Exchange Server is FULL - need help

Our Exchange 2003 Server is filling up and I need a solution fast! Its running an old HP Proliant DL380 with 2 drives.

There is a C: drive with a 34 gig partition with 7 gig free, and the D: drive (the problem) with a 101 gig partition and only a little over 1 gig free.

The Windows 2003 Server is also running active directory, DNS, and is a domain controller. A few months ago we did bring up a 2008 Server as a primary DC, DNS and running AD.

1) What can I do to to reduce the size?
2) Buy a new server? And how to migrate email stores?
3) What about public folders?

Here is screenshots of the problem:

Watch Question

My first question is are you backing up this server regularly and flushing the Exchange logs? Only a full backup will flush those logs.
See this if you cannot perform a full backup for some reason: http://support.microsoft.com/kb/240145

Second, how much room (whitespace) do you have in the mailstores, the thinking being you can do an offline defrag of the mailstores to reduce the footprint and gain some physical space.

Let's start there ad then talk about your other question on what to do long term.

Hi TheHappyTech,

I would suggest you to conenct a higher capacity hard drive, Dismount the store in non-business hours --- Move the requied database files --- change the database target in the store properties & mount the store again.

Here is the link which will guide you through out the process.

Also do check for the white space on the database, I would suggest you to create a new Information store. If you are using an enterprise editon. Dismount the old store -- Move the database to the new location --- Then in the new store properties target the old database which is now on the new location and mount it again. You will now come up with a new fresh information store.

If there is white space more then 25 % of database size then the database needs to be offline defragmented. (It can only be done during non-business hours as it take 4GB/1Hr rate.)

Hi,

You can resolve this issue in multiple ways.

Method 1
Insert a new hard disk and move the Exchange database that disk.
This you need to dismount your database and perform this activity.
http://www.petri.co.il/move_exchange_stores_to_a_different_disk.htm

Method 2
Insert a new hard disk and move backup and other folder showing in the D:\driveto new hard disk (move apart from exchnage database).
This you no need to dismount the Exchange databse.

Perform the normal backup first, this will purge the committed logfile.
Then perform incremental backup end of every day. This will purge that day committed logfile

Defrag the Exchange database if it having more white spaces. It will give more free spaces in the database also increase the performance of the database.

The Backup and Defrag are optional but recommended.

Method 3
Check how much white spaces available in the Exchange mailbox database.
Check the event viewer you get the event 1221, it will show you how much white space available in the database. If more than 25% of white space available in the database that recommended to do Exchange offline defrag.  This require down time, in general  4GB  database  required 1hour to defrag,  also it will depend on your Exchange server performance.  Apart from this you must need  110% of free disk space in same drive or other drive ie(if your database size is 50GB you need 60GB free space )

Method 4
If you are planned to buy a new server then purchase the server and install the OS and make the server as member server by attaching the server to the domain.
Install Exchange2003 server to the member server then move the mail box database and public folder database to the new server.

Above all the solution the simple solution is Method 2

Thanks.
