Getting error code 0x80072746

I upgraded to Windows 10, and set up the Mail app. Some e-mail show up, but when I try to sync it to get new e-mails, I get error code 0x80072746. Anyone know what this is, and how to fix it?

This just shows how useless Microsoft engineers really are, the apps trouble shooter for win 8 does not work with win 10 , surely you should know that, how about giving us a decent & actual answer for once,

why does this code 0x80072746 come up on your new useless mail client supplied on win 10, I can download mail but when I try to send it I get this code when it syncs, like others I want an answer to why it is happening, not a link to some standard thing
that does not work with the new win 10, & if you don't know why say so & admit you new email client is **** & recommend that every body use Mozill Thunderbird in the first place, why don't u people just answer a question for once in your lives, someone must
know why this error code appears & what it means, for gods sake tell us.
