intending to use the " FORWARD ALL UNRESOLVED ADDRESS TO " features in the SMTP Virtual Server... Is it ok ? Is there anyway to have the calendering between exchange in 2 seperate AD and exchange org ?? This is a temporary situation as Company A's AD, domain, exchange org will be migrated to the new AD/Exchange infrastructure....
