Although this also involves Exchange, I hope someone can help me with the
following scenario as soon as possible:
Same Company
Two Separate Forests
Two Separate Domains
Two-way transitive trust
One Exchange Org with Admin Group One as Forest A
and Admin Group Two as Forest B
Full ability to see and administer each other's AD and Exchange, if
necessary
Forest A recently migrated from Exchange 5.5 to Exchange 2003 and AD 2003.
Forest B wants to do the same.
When Forest A decommissioned its Exchange 5.5 server, its new Exchange 2003
server could no longer see Forest B's Exchange 5.5 server (which is Win2k
OS), and any new users added to Forest A do not appear in the Global Address
Book used by Forest B, and which was in the past shared by both forests - as
a result, Forest B can send no emails to new users in Forest A.
In addition, the 5.5 server in Forest B can no longer be seen or
administered by Forest A, even though there is an ADC between them.
Microsoft says that because Exchange 5.5 does not use AD and Exchange 2003
does, there will no longer be any communication between the 5.5 server and
the 2003 server until Forest B migrates or upgrades to AD 2003 and Exchange
2003. Microsoft also said that if Forest A brings back the 5.5 server for
the sake of Forest B's upgrade or migration, that it still would not work.
Forest B has a new AD 2003 server that it wants to promote, and demote the
existing AD 2000 server.
After establishing an ADC between forests, Forest B has a new Exchange 2003
server that it wants to introduce to its domain. Forest B is also
considering an inplace upgrade of its existing 5.5 server.
The issue is the preservation and move of the mailboxes without having to
PST them manually. If an Exchange 2003 environment cannot see an Exchange
5.5 server, how can we move the mailboxes?
Sorry for being long-winded... thanks for any help you can give
