I have the same issue. I went to MS Downloads, found Office 2013 Service Pack 1 32-bit Version, and downloaded it. When I tried to run it, it said there wasn't enough memory.
ok i will do a step by step.
swipe from the right side of the screen
select setting
then Change pc settings
select update and recovery
if you have to update to get the newest updates
then select view details
u will then see an option to select the office update, this is what fixes the outlook issue
