Increasing the store size after SP2
From Mike's Wiki
Increasing the store size after SP2
- Figure out how big you can make your store on your server based on hard drive size
- Browse to HKLM\ SYSTEM\ CurrentControlSet\ Services\ MSExchangeIS\ {SERVER NAME}\ Private-013e2e46-2cd7-4a8e-bfec-0e4652b94b00
- Create a REG_DWORD called "Database Size Limit in GB" and enter the DECIMAL value (ie switch the input to DECIMAL) in GB you want to use from 1-75
Restart the Exchange Store service
