You would think this would be simple, but...
(Note, I rarely use the Windows Mail App for sending email).
When I write a new message and start to type the email address, a list of matching addresses pops up. The problem is one of those addresses is invalid, I want to delete it, but I can't even find out where it is stored.
When I click on the little people icon in the Mail App, it shows a few frequently used addresses, but the bad one isn't there. When I click on Browse Contacts, it opens the People App, but says "We couldn't find email address for you contacts". If I open the People App from the Start Menu, it show a hand full of contacts that don't have email addresses.
How do I find and delete this bad address?
