The MS-203 exam is the official Microsoft exam behind Microsoft 365 Messaging — passing it earns you the Microsoft 365 Certified: Messaging Administrator Associate certification, a credential positioned at the Associate level. It is built for candidates who want to validate the skills measured by Microsoft 365 Messaging. Depending on your track, the exam is also linked to the Microsoft 365 Certified: Messaging Administrator Associate certification, so one pass can move you toward more than one Microsoft credential.
The MS-203 exam presents 40-60 questions to be completed within 120-150. That pace leaves little room for second-guessing: read each question carefully on the first pass, flag the ones you want to revisit, and keep moving instead of stalling on a single item. Before exam day, run at least one full timed session in the TestSimulate desktop or online test engine with a comparable question load — a steady rhythm under the clock is a trainable skill, and it is often what separates a pass from a near miss.
To pass the MS-203 exam you need 700 (out of 1000), and the official registration fee is $165 USD (may vary by region). Keep in mind that a failed attempt means paying that fee again in full — retakes are not discounted. Given the cost, self-test before you book: if you can score comfortably above the passing mark on two or three consecutive timed TestSimulate practice tests, your budget is far better spent on the exam itself than on a retake.
MS-203 has been retired (June 2023). It was part of the Microsoft 365 Certified: Messaging Administrator Associate certification track. Candidates are typically expected to have experience with Exchange Online and Microsoft 365 administration. Because Microsoft revises its certification programs from time to time, treat this as a starting point rather than the final word. Confirm the current eligibility requirements on the official Microsoft exam page before you register.

Please wait while the virtual machine loads. Once loaded, you may proceed to the lab section. This may take a few minutes, and the wait time will not be deducted from your overall test time.
When the Next button is available, click it to access the lab section. In this section, you will perform a set of tasks in a live environment. While most functionality will be available to you as it would be in a live environment, some functionality (e.g., copy and paste, ability to navigate to external websites) will not be possible by design.
Scoring is based on the outcome of performing the tasks stated in the lab. In other words, it doesn't matter how you accomplish the task, if you successfully perform it, you will earn credit for that task.
Labs are not timed separately, and this exam may have more than one lab that you must complete. You can use as much time as you would like to complete each lab. But, you should manage your time appropriately to ensure that you are able to complete the lab(s) and all other sections of the exam in the time provided.
Please note that once you submit your work by clicking the Next button within a lab, you will NOT be able to return to the lab.
