ClientSecretCredential authentification failed (occurs just with “Application Permission”)

Open

This error occurs when the client secret of the application (in Entra ID) has expired (max. 24 month)

Go to your “Entra ID” search for our ROOMZ application and create a new client secret, make sure to copy the value key. Navigate back to the ROOMZ portal and under setup > booking system > settings insert the new key.

Code: ErrorInvalidUser / Error no access / access denied

If you have this or similar errors its common that your application or user don’t have access to the resource yet. Make sure all the commands from our configuration guide were executed successfully https://roomzio.atlassian.net/wiki/spaces/SUP/pages/280723586

If you’ve done the configuration correctly, check the actual permission on the resource with the following Powershell command

Code: ErrorAccessDenied ODATA disabled

If you have this error, most likely the resource isn’t part of the mail enabled security group yet, so the application doesn’t have access to it. Add the resource to the security group over PowerShell command or to solve the issue.
