Just upgraded to windows 10 and now my MS outlook 2013 calendar and contacts are not working. They do show up in the separate apps for calendar and contacts on the home page apps. How can I get them back to outlook?

Hello,

You can try these steps to fix the issue:

•  Click on Search bar >> Type cmd >> Right Click on Command Prompt >> Click on Run as administrator from the drag down list.
  
• Type sfc<space>/scannow and hit on enter button. This process will take some time.
  

•   Now, Restart your Computer.
