Microsoft 365 Windows 11 external user or guest user sign in

Consider the following situation: CompanyA has a Microsoft 365 tenant with licensed users. CompanyA has a business relationship with CompanyB which also has a Microsoft 365 tenant. All of CompanyB's Windows 11 Pro computers are Entra ID joined and Intune enrolled. All of CompanyB's users have Microsoft 365 Business Premium licenses.

An employee of CompanyA is stationed at CompanyB's office and needs to use one of CompanyB's computers as his primary computer.

How would a technician have to configure things so that CompanyA user can sign into CompanyB's Windows 11 Pro computer and work like normal? I've done some reading online but most of the articles focus on access to cloud resources, whether that be Microsoft Teams or Entra Enterprise Apps or similar resources. I haven't found an article touching on Windows 11 sign in.

  • Take this:

     

    Step 1: Enable Guest Access in Entra ID
    Add CompanyA User as a Guest: In CompanyB's Entra ID, add the employee from CompanyA as a guest user. This can be done through the Entra ID portal by navigating to Users > New guest user and entering the employee's email address.

    Assign Appropriate Roles: Ensure the guest user has the necessary roles and permissions to access the required resources.

    Step 2: Configure Intune Policies
    Create a Device Configuration Profile: In Intune, create a device configuration profile that allows guest users to sign in. Navigate to Devices > Configuration profiles > Create profile and select the appropriate settings.

    Assign the Profile to Devices: Assign the configuration profile to the Windows 11 Pro computers that the guest user will be using.

    Step 3: Set Up Windows 11 Pro Computer
    Enable Other User Login: Ensure that the Windows 11 Pro computer is set up to allow login from other users. This can be done by enabling the "Other user" option on the login screen. You can follow the steps outlined here to enable this option.

    Sign In with Guest Account: The employee from CompanyA can now sign in using their guest account credentials. They should see the "Other user" option on the login screen, where they can enter their Entra ID credentials.

    Step 4: Verify Access and Permissions
    Test Access: Have the employee from CompanyA sign in to the Windows 11 Pro computer and verify that they can access the necessary resources and applications.

    Adjust Permissions if Needed: If the employee encounters any access issues, review and adjust the permissions in Entra ID and Intune as needed.
