Usually, there comes a state in
Exchange server 2010 where Exchange server mailbox database status shows as
'Failed and Suspended'. It indicates that there is any possible issue in
mailbox database which needs to be rectified by an Exchange admin. But, the
replication service doesn’t sometimes check whether this error has been
resolved or not, so as an administrator you need to figure out this issue using
shell command before the mailbox database replica can be restored to again a
healthy state.
