As other's have stated your transaction logs get automatically deleted
when the information store is backed up successfully.

Circular logging resuses existing transaction logs creating a total of 5
transaction logs with a total of 5 MB each in a round robin use.  So
when log 5 files up it goes back and reuses log 1.  The problem with
this is that if you have a database failure you will only be able to
restore the database to the point of the last successful backup
effectively losing whatever was in the database after the backup.  If
circular logging is turned off you can restore your database and then
using the transaction logs "replay" until you get the database back to
where it was just before the crash.  If you have the space I strongly
suggest you do not turn on circular logging.

Not to be nit picky but it means you are not backing it up _correctly_
As Doug mentions, a correct on-line exchange backup will purge the logs
on completion of the backup process.

Transaction logs are automatically deleted upon successful backup of
exchange. If your getting a large collection of transaction logs, that
means you are not backing up Exchange.

Subject: [ActiveDir] OT: Exchange Transaction logs

Just had a couple of questions about a couple things I can't seem to get
a straight answer for. 

Is there a recommended length of time to hold on to Exchange transaction
logs? 

Is there any reason to keep transaction logs around any further back
than specified in the checkpoint file?

Is it typical to enable circular logging, or does this somehow get you
into some issues if a disaster does happen?

As always, THANKS for your advice/comments
