Thank you for posting this question in Microsoft Q&A.
For Windows 10, the option is only available as a local admin/local account. Regular users cannot join their accounts to Azure AD.
Other possibilities and steps to try:
- The device is already joined to on-premises Active Directory. If this is the case, you will not get the Azure AD join option because you would need to perform Hybrid Azure AD join in that case using either of the following methods:
- Configure hybrid Azure Active Directory join for federated domains
- [Configure hybrid Azure Active Directory join for managed domains](https://learn.microsoft.com/en-us/azure/active-directory/devices/hybrid-azuread-join-managed-domains) You can try using below commands to join Azure AD and check the status:
- Configure hybrid Azure Active Directory join for federated domains
- DsRegCmd /join
- DsRegCmd /status
- They can create a new offline profile and log in with that profile to join to Azure AD
- Make sure they are not using the Home edition. If they are, they will need to upgrade the edition since the Home edition cannot be joined to Azure AD
