I have never done an offline defrag of an Exchange 2007 (or higher) database. It isn't something that Microsoft recommends, involves extensive downtime and isn't risk free.
As Exchange 2007 supports multiple databases, just create a new database, move all the mailboxes to the new database and drop the original. Zero downtime, zero risk.

Otherwise no other maintenance needs to be done - Exchange looks after itself. As long as you are doing regular backups then you should be fine.

You don't have to do any maintenance. By default the Online Maintenance will run every night at 1 a.m. To change the defaults follow: http://technet.microsoft.com/en-us/library/bb629590(v=exchg.80).aspx

As previously stated, generally online maintenance should be able to handle the day-to-day. However, if you check the Event Logs and it doesn't look like maintenance, such as the online defrag, is every completing then you may need to take the database offline. For example an Offline Defrag.

I had to do this recently for a 2007 database that was 40% white space. It shrunk down big time as you can imagine.

Exchange databases need maintenance. This maintenance defragments the databases, reindexes the databases and performs other tasks necessary for long-term sustainability of the databases.
