Exchance 2013 on Server 2012 - Exchange receives emails then delays them internally for at least 30 mins, most often hours. I'm intermediate skillset on Exchange and a novice with 2013.
Server.sub.domain.com is our server. This was received at 02:23 and wasn't delivered to the mailbox until 04:07. The server is a new build, only about 2 months old, with a very small number of users and low utilization. It's not a hardware or resource issue, I believe it's simple configuration that I've missed somewhere.
We're having internal delivery problems as well, but I believe that's Outlook cache related, rather than Exchange. Exchange is running on the server and we have Hyper-V running a single workstation VM for off-site users.
