Exchange 2003 database size

The database size limit for Exchange 2003 standard is 16GB, however SP2 for Exchange 2003 allows you to remove that limit. The default size for priv.edb after installing SP2 for Exchange 2003 is 18GB this can easily be changed for database sizes upto 75GB per database.

The steps below explain how to increase the 18GB limit by editing the registry. Edit the registry at your own risk, I will not accept any responsibility if you run into problems.

  1. On the Exchange 2003 server, run regedit
  2. Navigate to the following registry key

    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeIS\Server name\Private-Mailbox Store GUID

  3.  Create a new DWORD entry called “Database Size Limit in GB”
  4.  Change from Hexidecimal to Decimal and enter the value of the size in GB that you wish the maximum DB size to be.
  5. Exit from the registry editor
  6. You should now either restart the Information Store or dismount and mount the store in question.

The maximum database size for the priv.edb should have now been increased to the value you set in the new DWORD

Ex2010 – Ex2003

During as SBS2003 migration to SBS2011, while decommissioning the source server (SBS2003) before Exchange 2003 can be removed you will have to remove the routing group connector from Exchange 2003 and Exchange 2010. You can use the Exchange System Manager to remove the 2003 to 2010 connector. To remove the connector from the destination server 2010 to 2003 you will use the Exchange Management Shell using the below command.

Remove-RoutingGroupConnector -Identity “Exchange Administrative Group (FYDIBOHF23SPDLT)\Exchange Routing Group (DWBGZMFD01QNBJR)\DestinationServer to SourceServer” -DomainController DestinationServer.LocalDomain.local

Make sure you change the following first;

DestinationServer = name of new SBS 2011 Server

SourceServer = name of old SBS 2003 Server

LocalDomain.local = name of the local domain


The use of this code is done at your own risk.
