Error with Microsoft Outlook – doesn’t open at all any more

Hi there,

Next morning after 'force quit' of my Apple laptop iBook pro mid 2012; my Outlook  did not work. 

I've tried everything. On my Outlook I have many important messages - in Inbox and Sent folders.

My question is: 

If I uninstall my 'Office: mac 2011' and reinstall it again: Will I loose all my valuable information (inbox and sent folders)?
Or will they be saved somewhere on my laptop and automatically uploaded upon new installation?

I do not want nasty surprises and errasure of my three years of communication!

Please, let me know would unistall and reinstal sort out my problem with no loss of data?

Best, Jay_62
