What is the difference between "Is it ok for you?" and "Is it ok with you?"

Thanks,

Ryo
They could be synonymous or not. One or both could be used...or neither. It depends on the context. What's 'it'?
Hi Mister Micawber,

Thank you for your reply.

A: What time will you be coming?

B: Around 9 pm. 1) Are you ok with it? 2) Is it ok for you? 3) Is it ok with you?

In this context, which one would you say?

These all seem fine and natural, Ryo:

A: What time will you be coming?

B: Around 9 pm. 1) Are you OK with that? 2) Is that OK for you? 3) Is that OK with you?

#1 and #2 do seem to suggest that A has mentioned further contingencies surrounding the arrival time, where #3 does not necessarily do so.
