Clearing Internet Explorer or Edge Browser Cache and Cookies to Refresh the Add-In


2 min read


The general recommendations after adjusting RGES customization, synchronization, or other settings are

  • refresh the Sidebar by right-clicking on it and then selecting Reload
  • close and reopen MS Outlook
  • log out and then log back in RG Email Sidebar

Normally, performing these actions is enough to refresh the Sidebar to apply the updated settings; however, in some cases clearing MS Edge and Internet Explorer cache and cookies may be additionally required. MS Internet Explorer 11 is used to render RGES Sidebar in MS Outlook on Windows systems, in both its Cloud (Web) and Desktop (.MSI) implementations. For this reason having MS Edge and Internet Explorer installed on your Windows system is a prerequisite for using the Add-In in your MS Outlook Desktop. Even if you do not use this browser, it is usually installed by default. Your MS Edge and Internet Explorer cache and cookies contain Sidebar rendering data; clearing the old data from them will refresh the Sidebar to reflect the changes in settings if other ways did not work out. In addition, cache and cookies clearing can help in certain rare cases of Sidebar interface elements being jumbled or displaying irrelevant data.
