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.
