I'm assuming here that you're (1) Going to have to continue classes after your August 10th start date and that (2) You're unable to do you classes and work at the same time (i.e. your school and company aren't in the same city and/or you can't do either one part-time).

To start, you should talk to your future employer and be clear that you're going to need more time to finish your bachelor's degree. Together, you can probably work out a solution. Perhaps it is pushing back your start date. Or perhaps it's some other option that lets you both work for Microsoft and finish your degree.

You should definitely tell them. It's implicit in your offer that you're going to get your bachelor's, so you don't want to anger an employer a few months down the line when they inevitably realize you didn't earn your degree. I've known folks in far worse predicaments who have both (1) told their employer about their problems and (2) still had a job.

Thank you for the response! Would you recommend talking with HR or should I go straight to my Manager/Hiring Manager?

I'd recommend going to your manager/hiring manager. Go to HR/recruiting if they tell you to or if they can't help you. Starting with your manager is preferable because (1) your manager is likely your advocate and (2) HR probably doesn't know you that well, especially given how large Microsoft is. Your manager wants to bring you onboard, so be sure to think of some strategies for working + attending school before you chat!
