Exchange 2007: E-Mails not showing up, but have been delivered by E-Mail Security (SonicWall)

emailemail-serverexchangeexchange-2007sonicwall

I've a very strange problem:
SOME mails (I can't see a pattern) are not shown in our Outlook Exchange Accounts, but when I check the E-Mail Security Logs (we use a SonicWall), they seem to be delivered.

Does anyone have an idea where to begin with looking? I've controlled the settings, run all available updates for Exchange 2007 and checked the logs, but no results.

Thanks for any hint,
Joseph

You can use Exchange Management Console toolbox "Message Tracking" feature to check if the messages in question actually were delivered by Exchange into the store.

If they were, there is not much logged beyond this point - there is no log for storage operations in Exchange's default configuration. You might consider changing this via the Set-EventLogLevel Powershell Cmdlet and evaluate your event logs or use some 3rd party tool like ExInsight to get an idea about what your users are doing to the store so that messages "disappear".

Exchange 2007: How to tell which connections are Outlook Anywhere

Whilst you set-up Outlook Anywhere from the Exchange console, it's actually using the RPC proxy feature, which is separate to Exchange. Exchange doesn't actually care where the RPC connection comes from, whether its local or over http, as they all look the same when they get to Exchange, the RPC proxy and IIS handle the incoming traffic and forward it to Exchange.

To get some statistics on how many RPC users you have your going to have to look at the IIS logs. There is a good article here on using Log parser to get these kind of statistics.

For example, getting the RPC statistics would look like this:

logparser "SELECT cs-username, Count(*) AS RPCProxyHits from c:\windows\system32
\logfiles\w3svc1\ex*.log WHERE cs-uri-stem LIKE '%rpcproxy.dll%' AND cs-username IS NOT 
NULL GROUP BY cs-username ORDER BY RpcProxyHits Desc" -rtp:-1
