Hello Everyone,

The c: drive ran out of space ealier today which cause us some email issues.  Once I freed up space, email starting flowing again, but at a slower rate.  I  am looking at the queue in system administrator and see email in the "messages pending submission" folder.  I have never seen that before.  The other thing that I see is the transaction logs are starting to mount up.  I am getting a new log every minute.  I have checked the event view and not seeing any errors.  I have plenty of space on the c drive, so I am not sure what is going on.  Can anyone help??

The c: drive filled up because there were to many log files.  I am notiicing that the database has not grown much today maybe 200 megs so far, but have have 746 log files for today.  Does that seem normal?  How many log files should I be seeing in a day?

The amount of log files generated is determined by the amount of mail flow. The more mail flow, the more log files.
Yes the amount of log files seems fine. My mail server has 1700 log files for today, and the backup completed at 5am this morning. The bigger concern is why are your logs not being flushed. Is your backup program set to delete committed logs? If it is set to flush committed logs, has the backup been running?
Exchange server will not remove the logs by default (unless you enable circular logging), it will keep receiving/sending mail and creating the log files until it runs out of room
Double check your backup strategy.


Thanks for you help...My backup software flushed all the transaction logs.  We are running out of space on the D:\ and I guess I never really paid attention to the amount of transaction logs.
