4. Click Initiate Failback to being the failback process.
Exchange Note: If you deslected any mail stores during your failover configuration,
you may see a message during failback about potential errors
(unpaired mail stores). This message can be disregarded.
If you created any new mail stores on the target after failover, they will
not be failed back.
Mail sent to public folders during failback may be routed to the target
server after Exchange is shut down, which will result in mail being
stuck in the queue. Make sure mail is not sent to public folders until
the failback process is complete.
If you close the Application Manager during failback, you may have to
manually run the post_restore.bat file which starts the Exchange
services and updates public folders on the source.
If your source is an Exchange 2007 CCR, LCR, or SCR cluster, after
failback the CCR, LCR, or SCR replication will need to be manually
reseeded after verifying Exchange is functioning properly. For
information about this process, see Microsoft TechNet Article
.
In a like-named cluster environment with more than one DNS server,
there may be a delay contacting the source after failback. The DNS
server used by the source cluster is updated on failback to point back
to the source server. However, if the Application Manager is running
on a machine that uses a different DNS server, it may not recognize
the change until the next DNS zone refresh.
