2 accounts invited to preview program, neither has access.

Sorry to hear it. However an invitation does not guarantee access to the program. Also, currently the program is at capacity and they are not sending out new invitations.

Please keep an eye on your Live messages though as when they do start sending out invites again they will let people know.

Hey, l Kevin OG l! It looks like your account has only been invited to the preview program. I've got you the proper role to access the
Preview Program Support forums. Since you seem to have the most recent preview update, it's likely that there is another account on your console that is fully enrolled in the
program and has your console in the preview. Thanks for posting!

Hi there,

If you used to be a member of the preview program, you should still have access to the Xbox Preview Dashboard app, or the registration app. If you have neither of these, you are probably not in the preview program.

You cannot be invited over the support forums. You will need a friend who is already in the preview program to invite you.

You will need to try and ask for further assistance in the private preview forums area. If you get an error message, you must wait for a support staff member to give you access.

I also was sent an invite to the Xbox One Preview program and even called Xbox One Support and was told that my account was fine and to post on here. I had two friends send me a invite to the Preview Program and I haven't received the invite yet since last
week. What do I need to do to be given access to the preview program?

Hi,

If you didn't accept the invite then there's a chance you weren't added to the preview program list. Normally you could wait for a support agent to grant you access to the private preview forums, and then ask there to be re-invited. However, the preview
program has now reached near capacity, and it is now highly unlikely that you will be able to join the preview program.

Thanks!
