All Inboxes

There's a button at the top of the inbox that filters for unread emails - at least, that's what it does on my email. It looks like this:

Try clicking on that, especially if it is blue . I had this problem and couldn't figure it out until I clicked on this by accident.

Hi Dorelle,

Thank you for participating in the Apple Support Communities. If you are having issues with your emails, here are a few steps that may be useful:

1. Restart your device to see if the issue is still there: Shut down or restart your Mac - Apple Support

2. Confirm that your device is using the most recent software to rule out the older one: Update macOS on Mac - Apple Support

3. Try the steps here to see if they help: Troubleshoot email problems in Mail on Mac - Apple Support

4. Contact Apple Support here if you need further support: Contact - Official Apple Support

Have a great day.

Hello Dorelle,

If you feel that is the case, you're welcome to leave feedback so it gets to the appropriate team here: Product Feedback - Apple

Otherwise, you'll want to take the last step and reach out to Apple directly so they can look into it further with you: Get Support

Thanks, and kind regards.
