What is necessary to ensure user emails and usernames match Microsoft requirements?

Transforming the data as it is passed from Okta is crucial to ensure that user emails and usernames meet Microsoft requirements. This process involves modifying or formatting the data during the transfer from Okta to Microsoft services, ensuring that the usernames and email addresses conform to Microsoft’s specific criteria and character limitations.

Microsoft has specific guidelines regarding acceptable formats for usernames and emails, and the transformation process allows for compliance before the data reaches the Microsoft environment.

Changing them directly in Office 365 could lead to inconsistencies and might not address the root issue if the original data from Okta was not compliant. Default settings in Okta may not cater to the specific requirements laid out by Microsoft, as they may need to be adjusted to fit the necessary parameters. Federating the domain in advance does not guarantee that the existing data will adhere to Microsoft’s requirements; it primarily deals with establishing trust and access between domains. Therefore, transforming the data ensures compliance proactively during the synchronization process.
