old email addresses

Thank you for updating me HA.111

Here is the step to remove that old email address.

Start typing an email address into the “To” field. As soon as you see the old email address being recommended as one of the potential candidates, use the down arrow key to scroll through the list of suggestions. Once you highlight the old email address, type
the delete key. In many cases, this will actually remove the entry not only from the current list of suggestions but from future suggestions as well. You may even find that as you mouse over the drop-down list the highlighted item will have an “x” to explicitly
allow you to delete it.

Just do this step and your good to go.

Continue to have an escellent day HA.111

Emails delete when searching inbox for old emails

All of a sudden when I have searched for an email using the sender's name in the "search" field using the Mail app in Windows 10, when the email I am looking for come up and I click on it, all other emails before the email I was looking for start populating
in the email list and then they all go away. To provide the best example I can to describe what I'm talking about, the old emails come up and then one by one they delete from the list very quickly until the entire inbox is empty. When I then click on the inbox
tab my current emails reappear so my emails are not actually deleting, but they appear to delete when I search for an old email. Hope this makes sense. If not, I'm sorry. I don't know how else to describe this.
