Why doesn't my Microsoft mail app sync?

Microsoft mail app does not sync

Hi, after the last update, mail app on my surface does NOT sync at all.
What can I do?

Mod edit: Personal e-mail removed...

Re: Microsoft mail app does not sync

Which update are you referring to? Are you running Windows 8.1 or Windows 10 Technical Preview?
