Dear @Retha Janse van Rensburg,
Thank you for posting your question in the Microsoft Q&A forum!
Firstly, may I kindly ask if you switch back to "Classic" Outlook by turning New Outlook Off. If for some reason you don’t see a toggle in the new Outlook for Windows, Kindly check Toggling out of the new Outlook for Windows preview - Microsoft Support
In this case, please kindly follow these methods below and check if it helps:
Method 1:
- In Outlook > click on the File > Select Options > Click on General in the left-hand menu.
- Scroll down to the Start-up options section and uncheck the box next to Opt in to the New Outlook. (This toggle Switch is actually at the very bottom of the General Tab under the title 'New Outlook Options)
- Click OK to save the changes.
Method 2: If you continue to experience issues, you can also try editing the Windows Registry:
- Press Win + R to open the Run dialog box, type "regedit", and press Enter.
- Navigate to
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Outlook\Preferences - Find the entry named UseNewOutlook and set its value to 0.
- Additionally, navigate to
HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Options\Generaland set the HideNewOutlookToggle value to 1.
Method 3: Uninstall New Outlook:
Right-click the Outlook (new) item on the Start menu and use the Uninstall option there. See also Uninstall or remove apps and programs in Windows
