Sharepoint 2013 and Exchange 2010

is it possible to seamlesslyintegrate exchange 2010 tasks and personal calendars with sharePoint 2013 sites? Does this require OAuth configuration? Are there any exchange 2010 work-around for making this possible?

I appreciate any information that you provide

Thanks,
