Missing emails - any ideas?
I've received a complaint from a couple of users that emails they were sent from an external contact have not appeared in their mailbox. I've checked and they can receive emails from other external accounts, but when i check with our messagelabs track and trace system the emails do appear to have arrived at our mail servers. We have two exchange 2003 servers (both SP2) - one main mail server at head office which has our SMTP internet connector to Messagelabs, and a second one at the branch office where these two users are based. I've checked the message queues in System manager and there is no backlog or bottleneck and exchange appears to be running fine on both servers and i've not (yet) had any messages from other users saying they are missing expected emails. The emails appear to have attachments of around 13MB each, but they limits for send and receive on both users mailboxes are set to maximum of 50MB, so its not being blocked on this account. Also, the connector between the sites has no restriction on the size of attachments, so it's not being blocked because of that either. I've asked them to get their client to send all three of us a message with no attachments at the same time to see if i can receive it (and if i do, whether they do or do not receive it). If this comes through, i will then ask the client to send the original email with attachment to all three of us and again check if any of us receive it. Is there anywhere else i should be checking to track this problem down?

attempt to track the message in ESM, (under tools). this should report from messagelabs all the way to the user.it could also be the mailbox store in the branch office does infact have a size limit even though you have adjusted it elsewhere
