My friend who is Online, appears Offline in Microsoft Flight Simulator

Had this same issue where we were all online in xbox live but some of us showed as disconnected in MSFS2020.

We fixed this by making sure all of us as friends had the same date and time settings (including daylight settings and timezone) in Windows (right click on your clock and choose "adjust date and time").

You may all need to then SYNC your time under the "syncronise your clock settings" to ensure you all have the same time.

Note: We had to all close MSFS2020 and reopen once our clocks were in sync to then allow us to connect.

Hope that helps lots of users as it took us ages to fix and couldn't find an answer anywhere.

I found out why this was happening to me. You need to have created a party in Xbox Live to be able to have your friend in a group on MSFS2020

Log into xbox.com

go to xbox profile

go to xbox privacy settings.

change settings to desired choice.

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.
9-Your Xbox will automatically update the Microsoft Flight Simulator installation in the background.

I really do hope microsoft makes a flight simulator for xbox one. Making a offline signal player ( 50 or mission's ) mode and a online multi-player mode. I would definitly buy that.
