If you receive the "Cannot display the folder.  Microsoft Outlook cannot access the specified folder location" error, you typically need to rename or delete your .ost file.  

Delete the Outlook .ost file

  1. Close Outlook and Skype for Business.
  2. From the Start menu, choose Run.
  3. In the Run window, type this path (or use copy/paste) in the Open box  "%LOCALAPPDATA%\Microsoft\Outlook\"
  4. Click OK
  5. Find the .ost file associated with your email address and delete it (you may need to Show Hidden Files and Show Extensions to see the file)
  6. Restart the computer
  7. Restart Outlook

A new .ost file will get created when you restart Outlook.
