I would ask your exchange administrator. I can't imagine a valid business case for limiting downloads to 2kb in this day and age of unlimited data plans (unless you're all on some ancient measured data plan?). I'd say it's got to be a setting on their end, though I'll admit I've never heard of that one. If it is, it would be better to solve it "for rea"l than try to hack things on your phone, bypassing server policies (risking your job in the process) and letting your IT people think they did a great job with the migration when they were really phoning it in.
