Contact Microsoft Training and Certification Support
Because the standard Microsoft Community does not handle certification issues, you must contact specialized support to resolve exam profile and registration loops.
Certification and exam registration systems are handled by a dedicated department to ensure profile security and correct linkage with testing partners like Pearson VUE. The general support forums cannot view or modify your certification profile.
Navigate to the official Microsoft Training, Certification, and Program Support forum at https://trainingsupport.microsoft.com/en-us.
Click on the 'Microsoft Certification' category to access exam-related support topics.
Click on 'Ask a question' to create a new thread detailing your MS-900 registration loop issue. A forum moderator will reply and initiate a private message to safely collect your profile details and fix the backend loop.

Frequently Asked Questions
Why does my Microsoft Learn exam registration keep looping?
Registration loops generally occur due to conflicting browser cache, special characters in your certification profile address, or temporary backend synchronization issues between Microsoft Learn and the exam delivery provider.
Can general Microsoft Support help with exam registration?
No. General Microsoft Support focuses on Windows and standard Office software issues. Exam registration, certification profiles, and Microsoft Learn issues require assistance from the specialized Training, Certification, and Program Support team.
How can I fix the 'All set' screen loop immediately without contacting support?
You can try bypassing the loop by using a completely different web browser, utilizing an InPrivate/Incognito window, or ensuring your profile details (like address and phone number) contain only standard English characters with no symbols. If the issue persists, backend support is required.
