Cannot send mail using Windows 8 mail or WP8 mail client.  Works from web client, so not an account issue.

 

Same for multiple users I have checked everyone has same issue.

Tried various devices and connection options i.e. home internet, work internet, 3G etc

 

Issue is with Microsoft, I tried logging an issue but received no help.

 

Where top from here or is outlook.com simply an unsupported product?
