Hi, at the moment I use Outlook [office 2010] as my main email program at work.  I was wondering if I can use that .PST file via Office for Mac 2011 which is what I want to use at home.

I use drop box and therefore I can sync the .pst file across both computers that way.

is this possible? or do I need to buy Office 365 and then install that on both computers and have my datafile stored in the Microsoft's cloud service?
