I am currently having a problem with my Exchange 2010 server. After an email is sent from the user it sits in the queue for around 30 minutes and then finally sends. Now for most this may not be a major problem but for my company it is a HUGE problem. This problem did not start until we changed our ISP a few months ago. Once we did that we started getting alot of emails sitting in queue that looked like this
