Windows 10: Discovered Bug in Windows 10 Mail App - Phantom Unread Messages Icon in Taskbar & Start Menu

I've discovered whats causing the phantom unread messages icon to show unread emails in the taskbar and start menu.


Steps to reproduce:


1. New unread emails sitting in the Inbox (or any folder).

2. Click on the unread email, then quickly right-click.

3. Before the app recognizes the email as being opened and read, click "Delete".

4. Close down mail app. "Unread mail" icon numbers in task bar will flash, disappear, then immediately reappear.

5. Phantom Unread mail numbers will remain in the mail icon (and mail app tile in the start menu) , even when new emails come in, they will not be updated or accurate.



The only way to get rid of it is to uninstall the whole mail and calendar app with the PowerShell, then reboot the computer, and reinstall for the Windows Store. All which is a pain in the a...

Windows 10 Mail Indicates Phantom Unread Message


I am having a problem with Windows 10 Mail in which the icon in my task bar, and the icon in the start menu, indicates that there is one (1) unread message available. However, all messages have been retrieved and read.

I had this problem before, quite some time ago, and reported it here in another thread. At that time, the solution offered solved my problem. However, this time, the solution is not working. I can't seem to get rid of the phantom unread email count.

Screenshot taken from another computer still have Mail app in the system.........

 

Taskbar Mail icon continues to show unread mail count after emails are read

I also have this bug for a long time. Sometimes reading new mail resets the icon counter, but sometimes it keep showing as unread ((in both Taskbar and Start menu, while in the program itself there aren't unread messages at all). To clear it manually you
can click that icon 2-3 times: launched Mail app is minimized and restored and the icon counter resets.
