Hello @Tom Hansen, unfortunately those of us that have an organization that allows for multiple email domains, changing of domains, and employees moving across domains, it can cause a real mess in freshservice. If you have a business system, outside of Azure or Active Directory, that is your single source of truth for user data then it requires some heavy lifting to properly manage requester and department data. We have such a system and I had to build an application the sits between our Business System and Freshservice. It’s job is to take creation of employee records, changes to employee records, new location records , and updates to location records from the Business System, and create, update, or delete freshservice requester and department data using the Freshservice API.
