This issue does occur if another software has modified your configuration in an invalid way. Please follow the following steps to fix this.
- Open the following path in your Windows Explorer: "C:\Windows\Microsoft.NET\Framework\v4.x.xxxx\Config". For the xxxx part, if there is more than one folder, use the one with the highest number.
- Open the file "machine.config" in the text editor:

- You should see the element marked in red, which is an empty DbProviderFactories element. Please continue only, if you have exactly this element, otherwise please contact us. You can damage your configuration if you make modifications on your own.
- In case you see the exact element above, please remove this line. Make sure to only remove this line and nothing else.
- Save the file and restart Outlook.
