Fix: Microsoft Teams Cannot Open Files in Desktop App

Fix: Microsoft Teams Cannot Open Files in Desktop App

Posted on April 8, 2021 by Madalina Dinita 4 Comments

Microsoft Teams is fully integrated with other Office applications, which means you can open your Word, Excel, and PowerPoint files directly in the desktop app. All you need to do is select the file you want to view and then click on the “Open in desktop app” option. Unfortunately, this option doesn’t always work as intended.

For example, the app keeps asking users to sign in. No matter how many times they enter their credentials, the “Sign-in required” alert won’t disappear. Or, when users click the file link, Teams says it’s “Opening” and then “All done. You can close this file now“.

Fix: Teams Desktop App Not Opening Files

Check Your URL Protocol Settings

When you open Office files in the desktop app, Teams uses the URL protocol to open the compatible Office app. So, check your URL protocol settings and tweak them if necessary.

  1. Navigate to Settings, select Apps & features, and then Default apps.
  2. Go to Choose default apps by protocol.choose default apps by protocol
  3. Scroll down and check if the right Office app is selected as the default app for your files.

    Thanks. Deleting the folder in %appdata% worked for me. Close app first, delete, start app again. You have to login again.

    Are you logging in with a different Microsoft account? Be sure you’re using the same email address that you used to purchase the MS365 Suite.

    I have the same issue as LL. I don’t have PowerPoint set as a default app, and the same thing, when I go to select it, it goes to Microsoft Store and wants to charge me. I have the whole MS365 suite.

    Excel is not listed as the default app for MS-EXCEL. When I got to select it, it wants to charge me, but I already have Excel. Any recommendations?
