Increase Exchange 2003 Standard Database Size

With Sp2, Microsoft Exchange 2003 Server database size had been increased to 18GB. Well nowadays a Bluray disc has 40GB of storage, even 18GB is not a big number anymore. However you may need a bigger space, as the Exchange server 2003 standard edition supports up to 75GB of data.

To increase the size of the database;

First enter "regedit" on the run box on the start menu.

Then find these subkey

• HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\\Private-GUID
• HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\\Public-GUID

The GUID at the end of the subkey is a long folder packed with numbers and letters.

Enter a new DWORD Value for both of the subkeys. In the "New Value #1" box, type "Database Size Limit in GB", click OK. Right click the DWORD , click modify and enter the amount you wish to be your max database size. Don't forget to enter an integer from 1 to 75. 75GB sounds just good.

Close the regedit screen. Open up the Run box, enter "cmd". At the command prompt type;

• net stop msexchangeis

After the service stops successfuly, type;

• net start msexchangeis

All done! You can verify your success by taking a look at the event viewer console. Under "Application" tab, look for the event with the ID 1216.
