We have recently moved away from POP3 mail to our own Echange 2003 Sever. I built the server about 3 weeks ago. It is using 2 80 gig disks on a Promise IDE controller in a mirrored array. The install went well. I then installed Outlook 2003 on all PC's
To roll this out slowly, I setup Outlook on all PC's to use the respective mailboxes on the exchange server and also added a POP3 account to their profiles to continue to download their mail from our ISP's POP3 server. So the situation was this: my MX record still pointed to our ISP's mail server, and my users PC's were downloading their mail to their Exchange mailboxs by using Outlook.
One other note, I installed Trend Client/Server/Messaging Suite for SMB on the Exchange Server. This includes eManager Spam filtering.
Everything was running well, my edb file was about 12gig and my nightly online defrags were reporting about 2 Meg of free space.
Then, last weekend I changed my MX record to point ot my Exchange server and I started receiving mail right away. All was good, and it seemd t work well. The users came in Tuesday morning, and things were working.
I then noticed that the nightly online defrags were reportin huge amonts of free space (about 2 gig) in the priv1.edb file. So, I did an offline defrag and saw the EDB file shrink by about 2 gig! This was good. I then noticed the next day that the free space was back to 1800 MB of free space????
The only things that changed since the 2 meg of free space reports are that my Exchange server is handling SPAM and it is managing the incoming mail.
Any body have any idea's
