If Outlook says working offline, it means that it's not connected to the internet and can't send or receive emails. To fix this issue, you can follow a few simple steps. First, check your internet connection and make sure it's working properly. Then, disable the "Work Offline" option in Outlook by going to the "Send/Receive" tab on the ribbon and clicking on "Work Offline" to turn it off. If that doesn't work, try disabling the "Use Cached Exchange Mode" option in Outlook's account settings. You can also try creating a new Outlook profile or repairing your existing one. Finally, make sure you have the latest version of Outlook installed and update it if necessary. By following these steps, you can easily fix Outlook when it says "Working Offline."
