Before you begin

Clearing your web browser's cache, cookies, and history may remove data such as the following:

  • Saved passwords
  • Address bar predictions
  • Shopping cart contents, etc.

While you should clear your web browser's cache, cookies, and history periodically in order to prevent or resolve performance problems, you may wish to record some of your saved information first. If you are unable to do so, see Troubleshooting alternatives below.

For details about browser cache, cookies, and history, see:

Computer
  • For desktop browsers, to quickly open menus used to clear your cache, cookies, and history, ensure that the browser is open and selected, and press Ctrl-Shift-Delete (Windows) or Command-Shift-Delete (Mac). If this doesn't work, follow the appropriate instructions below.
  • If the instructions below don't exactly match what you see, you may need to update your web browser to the latest version.

    If you don't see instructions below for your specific version or browser, search your browser's Help menu for 'clear cache'. If you're unsure what browser version you're using, from the Help menu or your browser's menu, select About [browser name]. In Firefox, if you don't see the menu bar, press Alt.

  • UITS strongly recommends that you use a supported browser, and not Internet Explorer (IE). IE 11, the last major version, no longer supports Microsoft Teams, and will stop supporting Microsoft 365 apps in August 2021.
