Will MSFT rescind my FTE offer if I couldn't sign Interim Offer Letter?

I had a query when I saw my interim offer letter of Microsoft. So I mailed them first without signing it but the deadline of signing it passed away while awaiting for their response. Am I out of process because of this? Cuz I mailed them regarding this and haven't heard back yet. What should I do, I'm afraid. I've Amazon onboarding early in June but I wish to join MSFT(date choosen late July). I'm afraid if I deny Amazon now and after a month if MS say I'm out of process, I'll be left nothing in my hands 😰😰. Yoe: new grad India #engineering #software #swe
