Slow Send and Receive with Outlook 2010 and IMAP

When using Outlook 2010 and IMAP, users may experience slow sending and receiving or are not able to send and receive at all. This can be caused by Outlook pulling folder count for sub folders. This can especially affect users who have multiple subfolders with multiple emails in them.
