I continue to have problems with Windows Live mail even after uninstalling and reinstalling

Due to sending issues with my aol and gmail accounts, I uninstalled and reinstalled Windows Live Mail.  Gmail was set up ok but aol will not.  I keep getting a message indicating that the aol server has unexpectedly terminated the connection.

My individual aol account is working fine.

I have set the incoming server to imap 993 and the outgoing to smtp 587.  Why do I continue to have problems.  I have a Gateway NE 722 laptop with Windows 8.1 Pro.

Thanking you for any assistance you can give me.
