Certifications refresh: AI-focused and fundamentals updates

Thanks for the answer but if I don't have time to give the exam for the MS-900 certification, what happens after that?

So I can't give it after 3/31/2026? 

No, you cannot take the MS-900 exam after 31st March.

Is the MB-900 certification available and does it fully replace the MS-900?

Yes, as I said, the AB-900 exam is live and as I also said it only covers around 20-25% of the MS-900 exam

Which is better and more useful of the 2?

They have a different focus. AB-900 is more useful to Microsoft and the direction Microsoft is moving. MS-900 is more relevant to most people now managing their Microsoft 365 tenant and devices.

Also, is it a lifetime certificate and can someone add it to their bio like on LinkedIn?

Yes, Fundamentals certifications do not expire and can be shared on LinkedIn

Hi

1. all actual certifications are found in the clickable cert poster at https://aka.ms/certposter (it’s not obvious, and many miss that’s it’s conveniently clickable :))
2. You can read more about retirement here -

3. and some news here -

4. All Fundamentals does not retire - they are life long. But as seen in above article, AI-900 as example gets a refresh - as AI-901
5. MS-900 replacement is AB-900. A bit strange as not really same focus, and very strange Microsoft now has zero Fundamentals covering Intune, device / apps management - but that’s what it is

best of luck
