I need to share this because I was seriously about to give up. Failed the MS 203 twice in four months — first time with a 672, second time with a 694 (passing is 700). I'm an Exchange admin with about six years of experience and honestly thought I'd breeze through it. Wrong. Microsoft's hybrid configuration questions are brutal, and the mail flow troubleshooting scenarios are nothing like what you deal with day-to-day.
What finally clicked was switching up my study approach. I stopped just reading docs and started doing an MS 203 practice test every single day for three weeks. Timed, no skipping, reviewing every wrong answer. I also found a solid MS 203 study guide that broke down the recipient management and compliance sections in a way that actually made sense — those two domains were killing me.
Passed yesterday with a 762. If you're stuck in the 670–690 range like I was, I'd love to hear what exam tips worked for others. Specifically curious how people approached the hybrid topology simulation questions.
