Exchange 2007 mail.que keeps growing

Hi,

I have a mail.que on Exchange 2007 SP1 that keeps growing (2Gb) overnight even when send/receive connectors are disabled. I have stopped the transport service, deleted the mail que and restarted but the problem persists.

if left, the server disables mail traffic based on Back Pressure Buckets exceeding the configured limits (which are std). Exchange has been performing fine until 36hrs ago.

No messages appear in the que.

Most solutions call for the mail que to be deleted but this has not solved my problem. Any help would greatly be appreciated.

Thanks

Alistair

Hello,

Turns out it was an odd DNS issues. Disables Ethernet controller, re-enabled and reran fix network after setting same ip address. ODD!

IF you have any query please revert back us.

Thanks.

Unfortunately this did not solve the issue.

I have since discovered that the problem started when a user sent a 1Gb message. There were no global transport size limits set in Exchange 2007.

It almost seems that the message is stuck somewhere in Exchange but I cant find where. The workstation has successfully sent the message and it has been deleted from the users mailbox. It never appears in the exchange queue.

As soon as the Exchange Transport Service is started, the mail.que file starts growing causing Back Pressure issues.

My problem is best described by this post:

I used Exmon to identify high CPU and Bytes Out on a mailbox. Deleting and re-creating the mailbox solved the problem.

Thanks
