Exchange 2003 DB dismounted due to being full

I had an Exchange 2003 server dismount today due to the DB being full..  I have a journaling mailbox that has grown to be huge.  I had the mail archiver services stopped due to performance issues.  This resulted in the mailbox growing extremely large.  I turned on the service which results in all emails being read, archived to a different server's MSSQL DB and then deleted from the journaling mailbox.  Is that the only thing I need to do?  This is essentially deleting thousands and thousands of emails.

Whatever you need to do to reduce space is required. The database will not mount if DATA or LOGS are full.

The archiver service purges emails from the journaling mailbox once archived.  When it's done the mailbox will drop from 5.7 GBs to almost 0.  So..  Do I need to run mailbox management or anything after it's done deleting the emails?

Once it deletes the emails, you'll be ok.

What is the current limit of your database?  Out of the box the limit is one thing, but after a registry tweak, you can max out at 75gb.

In my experience, you'll still be able to mount the database even if it's over 75gb, but it will dismount at seemingly random intervals (to get your attention)

No you can simply mount the database back once the free space is restored. Also make sure that your logs are not full as well.

FocIS,

I already tweaked the registry to allow 75GBs.  The DB is mounted for now and deleting MANY emails.

Thanks.

If too many emails, it may be faster/easier to delete the journaling account and recreate it.

If you have exmerge installed, you can also exmerge with archive to remove from the source on that mailbox.

If you're doing it by hand, at least use shift-delete to bypass the deleted items folder :)

The 75gb limit is a soft limit btw. Therefore if you get dismounted because you have hit the limit, just restart the information store service and the database will remount (until 5am the next day).
