just around one hour ago, our entire emails system went down. Nobody could open Outlook (would hang) and the webmail service was the same. Throughout the day, it was constantly slow, very tempermental and evidently it took its toll and everything went down by the end of the day.
We;re running Exchange 2007. It does NOT have SP1. The disk space available for the database is 410GB and the free space on it is at 59GB! Now, around 6months ago we made changes to the registry so that it could accept a database size of 300GB. We're currently using 350GB from what it seems. I've gone into the registry and increased the limit to 400GB.
Nothing in the event viewer indicated anything about database size limit as far as I can see.
However, does this sound like it could have been the database size that caused the issue?
Also, there are so many deleted mailboxes and apparently only a defrag would get rid of them to free up space, but according to some experts this would take around 3 days?!
On the disk which holds the databases, we've created them so that it's not just one huge database file but we split into three database files. Is there a way of defraging each one separately so that it doesn't take 3days and going through this procedure without having to take down Exchange entirely?
Any solutions you propose would be much appreciated.
