I installed the latest windows 10 update yesterday and when I went to check my mail there was no account.  I created my account as directed, but it does not receive mail. I have tried syncing, changing my password from my email password to Microsoft password, that didn't help.

I thought I could uninstall the mail app and reinstall it  from the store app but can't seem to delete it either.  I really need help as my email is very important to my work.
