Hello, I am sure you've all heard this issue before. I came in this morning and our Exchange server says it has reached its database size of 25 GB. I have had users begin to clean our their mailboxes to free up some space on the database. What other procedures should I follow to retrieve my database size, extend the size and get my STORE back up and running properly.

25GB means you have already SP2 running on Exchange 2003 standard edition. You need to modify registry values, check below similar thread and the links given in it.... http://social.technet.microsoft.com/Forums/en-US/exchangesvravailabilityandisasterrecovery/thread/3236ea04-eafd-471d-aed7-b95c19a56850/ Amit Tank | MVP - Exchange | MCITP:EMA MCSA:M | http://ExchangeShare.WordPress.com
