When looking at my CAS server it is Pinned at 100% CPU and taking about 2GB memory. Exchange imap.4.exe is taking about 70-90%

I am on Exchange 2010 SP2 (14.02.0247.005)

Restart the IMAP service - that will fix it.
however, turning up the diagnostics on the IMAP service might show you who is borking the service.

Check the OS version on any iPhones and iPads that connect to Exchange. iOS 6.1 is know to cause such issues, so if any of your devices are running this version upgrade them to the most current iOS.

When all else fails, read the book!
