Cleared MS-203 last week with an 892 out of 1000. It took me about 6 weeks of prep, averaging 1.5 hours on weekdays and 3 hours on Saturdays. I'm an Exchange admin with 4 years of experience so the on-premises concepts weren't a problem, but the cloud-specific compliance and security topics needed dedicated time.
Here's roughly how I split my hours: Exchange Online configuration and recipient management got about 30% of my time, mail flow and transport rules got 25%, message hygiene and security including Defender and Safe Links got 25%, and compliance features like retention policies and eDiscovery got the remaining 20%. The compliance section was the most unpredictable on the actual exam — in hindsight I'd push that to 30% and trim recipient management time.
For resources I used Microsoft Learn paths, a Udemy course, and MeasureUp practice tests. The MeasureUp questions are harder than the real exam but they expose knowledge gaps faster than anything else. I'd recommend doing a diagnostic pass on MeasureUp first, identifying your weakest two areas, and hammering those before touching anything else.
The transport rules section on my exam had a lot of "which condition or action achieves this result" scenario questions. If you're weak on mail flow I'd strongly recommend building rules in a test tenant rather than just reading about them.
Good call on MeasureUp. I used it for MS-700 too and the same pattern holds — harder than real questions but the explanations for wrong answers are where the real learning happens. Worth every dollar.
892 is a strong score. I passed at 812 a few months ago and the compliance section was also where I felt least confident. The eDiscovery workflow questions specifically — the order of operations matters more than most people prepare for.
Honestly I almost quit at week three. I'm an Exchange guy too, so the on-prem stuff felt like home, but the compliance and security side kept making me feel like I knew nothing. Retention policies, DLP, sensitive info types, the whole eDiscovery flow. I bombed two practice runs in a row and sat there convinced I'd booked the exam too early. What kept me going was just refusing to lose the booking fee, no joke. So I stopped trying to memorize and actually went into a trial tenant and clicked through every policy myself until it stuck.
That changed everything. The cloud topics are weighted heavy, way more than the mail flow stuff I was comfortable with, so don't do what I almost did and overstudy the easy parts. If you're sitting there feeling dumb, that's normal, push through it. I went in expecting maybe a 700 and walked out with way more than that. You're probably closer than you think.
Honestly I almost rage-quit around week three. The compliance stuff -- retention policies, eDiscovery, information barriers -- felt endless and I kept bombing the practice sections. What finally clicked for me was drilling fundamentals first, like going back to free microsoft 365 basic stuff just to make sure my foundation wasn't shaky. Embarrassing but it helped.
Once I stopped trying to memorize every setting and started understanding the "why" behind each policy type, it got easier. You don't need to know everything perfectly -- you need to know enough to reason through the questions. Passed with an 887 so not as high as yours but I'll take it. Don't give up when it feels impossible, that wall is usually right before it starts making sense.
I failed my first attempt at 692 and honestly it wasn't even close. I'd spent most of my prep time on the Exchange hybrid stuff since I figured that was my strong suit, but the exam hit compliance and information governance way harder than I expected. Second time around I completely flipped my focus — less time on what I already knew and way more on retention policies, eDiscovery, and the Defender for Office 365 configuration specifics. That shift made all the difference.
One thing that helped early on was going through free microsoft 365 basic practice questions just to get comfortable with how Microsoft phrases things before diving into the harder material. It sounds simple but that framing really matters when you're reading exam questions under pressure. Congrats on the 892, that's a solid score — if anyone's prepping now, don't make the mistake I did and skip the compliance modules because they feel boring. They're not optional.
