You can deploy applications via Intune. See my posting Deploying an MSIX application via Intune for more details. While I was working for that article I received the error message: Your IT administrator did not make any apps available to you. I will share my troubleshooting steps with you.

Description Picture
You get the message 'Your IT administrator did not make any apps available to you.'
In the overview please check that:
  • The ownership is set to Corporate
  • The primary user and enrolled by user are the same user
  • Compliance is compliant
MDM Authority is intune.
Check that the user has at least an intune licenses.
And use the troubleshooter. In this case, it is obvious that the user has not the correct groups assigned.
Sometimes it is just a matter of being patient.
