Currently supported sync windows: 1day, 3 days, 1 week, 2 weeks, 1 month (!), All messages. And as far as I remember this list is done in this a way not (only) because of User Interface designers but also because this is the list supported by Exchange. 90 days was requested and I am unsure this is supported by Exchange. I know, trust me. I have tried all the available competing solutions on the market. This is part of my job.
