Adding Chat Contacts (external search issue)
When trying to add "Chat" contacts that exist externally using the desktop Teams app, the search process isn't consistent in showing the "Search [EMAILADDRESS] externally". If you click or tab outside of the box, the drop down disappears and doesn't come back even if you delete and retype the email address. I have to close the dialog and try again. Sometimes I have to hit enter on the keyboard to get the "Search [EMAILADDRESS] externally" option to show up because waiting doesn't produce anything. Sometimes hitting enter causes the drop down to go away and the search clear and nothing happens, requiring me to close the dialog and trying again.
