As of 2 days ago, Outlook for Mac suddenly would not open for me at all. I click on the icon and it starts to look like it is starting normally, then for a split second it shows the "Initializing..." screen, and then it quits altogether.  

I thought maybe it was because I was cleaning up my computer files the other day, so I decided to remove the app altogether and re-install Office for Mac 2011.  I re-installed it, and now it is doing the exact same thing.  The other Office for Mac apps still seem to work fine.

I am using a MacBook Pro 13-inch Early 2011 version with OS X Yosemite Version 10.10.1.  

I have an Office 365 account through my work exchange server, so I am at least still able to check my mail online in the meantime. 

Thank you for any help or resources you can offer.
