how do i set my gmail inbox to show unread mail

From the page cited by resondent Jeff Yang7 below, however, the problem also occurs with Exchange servers, so I suspect it is a bug in Outlook.

I don't know how the 'unread' count is generated, so I can't speculate more precisely on the cause. The pervasiveness of the problem suggests that it is either a bug inheritted by Outlook from version to version, perhaps in its engagement with the IMAP protocol and/or its own bookkeeping, or it is due to erroneous IMAP information from Gmail. I see it in both Outlook 20, on separate Windows 10 machines. Where the problem likely lies: Gmail's webmail interfaced doesn't show any unread messages, so I think that the bug is in Outlook. How can I force a correction to the 'Unread' indicator in the email folder pane?

Symptoms in a nutshell: The email folder pane shows that the 'All Mail' folder have 2 unread messages, but when click that folder and choose 'Unread' from the top of the message list, there are no unread messages. I initially posted this question to a vendor site, but my luck there is hit and miss.
