Symptoms

When you try to sign in to Dynamics 365 customer engagement apps or use Dynamics 365 App for Outlook, you receive one of the following errors:

• You are not part of this organization. Please contact your administrator.

• You are not a member of this organization
  You (<username>) do not belong to the organization <organization name>. Verify the organization name and try to sign in again.

• Your account has been disabled
  Your account (<username>) is disabled, and you no longer have the privilege to access this organization. Contact your Microsoft Dynamics CRM Online administrator for assistance.

• no instances found for this user ID
  You have signed in with a user ID that cannot log into Dynamics 365. Contact your administrator to make sure that you have a valid Dynamics 365 user account.

• Invalid User Authorization
  The user authentication passed to the platform is not valid.

Cause

The error can occur if you aren't a member of the security group that's associated with the Dynamics 365 environment.

Resolution

To solve this issue, contact your Dynamics 365 administrator to add you to the security group that's associated with the Dynamics 365 environment you're trying to access.

If you're a Dynamics 365 administrator, navigate to the Power Platform admin center. Select the environment that the user can't access and then select Edit. If the Security group field is populated, ensure the user is a member of that group. If the security group is managed in Microsoft 365, you can add the user to the group from the Users area or the Groups area in the Microsoft 365 portal. For more information about how to add a security role in Power Platform admin center, see Assign a security role to a user.

If you still can't access Dynamics 365 customer engagement apps, try Microsoft Support and Recovery Assistant to troubleshoot sign-in issues.
