Windows 10 Mail attachments

[Simon1975]

I have read many threads on this but none seem to share my problem.
In File Explorer, when I right click a file (eg a PDF) and click send to> Mail recipient, the Mail app does not open. Instead it opens windows live mail. I have set the new Mail app to default but this makes no difference. windows live mail opens but will not connect to my email.
I have then same problem when sending directly from another program such as Adobe reader or my Accounting program.

I think that you will discover that you will need a true Win32 Application in order to get the "Send-To" mail recipient to work correctly.
The "Mail" app within Windows 10 is something called a UWP App (Universal Windows Platform) and as a consequence, seems to only work with other UWP Apps.
IF you open that same PDF with Microsoft Edge (the default PDF viewer for Windows 10) and then use the "Share" icon in the top right corner, and choose "Mail"

You'll find that it will call the "Mail" app and work as expected.
That's an example of a UWP app making an API call to another UWP app.

there is an easier way. Go to your control panel and open [Default programs].
click on " set your default programs " and choose on the left side in the list your default program for EMAIL and
click on {set this program as default} ....
