A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Sorry to hear that you’re having trouble accessing Add-ins in Word and Excel. Since you mentioned that everything was working normally until about three days ago, could you please provide a little more information ?
Could you share a screenshot of the exact message you receive when it says that the list cannot be retrieved? Is the Add-ins/Get Add-ins button greyed out in both Word and Excel, or does this happen only sometimes?
Are you unable to access all add-ins, or is there a particular add-in you are trying to use? Did anything change on the computer shortly before the problem started, such as an Office or Windows update, account/sign-in change, antivirus or security software change, VPN/network change, or installation of new software?
