Without a third party application, you cannot do this "automatically".


You've also got some misunderstandings how OSTs work. If you connect a
profile to another server, a new OST will be created.


I think you need to take a step back and take a look at your solution
from a fresh perspective. Examine NeverFail and DoubleTake and
MessageOne (there are other players in this space, but those are
probably the big names).

Subject: [exchangelist] Secondary exchange server and automatic spooling 



I have set up two exchange servers, one as primary and one as backup.
The two are far apart across the Internet (many hundreds of miles
apart).  There is no Active Directory connection between them, i.e. they
are not in the same forest, no "trust relationships" between them etc.,
and they do not have the same AD DOMAIN name and no VPN between them.
This is intentional, for reasons I won't go into here to avoid clouding
the question. 


The primary mailserver and backup mailserver are both configured with
the same user accounts.  The intent is that if the primary fails
disastrously for a prolonged period, users will switch their profiles
manually to the backup server and will have send and receive and OWA
capability (not just storage for received emails but no send or OWA as
with a secondary MX mailserver).  Of course, the historical content will
not be visible immediately but that will be in the OST files so in
cached mode, should get sync'd up. 


The question is:  when the primary server comes back on line, how do we
ensure that all the email that was received on the secondary server,
automatically gets spooled to the primary?  is there a way of "flushing"
or "spooling" this data from the backup server to the primary server? 


best regards
