Hi @Pete Jaeger , if I understand correctly you're trying to add a printer but are getting this error? This error is usually caused by attempting to sign in with an unsupported identity provider, but you can fix this by adding one: https://learn.microsoft.com/en-us/azure/active-directory/external-identities/external-identities-overview
Please let me know if this fixes your problem. If so, please verify this solution so other users may reference it.
If you have any questions please let me know.
Thank you,
James
