Scenario
A licensed guest user is trying to access enterprise applications via the My Apps portal.
Observed behavior
The system denies access, displaying an error message regarding account permissions and organization company settings.
Before you start

Ensure you have administrator privileges in your organization's directory, as resolving this issue requires checking tenant-level guest access policies.

Solution 1Recommended

Verify and Update Guest Account Access Settings

Check if guest access has been revoked or incorrectly configured within the organization's settings.

Guest user errors on the My Apps page are typically caused by misconfigured organization policies or application permissions that block external users from authenticating correctly, even if they hold a valid license.

1
Log into the admin portal

Access the Microsoft Entra admin center (formerly Azure AD) using your company administrator credentials.

2
Locate the guest user

Navigate to 'Users' > 'All users' and search for the affected guest account to ensure their status is currently active.

3
Check external collaboration settings

Go to 'External Identities' > 'External collaboration settings' to verify that guest access has not been restricted or revoked by a recent policy change.

4
Review enterprise applications permissions

Check the specific application the user is trying to access under 'Enterprise applications' to ensure guest users have the appropriate permissions to sign in.

Frequently Asked Questions

Why does a licensed guest user still get an access error?

This usually occurs if the organization's policies restrict guest access to certain enterprise applications, or if there is a delay in permission propagation after the license was assigned.

Can a standard user or the guest fix this My Apps error themselves?

No. Resolving guest account permissions and organization policy settings requires administrative access to the company's directory. A company administrator must intervene.

Where can administrators check guest access settings?

Administrators can check and modify guest user access policies in the Microsoft Entra admin center under the 'External Identities' and 'Users' management sections.
