I have mail version Version 17.9126.21535.0

My main email (I have other accounts in the same program) doesn't work, update and crashes the whole mail program/app when I try to sync it. The other emails seem to update okay, and I can even send emails from them, but I need my main email address where most of my emails come and go from. Everytime I click on it, it crashes the mail and sometimes, the mail just crashes for no reason.

(It's also not working on my phone, but there I can receive emails, just not send them and that is an app issue that began before this app issue.)

Please help!

Also, I don't want to uninstall it, I don't know how to save my contacts outside of the email program.
