Already follow steps from http://support.microsoft.com/kb/912375/but still cannot got the 75GB message 1215from event viewer, do anyone know why? thanks

Have you restarted the Information Store service since the registry update? How long has it been since you did this update? Also, do you have SP2 installed to Exchange 2003?

Clarify: You have exchange 2003 standard SP2, and you want to increase database size to 75GB, right? The database size limit registry keys are read when the database mounts (not when the service starts up), and when each limit check task runs ---------- Database Size Limit Configuration and Management You need to dis/remount the store, and let keys been read. So it can generate the application log

Yes, already restarted the Information Store. Around ten minutes. Yes, already have SP2 installed to Exchange 2003

Yes, already installed SP2; I want to increase database size to 75G. How to dis/remout the store ? I just stop & restart information store, but not work, no application log can found about database increase to 75G.

dismount and remount store: ESM->Administrative Groups->Server->right-click your "Mailbox Store", dismount and mount store

I just know my server version is SBS 2003 SP2, so how to check servce pack of exchange ? Thanks!!!

Check version: 1. Go to C:\Program Files\Exchsrvr\Bin 2. Right-click Store.exe, select Properties 3. Version tab 4. Check the comment, it shows SP version

I found it's SP1, so I just to download exchange 2003 SP2 for my server SBS 2003 SP2, right ? Any step to install this SP2 ? need to stop exchange ? can user be use the email during update ? Thanks !!!

Installing the Exchange service pack will take exchange offline and make it unavailable to any user. You should plan to do this in non-peek hours. Also, the 75GB changes dont apply in sp1, so install sp2 then double-check the registry settings to ensure they weren't reset by the service pack. then your limit should be increased to 75 like you configured.

Hi, Its pretty simple to install SP2. Yes, it may require reboot during installation and mails service will not be available so you need to schedule it with proper downtime. This will explain you with list of new features A First Look at Exchange 2003 SP2 http://www.msexchange.org/tutorials/First-Look-Exchange-2003-SP2.html

Thanksall who reply me. I had success to install SP2 & change size limit to 75Gb. By the way, no need to reboot the server during install SP2; just cannot use email service.

Nice to hear that

I found most of error from event viewer after upgrade to SP2, so can I recove back to SP1 ? Thanks!!!

You should resolve the errors one at a time (likely all related anyway). Don't uninstall the service pack. It's been out for years and is very stable. But yes, you can always remove service packs by going to Add/Remove Programs.

But I cannot found any exchange service pack 2 in add/remove program from control panel, do you know why?

There is a checkbox at the top of the add/remove window that says "show updates". see here
