LibreOffice Writer mail merge to email wont connect to my smtp server

I have been using 4.2.6 on Windows XP and the mail merge to email works fine.

I now have windows 10 with 5.0.2 x64 after setting up email connection details I test and get this :

LibreOffice could not connect to the outgoing mail server. Check your system’s settings and the settings in LibreOffice. Check the server name, the port and the secure connections settings

<class ‘RuntimeError’>: No SSL support included in this Python, traceback follows
C:\Program Files\LibreOffice 5\program\python-core-3.3.3\lib\smtplib.py:663 in function starttls() [raise RuntimeError(“No SSL support included in this Python”)]
C:\Program Files\LibreOffice 5\program\mailmerge.py:120 in function connect() [self.server.starttls()]

Any ideas, Windows 10 problem perhaps ?

Thank you.
