Xbox receiving message notifications, but not an actual message in the inbox.

Hello ULT Lite,

Thank you for posting on the Xbox forums. We recommend
removing the account from the console and downloading it back. Also, do you receive any messages through the Xbox app on your phone or computer? Be sure to let us know the results!

from whom do you get the messages? from friends or from xbox itself? the messages from xbox are no longer in the complete overview but in a sub-item in the messages area

Try performing a hard reset EXACTLY like this. Hold the power button on the console for 8 seconds or until the power shuts down completely. Unplug the power cord from the back of the console for 5 minutes. Plug the power cord back in and restart
the console.

There are no longer friend requests on Xbox One. People may follow you but if you receive messages you can do the following...

A) specify from whom you can receive messages

B) specify if you want on-screen notifications for messages, in general.

You can't (AFAIK) specify whose messages you get on-screen notifications for, though.

So, you can either turn off notifications and then just check messages inbox periodically for those from friends (or from LFG, when you're expecting them), or disable messages from everyone but friends. Either
should solve what you're after, but with different trade-offs.

Hey there, the only thing I can think of is if you've had any recent friends requests? Sometimes I check the request through my friends list which leaves the notification in my inbox. I thought I had a ghost notification for a while until I went through
all my messages and found a random friends request I had rejected through my friends list.

If you're inbox is completely empty though, I think official support might need to look into it.
