"In fact im not sure ive ever seen a 64bit build of Outlook...I could be wrong there though."
I have run 64 bit Outlook 2013 on windows for ages (holding off on 2016 upgrade until it's had a few more patches)
The Office suite has been available in 64 bit for ages (typically a few less bells and whistles but can cope with various large files that makes 32 bit Office apps die, plus DEP)
Businesses like 64 bit office as Hardware Data Execution Prevention is always on so a bit more secure for your average luser than 32 bit.
