For a couple of weeks, every time I start Windows Live Mail, a window pops up telling me to protect my account info by signing in again. Signing in again doesn't stop that pop-up, so I ignore it.

For the past few days, when I exit my email, a window pops up asking me if I want to send the mail in my Outbox. I don't have an Outbox. Clicking Yes or No makes no difference. The window keeps popping up.

Just now, I lost all my contacts. Clicking on Contacts shows nothing but blank space. When I start to type someone's name in the To part of the email, it doesn't fill in the rest of the name. I'll have to reload my contacts from my backups.

Jerry,
I also use Windows Live Mail and have had no problems since switching to WIN 10. This past week, I started getting the dialog box about mail in my Outbox. There is none - but clicking "Yes" closes the box and let's me proceed to shut-down. Not sure why you're having problems with your Contacts. So far, I've not encountered that problem. It's possible that the way you upgraded to WIN 10 may be causing the problem. My PC had WIN 8 on it when I bought it. I went through and ensured that all apps and drivers were current. Then, I upgraded to WIN 8.1 (required to upgrade to 10). Once 8.1 was installed and stable, I upgraded to WIN 10. So far, no problems. Wish there was an emogi for crossed fingers!

Wouldn't it be nice if computers worked right? :D
