My Microsoft account is not working for Azure

Hi RogerSchlueter-7899,

Thank you for posting your query on Microsoft Q&A.  

As per our understanding, you are trying to use your personal Microsoft Account (MSA) to create or manage resources (like an Azure SQL Database) in Azure. However, you're seeing this error:

Selected user account does not exist in tenant 'Microsoft Services' and cannot access the application 'c44b4083-3bb0-49c1-b47d-974e53cbdf3c' in that tenant. The account needs to be added as an external user in the tenant first.

This usually happens because your Microsoft account only exists in Microsoft's default tenant and isn't part of the Azure AD tenant where you are trying to access resources. Since your account isn't added to that tenant, Azure can't recognize or authorize it, so the action is blocked
 

Please follow the steps below:

Check if you are in the correct directory

1. Go to the Azure Portal.
2. In the top-right corner, click your profile icon.
3. Select "Switch Directory".
4. Choose the directory (tenant) where your subscription or resources exist.

Add your Microsoft account to the target Azure AD tenant

1. Ask an administrator of the Azure tenant (where you want to work) to:

• Go to Azure Active Directory > Users > New guest user.
  • Enter your Microsoft email address.
  • Click Invite.
  1. Accept the invitation from your email inbox.

Please refer to: Add guest users to your directory

Assign proper permissions

In the Azure portal, go to Subscriptions.

1. Select the subscription where you need access.
2. Click Access Control (IAM) > Add role assignment.
3. Choose a role like Contributor or SQL DB Contributor depending on your need.
4. Add your invited guest user and click Save.

Please refer to: Assign roles to users in Azure

 Sign out and re-sign in

1. After accepting the invite, go back to portal.azure.com.
2. Sign out, then sign back in.
3. Make sure you're now using the tenant you were invited to (not Microsoft Services).

Now, go to SQL Databases (or whichever resource you were trying to access) and try again. The error should no longer appear.
