Salle des ventes Forza Horizon 4

Is your game up-to-date? That quite often is the reason for it

I assume you have done all the Horizon Festival events? You have to do a certain number of the Festival events to unlock it....it's related to progression rather than Level number,

Can you access other online features? Ranked adventures? Clubs? Rivals? etc

"Why is the Auction House grayed out?

You may not have completed enough of the tutorial. Try going through more gameplay and make sure the Festival Playlist unlocks as well.

The privacy settings on your account may not be set up properly. Some privacy settings may interfere or reduce functionality in your gameplay experience. Your privacy settings may affect if you can receive gifts or use feature like the Auction House.

1. Go to https://account.xbox.com/Settings and ensure you haven't selected to block or restrict any privacy and online safety features.
   
2. Verify your privacy settings set to "Everyone" for "You can see and upload community creations" and "See other people's Xbox Live profiles (Xbox 360: Profile Viewing)"?
   
3. Double check the age setting for your account and make sure it's over 18 and not listed as a child account."
   

My guess it's one of the above, though given you are online, I'd suspect it's storyline related
