 outlook software send/receive fail, encryption type unsupported error

Solution

10/23/2018 TLS 1.0 was permanently disabled at our host. TLS 1.0 reached official end of life June 2018.
So if you run outlook software (or other email softwares) on a Windows 7 computer, your ability to send/receive stopped. You may even get an error that the encryption type is not supported.

Always perform a backup before attempting repairs. If you are unfamiliar with the methods below, consult a professional.

Why did send/receive stop working, I have outlook set to use SSL, not TLS?
Despite labeling in outlook software, SSL in settings actually makes use of TLS protocol 1.0, there has been a Windows update for Windows 7 that enables TLS 1.1 & 1.2, but pre-existing softwares didn't get the registry modifications to make use of them instead of 1.0 .
Windows 10 and updated versions of Windows 8 make full use of TLS 1.1 & 1.2 automatically.

These steps are for outlook 2007 (& 2003) in Windows 7 64-bit, other variations should be similar.
