Exchange Server 2010 - Transport Service hanging due to large email in Outbok

Hello All

The Transport Service on our mail server sometimes hangs or just stops sending and receiving emails due to a user attempting to send a large email (in the most recent case, 2 emails each over 2 GB in size).   Although I have managed to solve the immediate issue, by using the following EMS command to identify large Outboxes:

Get-Mailbox | Get-MailboxFolderStatistics -FolderScope Outbox | where {$_.FolderSize -gt 1024000} |  ft Identity, ItemsInFolder, FolderSize –wrap

... I would welcome suggestions from the forum as to easier methods to track down the culprit.  I had initially thought that I could use message tracking but it seems you have to specify the mailbox of the user you wish to track, which of course we don't know at that stage.  I also tried looking at the submission queue but it seems that the message does not show until it has been completely submitted and also the queues are unavailable if the Transport service has crashed or is not running.

I'm sure that other Exchange users have encountered this problem - how have you resolved it?

Thanks

Glen

So you cant find the message in message tracker????  It should be able to pull messages from particular times of the day. In addition should provide a source and destination address.  You can set up your query to search for specific details of the message. Also be able to specify what mbx server to use in the search.

You can also try exmon

Let me know if that helps.

Hello HAJ2014

Unless I missing the obvious, Message Tracker requires you to specify the mailbox you wish to search and does not give options to search specific folders (i.e. Outbox) for messages above a certain size.

I just looked at EXMON and as you suggested, that could be a useful tool to help identify the likely culprit!

Thanks for your suggestions
