Hi Guys,

I've finally found the root cause of my transaction log problem few months ago, it seems that one of the mailbox in my exchange server storage group caused this problem.

Does anyone have any suggestion of what to do to diagnose it further or perform anything that is non disruptive as it is currently running in production ?

Thanks

Are you running regular backups on your exchange server?

I would say you need to be sure that the backup does not fail and if you only have a single tape unit be sure you manually load the second tape if the first one fills up. This will keep your transaction logs from filling up disk space...

Can you give more information on your comment above " it seems that one of the mailbox in my exchange server storage group caused this problem".

only this one particular mailbox which is used by the help desk team in production causing problem, whenever i moved it around to different storage group, it always grows the Transaction log until it is full and causing the whole mailbox in that particular storage group stops sending and receiving email.

Have you used Exmon to see why that particular mailbox is causing issues? It will help you determine if there is something going on... Also have a look at the other link.

My current solution that I had in mind is:

1. Export mailbox
2. Delete it
3. create same name mailbox
4. Import the mailbox (hopefully the Full access permission and the Send as will be the same).

And of course it must be done after office hours.

Well you could do that but I think (could be wrong) that the full access and send as permissions will need to be reapplied..That is if you are referring to exporting mail to .pst ..

That might be the fastest solution rather than troubleshooting why this particular mailbox is causing issues with the transaction logs.
