Correcting errors in Mail on OSX

This article provides a solution to issues you may be having with Mail on OSX after a software update. Please follow the instructions below to resolve the issue. 

In newer versions of OSX, your email settings can be lost after a software update, or when you have iCloud sync enabled.  
Follow the instructions below to resolve the issue.


Important:  Mail has a setting called "Automatically manage connection settings".  Please ensure this is disabled.  It will result in the server locking you out, as the settings Apple use are incorrect.
