    It could be due to many reasons. one reason, some one is spamming from outside or inside 2- Your users have large attachments stored in their mail box.

        Hi,

        Do a message tracking for your mailbox server in check how many email transactions are happening. This is for spam.

        If someone has mounted pst file into their mailbox using outlook.

        check mailbox sizes (if no restriction is in place)

        other thoughts are there as well.. but lets try these one first.
        Thanks & Regards

            Hi,

            Open message tracking tool, leave sender and recipient blank, input your exchange server name, select the time frame and then track for that 2 hour period.

            also check in queue viewer if you have any queues build up
            Thanks & Regards

              There is no queue build up.
              what am I looking for in the message tracking?

              Thanks,

                From Sembee's site, make sure you aren't an open relay. What antivirus/antispam are you running - check it's logs as well.

                  Even if you were an open relay, it wouldn't cause database bloat. An Open Relay bounces off Exchange, it doesn't get delivered to the store.

                  Primary cause would be an email loop.

                  An offline defrag isn't going to help either, particularly if it has just happened. The content may well not be marked as white space in the database yet, so wouldn't be released by an offline defrag. You need to look for event ID 1221 overnight to see how much space you will get back.

                    You are correct. I did offline defrag and it didnt really help. Luckily I got exchange 07 ready to roll into productions..
                    we are start migrating database to 07 and keep monitor to see if database still grow outages.

                    what is "Primary cause would be an email loop" what might cause that?

                      Automatic Forwarding enabled. User is forwarding email to a personal account, the personal account is full or there is an attachment that is too large, it bounces back, the Exchange server forwards it out again and round and round it goes.

                        Very interesting... Before this issue.. I have users contacting me why their mail is forwarding to the external address that never been use and their inbox is hug....
                        I will keep an eye on that individual account.

                        I wish there is a way to prevent client set the rule to forward their email.

                        Thanks,

                          Allowing automatic forwarding of email to an external account is NOT enabled by default on Exchange. Therefore it has been changed on the server.

                          The configuration is outlined here:
                          http://support.microsoft.com/kb/266166

                          On Exchange 2007 and higher it is on the Remote Domains setting.
