I am converting from Office:Windows 2010. Do my current .pst files work on Outlook:Mac 2011? If not, how do I convert from Office:Windows to Office:Mac?
Yes! If you have a .PST file from Outlook for Windows (created using Outlook 2003 or later), you can import it into Outlook:Mac. Just transfer the .PST file from your Windows computer to your Mac (such as putting it on a thumb drive), and then go to File -> Import in Outlook:Mac.
For full instructions for how to import your .PST file into Outlook:Mac, read this help file: Import a .pst file from Outlook for Windows.
