From time to time all Microsoft web applications (like CloudExtend) may end up sending too many requests to their destinations. For users on Microsoft Windows this typically happens when something called the Desktop Web App Viewer is consuming too many resources or you are not running the most recent version of the Web App Viewer.

How To Fix It

If this is a constant issue for you and ending the process as described below only works temporarily then it's likely that you need to update the viewer of the browser that renders the application. Try the steps below first and if the issue reoccurs see this section to learn how to install the new viewer.

🤷🏽 --> If the steps below are not clear for you the closing Outlook and rebooting your computer will also work.

  1. Close Outlook

  2. Open “Task Manager “(Ctrl-Shift-Esc), find ”Desktop App Web Viewer“ or "Microsoft Edge WebView2" processes and kill them:
    right-click → ”End task” (Temporary workaround when freezing happens)

  3. Open Outlook again
