Office 365 not responding due to a long-running script

What to do if Office 365 becomes unresponsive

1. Update your PC to the latest Windows 10 version

1. Select Start
2. Click on Settings (the gear-shaped icon in the Start Menu)
3. Click Updates & Security
4. Select the Windows Update tab in the sidebar
5. Select Check for Updates
   • If an update has already been downloaded, select Update now
6. Restart your PC

Additionally, you can also update your Windows 10 PC using a third-party Windows Update Manager.

2. Update your Internet browser

According to official Office support, Edge, Internet Explorer 11, Firefox and Chrome offer the best experience for Office 365 web services on Windows 10:

While some of these browsers automatically update when you open them, some need to be manually started. Check out each respective browser‘s documentation to see how to properly update them.

3. Clear your Internet browser’s cache and cookies

Office 365 may have problems running when the browser‘s cache is already full of data. As such, it is a good idea to perform a cache cleanup once in a while and see if that solves the issue.

Check out these links for official guides on how to clear your cache and browsing history on all of the supported browsers:

• Microsoft Edge
• Internet Explorer
• Mozilla Firefox
• Google Chrome

If you tried all of the solutions above and the issue still persists, you should consider contacting Office 365 support.
