Windows Live Mail

Version: 2012

Build: 16.4.3528.0331

When I go to send a message I get the following error:

An unknown error has occurred.

Server: 'mail.mymts.net'

Windows Live Mail Error ID: 0x8007007A

Protocol: SMTP

Port: 587

Secure (SSL): yes

Tasks:

send 2 messages using Mymts (d........) failed

Move sent messages to 'sent items' folder on Mymts (d........) failed

Check for new messages on Mymts (d.........) completed

Send 2 messages using 'old mts pop don't delete' failed

I tried the solution of "Repairing all Windows Essentials program" through my Control Panel but it didn't fix the problem.

Any help would be appreciated
