MO-210 vs MO-200: what actually changed?
MO-200 (Microsoft Excel, Office 2019) is MO-210's predecessor, and it is not retired — Microsoft's own exam page lists no retirement date — but it has been pulled from Microsoft's certification browsing and search pages, so almost nobody encounters it as an option anymore. The real difference is two things at once: MO-210 adds dynamic-array and random-data functions Office 2019 did not have (SORT, UNIQUE, RANDBETWEEN, SEQUENCE), and the weighting shifted — worksheet and workbook management roughly doubled, from 10-15% to 25-30%, while formulas/functions and charts each dropped a notch.
Checked against Microsoft’s own published pages on September 16, 2026.
The numbers
MO-200 is not retired — it is just no longer surfaced
Checking Microsoft's own exam page for MO-200 directly: its retirement date field says "none," meaning it remains a technically schedulable exam. But the page itself is marked hidden and excluded from search indexing, meaning Microsoft has stopped surfacing it through its own certification browsing and search — it still exists, but almost nobody arrives there without a direct link, and Microsoft's active promotion is entirely behind MO-210.
For a practical purpose, treat MO-200 as legacy: any school, employer, or job posting asking for current Excel certification almost certainly means MO-210 (Microsoft 365 Apps), since that is the exam actually being issued and promoted today.
What content is actually new
MO-210's formula domain includes SORT() and UNIQUE() — dynamic-array functions that spill results across multiple cells automatically — plus RANDBETWEEN() and SEQUENCE() for generating numeric data. Office 2019, the platform MO-200 is built on, predates dynamic arrays as a feature entirely, so none of these four functions could have been tested on MO-200.
Microsoft 365 Apps also brought ongoing co-authoring and cloud-save improvements that Office 2019 (a static, boxed-product release) did not have in the same form, which is part of why the certification was re-based on the newer platform rather than simply revising MO-200 in place.
The weighting shifted, not just the feature list
This is the less-discussed difference. MO-200's own domain weights: Manage Worksheets and Workbooks 10-15%; Manage Data Cells and Ranges 20-25%; Manage Tables and Table Data 15-20%; Formulas and Functions 20-25%; Manage Charts 20-25%. MO-210's weights: Worksheets and Workbooks 25-30%; Data Cells and Ranges 25-30%; Tables and Table Data 10-15%; Formulas and Functions 15-20%; Charts 15-20%.
Put plainly: worksheet and workbook management roughly doubled in importance, tables dropped by a third, and formulas and charts each eased down a notch. Someone who studied for MO-200 and assumes the same balance applies to MO-210 will under-prepare the domain that now carries the most marks.
What costs people points
It is hidden from Microsoft's own catalog, not retired — its exam page carries no retirement date. The practical difference for almost everyone is the same either way (MO-210 is what's actually being asked for and promoted), but the two are not the same fact.
Worksheets and Workbooks nearly doubled in weight between the two exams. Studying MO-210 with MO-200's balance in mind under-prepares the domain that now matters most.
Older study material may not cover SORT(), UNIQUE(), RANDBETWEEN(), or SEQUENCE() at all, since none of them existed on the Office 2019 platform MO-200 is built on. Confirm any study resource is built for Microsoft 365 Apps before relying on it.
Related questions
Can I still take MO-200 instead of MO-210?
Technically, its exam page lists no retirement date, so it remains schedulable. In practice it has been removed from Microsoft's own certification browsing and search, and virtually every current requirement — schools, employers, job postings — means MO-210.
What functions does MO-210 have that MO-200 does not?
SORT(), UNIQUE(), RANDBETWEEN(), and SEQUENCE() — all part of MO-210's Formulas and Functions domain, and all dependent on dynamic arrays, a feature that did not exist on the Office 2019 platform MO-200 is built on.
Did the domain weighting change between the two exams?
Yes, substantially. Worksheets and Workbooks went from 10-15% on MO-200 to 25-30% on MO-210 — the single biggest shift — while Tables and Table Data, Formulas and Functions, and Charts each dropped a notch.
If I already passed MO-200, do I need MO-210 too?
That depends entirely on who is asking. If a current requirement specifies MO-210 or "Microsoft 365 Apps," an MO-200 pass on the older platform may not satisfy it — confirm with whoever set the requirement rather than assuming the two are interchangeable.
