Problem stated last night, seemingly just after a marathon session upgrading from Windows 8.1 to Windows 10. Did not notice until just now because I am able to receive emails (but not Send) and am able tp send and receive Skype IM messages
Emails go into outbox and transfigure into bold italic but do not send. Get Send/Receive error message, but no code number although think it might be 0x800CCC0B
Have already tried this.
