Very slow Exchange 2007

Posted on 2013-05-17
Last Modified: 2013-06-04
I have en SBS 2008 server with Exchange 2007. When people send us email it takes between 3-5 minutes before it apears in both Outlook 2010 (cachemode) and OWA.
Earlier the emails popped up immediately...

There is no anti spam on the server itselfs, but we have mailfiltering hosted.

The problem is there on both external and internal mails, so I dont think the problem is the mailfilter.

Exchange 2007 is latest version with all hotfixes installed.

I really dont know where to look... anyone that can help ?
What can I do to restore the performance on the exchange server ???

do you have any kind of firewall on your network which is filtering traffic ?

We only have our WAN firewall CISCO ASA 5510, but it does not filtering traffic.

The ASA device does filter SMTP traffic. It is notorious for causing odd email delivery issues.
It is so common that Microsoft have a KB article on the process:

I found the problem....
Journaling was enabled, and the mailbox somehow got deleted, so I had 21.000 email in the mail queues.
After disabling the journaling, and cleaning the queues, everything is working perfekt again.
