it can use some different web based email clients like yahoo and a few others .
this site might help Mail app for Windows - Windows Help
As far as I can tell, the Share charm can only connect to Share-enabled apps, and there are very few of them. Maybe MS only planned to use it with Metro apps. I understand Win 10 has made Share more friendly.
Hi there. WLM is a Win32/64 desktop program whereas Charms is in the Modern UI environment. Never the twain shall meet. Modern Store apps work in conjunction of one another, whereas Win32/64 apps do not. That's the beauty of the system. e.g. As you know if I want to share a screenshot I simply press Share Charm, an email draft opens, not the whole program interface.
Let me demonstrate. I highlight all this. Then press Charms > Share > Start typing name > Pick name > Press Send or Alt/S. Done.
Yes I realized that would make it easier for people to send me screenshots when they have questions. But very few are using Mail.
I was hoping with what seems like increased integration between metro and desktop in 8.1 that I could connect the two.
