I use Windows 10 Photo Gallery Live to generate an email.  It goes through the process of taking the photos selected in PG Live, reduces the images to a smaller size, and creates an email.  I then go to Windows Live Mail to Send it.  It ends up automatically in the Outbox and when attempting to resend it causes an error.

An unknown error has occurred.

Server: 'smtp-server.nc.rr.com'
Windows Live Mail Error ID: 0x8007007A
Protocol: SMTP
Port: 25
Secure(SSL): No

If I use Windows Live Mail to create the email first and ATTACH photos, I can then send the email without an error.  I prefer that the photos be in the body of the email which used to work pre-Windows 10 so that the receiver gets to see the larger image rather than a thumbnail.

Is there a fix for this??
