Customize size limit of Exchange 2007 database

[Dwarner]

I have a PC at my office which is running on Windows server 2003. On this computer we use Exchange 2007 Standard Edition with database size limit of 50 GB. Actually we need to do some modification in this size. Do any of you have idea of doing that ? Please let me know. I need to do that urgently.

Well, you can do that easily but you need to workaround in registry. Heres how:-

• Start Registry Editor by typing regedit in the command prompt and Enter.
  
  
• Locate the following registry subkey:
  
  

  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\<SERVER NAME>\Private-<database GUID>

• You can get the GUID of a database by running the following command in the Exchange Management Shell: Get-MailboxDatabase -Identity "<server name>\<storage group name>\<database name>" | Format-Table Name, GUID
  
  
• If the Database Size Limit in GB DWORD exists for the subkey, change its value to the desired size in gigabytes.
  
  
• If the Database Size Limit in GB DWORD does not exist for the subkey, create a new DWORD with that name, and then set its value to the desired size in gigabytes.

Thats it.. You are done !!

The Exchange store process checks any database size limits periodically and dismounts a database when the size limit is reached. You can modify the database size limit by adding or changing a value in the registry.If you change the size limit of your Exchange databases, you may want to re-evaluate your Exchange database backup and restore plan. Specifically, if you increase the size limit of the Exchange databases, be sure to test your backup and recovery operations using the new database size limits to make sure that you can still meet your service level agreements.

To use the Exchange Management Shell to get mailbox database statistics, run the following command:

Get-LogonStatistics -Database <mailbox database name> | Format-List
