All of a sudden when I try open outlook I see this message:

Dyld Error Message:   Library not loaded: @rpath/mbukernel.framework/Versions/14/mbukernel   Referenced from: /Applications/Microsoft Outlook.app/Contents/MacOS/Microsoft Outlook   Reason: image not found
Original Title: "can't open outlook for mac" 
Hi - can you please help.  Outlook was working fine until today - when I click on the icon i get a message "Microsoft cannot be opened because of a problem" 
  The key error message seems to be: 

Dyld Error Message:
  Library not loaded: @rpath/mbukernel.framework/Versions/14/mbukernel
  Referenced from: /Users/USER/Documents/Microsoft Outlook.app/Contents/MacOS/Microsoft Outlook
  Reason: image not found

Am not  technically minded at all - grateful for any help in layman's terms - many thanks
