tennant account

Question

Selected user account does not exist in tenant 'dorsetcrew.com' and cannot access the application '8c59ead7-d703-4a27-9e55-c96a0054c8d2' in that tenant. The account needs to be added as an external user in the tenant first. Please use a different account.

Thank you for your post!

Error Message:

From your error message, it looks like you might be running into a similar problem as stated in our Error AADSTS50020 - User account from identity provider does not exist in tenant documentation, specifically relating to Cause 4: Guest user wasn't invited.

To make sure this is the issue, look for the User account and Identity provider values in the error message, to ensure that the values match the expected combination. For example, did you sign in by using the tenant specific account (i.e. user@domain.onmicrosoft.com), or did you sign in using a user that's not a part of the tenant? If you signed in with a user that isn't a part of the tenant, you'll have to invite them as a Guest user prior to signing in with that account. For more info - Add a guest user and send an invitation.

I hope this helps!

If you have any other questions, please let me know.
Thank you for your time and patience throughout this issue.
