Why doesn't the mail arrive in the user's mailbox.
We have a Barracuda spam firewall that forwards the desired external e-mail to Exchange Server but the e-mail does not arrive in the users' mailboxes. There is no rhyme nor reason to the pattern. All internal mail does succesfully arrive. Where is the issue?

Do you manage the firewall? You would need to look at forwarding,blocking and filtering rules there.
There should be logs that show messages transfered.
It would be helpful to use a personal outside aemail account to troubleshoot with. Send a message to your self then wtch the firewal, and logs between firewall and mail system.
Returned messages to your personal mail acoount will give things to work with too.

Passed the firewall. Passed the spam appliance. Lost somewhere in Exchange.
And only external messages but not all external messages. There is no pattern to external messages.

There has to be a pattern, some common cause. What do you see in the Exchange logs for the missing messages. They have to go somewhere.
here is a primer for Exchange logging.
