What to do, if I can’t install the Outlook integration?

You may need help from your internal IT administrator to make it work.

It may be due to:

• You running an older version of the integration, where the certificate is no longer valid. Un-install and re-install the integration to make sure you use the latest version
• Your computer is set up with different settings than the default the certificate trusts. You can read more and get help from Microsoft. If you are not IT administrator yourself, we recommend that you ask your internal IT administrator for help to do the below setup

You can give this solution a try:

1. Open Registry editor on your computer by pressing the Windows key on your keyboard
2. Write regedit
3. Right click the Registry Editor
4. Select Run as administrator
5. Add this address in the line at the top: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\Security\TrustManager\PromptingLevel
6. Here you must change the value for MyComputer from Disabled to AuthenticodeRequired or Enabled depending on your security settings. The default for MyComputer is Enabled
7. Un-install and re-install the Outlook integration
