Why is Microsoft Flight Simulator ignoring the offline content?

Hello Afruzu how are you?

My name is Ezequiel I'm an Independent Consultant.

What appears when you try to connect your internet on your Xbox? Are there any error codes or warnings?

Yes you can play this game offline, however you need to download content from it so you can play offline.

1-Open "My Games & Apps" on the Xbox console by choosing the "My Games & Apps" tile on the Xbox Dashboard or by opening the Xbox Guide and choosing the "My Games & Apps" option.
2-Find Microsoft Flight Simulator in the "Games" section of "My Games & Apps". Note: If you are installing or pre-installing Microsoft Flight Simulator, the game will immediately appear in the "Games" section and you can do this during installation.
3-Open the Microsoft Flight Simulator "More Options" menu by highlighting Microsoft Flight Simulator under "My Games & Apps" and pressing the "Menu" button on your Xbox controller.
4-In the Microsoft Flight Simulator "More options" menu, navigate to the "Manage games and add-ons" option and open it.
5-On the Microsoft Flight Simulator "Manage Games and Add-ons" screen, highlight and open "Microsoft Flight Simulator" on the right side of the screen.
In the "Microsoft Flight Simulator" menu, navigate to and select the "Manage installation to (storage device)" option.
7-On the Microsoft Flight Simulator "Manage Installation" screen, navigate to the "World - offline mode" add-on in the Microsoft Flight Simulator base game. Note: Selecting the "World - Offline Mode" add-on will install it, while unchecking it will either uninstall the add-on or prevent it from being installed.
8-After making the changes, navigate and select the "Save Changes" option on the right side of the screen.

Hello Hugo,

Hope your day is well. You mentioned you want to transfer Microsoft Flight Simulator to Steam. According to the Microsoft Flight Simulator FAQ, "content is tied to the platform you are playing on—if you purchase a DLC on Steam, you cannot transfer it to the Microsoft Store version and vice-versa."

I hope this answers your question.

It's not possible to play MS Flight Simulator completely offline and download the the entire game. The reason is because it's simply too big.

The total size of Microsoft Flight Simulator on the server is absolutely massive! It's estimated to be around 2 petabytes, which is equivalent to 2,000 terabytes or 2 million gigabytes.

Flight Simulator X isn't. That is an old game. However Microsoft Flight Simulator is.
