Hi All, I've just migrated from Domino to Exchange 2007 SP3 on a Hyper-V client running Windows Server 2008 R2, with 8 GB of RAM, 500GB static Hard Disk space (not partitioned) running about 250 mailboxes all at 1GB, and a dedicated LAN Port running through a gigabit core switch. The problem I have is that the message queue is taking a while to clear, causing delays of up to 30 minutes on mail delivery. I've determined that it is not a cpu or RAM issue as these are not maxing out, and my network port isn't being overloaded so I'm leaning toward the problem being messages getting from the queue to the Information Store, however I haven't found any good articles on how to confirm or troubleshoot this (If that really is the issue). Please assist.
