We're currently trying to migrate from Exchange 2010 (SP2) to Office 365. Everything is set-up and Single-Sign-On is working great (with AD FS). Because we are a large organization we decided to use the &quot;hybrid&quot; deployment. <br />
<br />
After completing the steps Microsoft provides we get an error message saying &quot;The signup domain 'nl' derived from 'ouderdomain.nl' is not a valid domain<br />
