I use Windows Live Mail in conjunction with Windows 10.  Generally no problems.

Today, two messages I tried to send via my Astound (Wave) account did not go; they remain in my outbox.  I click each separate message and click send/receive; nothing happens.

The tech folks at Astound won’t help, since they do not support Microsoft products.  I can’t find anything on the MS website that directly addresses the matter.

Can anyone offer suggestions on how to get the Outbox messages on their way?
