We have restored an old ms CRM database over a newer version. But when I try and add users which were already existed in newer version I get an error.
If I delete the users from our of active directory and then try to add them to CRM it works fine.
Is it possible that CRM is storing user information in the MSCRM_CONFIG. And can this be removed in a supported way?
Have a look at the SystemUser in the MSCRM_CONFIG table, I think i need to remove the users from this table. but I can't do a delete statement as it's not supported. :)
