SOLVED: Office365 Sorry, We Couldn’t Open Word Excel PowerPoint

After working on a file for a few months I found this message:

Office365 Sorry, We Couldn’t Open FILE NAME Word Excel PowerPoint

The error did not appear when trying to open the file using the Word WebApp, but did appear when trying to open the file using the full Word desktop app.

Fortunately, there is a very easy fix.

How To Delete Office 365 Cached Files

  1. Close all MS Office files and programs
  2. Launch FILE EXPLORER
  3. Expand C:\Users[USER NAME]\AppData\Local\Microsoft\Office\16.0\
  4. Delete (or just rename) the folder OfficeFileCache
