Hi,
We're trying to integrate Exchange free busy between two organisations, so far we have:
- Two way domain trust between domains, domain1.lan and domain2.lan
- Running GALSYNC (via FIM) to sync contacts between the domains
- Added AvailabilityAddressSpace for the SMTP domain for each domain
- User@domain1.lan can successfully get free busy/calendar information from user@domain2.lan and vice versa
- Users can successfully open mailboxes from across the forest
I'm just trying to clarify how this actually works, is this correct?
User@domain1.lan tries to open User@domain2.lan calendar. The availability service on exch.domain1.lan looks at the primary SMTP address of user@domain2.lan (or does it use some other attribue on the mail contact?), then looks up autodiscover.domain2.lan to point it to the availability service of domain2?
We are using shared SMTP space between the domains. In the event that user@domain2.lan changes their email to user@domain1.lan but remains on the domain2 exch server, how does the availability service know which Exchange server to use?
