More than just 3 months back
Having three months back only is really odd. It makes this nice app a nuisance.

Currently iOS outlook only goes back 3 months into past events. It's sometimes very helpful to refer back to old calendar events but anything past 90 days isn't visible.. My request would be to allow calendar events to sync "all events" dating back to the first event ever created on the account.. I use outlook for work and use exchange.
In one sentence, please allow old events beyond 90 days, go infinitely back, modern iOS devices can handle it.

If you want us to use only Outlook's iOS calendar app while mobile, you must allow users to sync farther into the past than 3 months. Users must have the option to sync all events to our desktop Outlook and/or live.com calendars.

Incomplete! Events older than 3 months do not show up and there is no option in settings to enable.
