Windows 10: Mail app problem

I added all my mail accounts and it synced up about 2000 emails from various address's. Is there a way to select all the mail to delete or do i have to check each individually. Ctr-A doesnt work to select all mail..

Mail App Notification

I have the Mail app for Windows 10 and have it setup for syncing and notifying me when I have new emails. When I click on the mail notification, the Mail app opens. However, the problem is that the Mail app doesn't work. To view the new email I have to
restart the Mail app. Then the Mail app works.

 

Microsoft Mail App repeatedly fails to download attachments

The problems mentioned have still not been resolved by Microsoft, the Mail App still will not consistently download Mail attachments including .jpg pictures, have a look at the feedback on the Mail App you will very quickly ascertain what a disaster this
App has turned out to be and Microsoft seem powerless or have shown no interest to resolve the bugs and problems within this Mail app. The same Mail App in Windows 8.1 worked perfectly, I would suggest to users of this Mail App to install Windows Live Mail
2012 which will work with Windows 10 and works perfectly in every respect.
