Internet explorer has blocked this site from using an ActiveX control in an unsafe manner.

This issue has been a documented by Microsoft in KB976539.  The problem may arise if the CRM for Outlook was installed but not configured, or the user attempts to access an organization that CRM for Outlook was not configured for.

In our scenario, CRM for Outlook was properly configured to our default organization, yet all users continued to receive this ActiveX warning.  Second, many of our clients use the CRM for Outlook within a multi-tenant environment.  We needed a clearer solution.

Below is a workaround that we’ve found to ‘correct’ this problem:

1. Open Internet Explorer
2. From the Tools menu, select Internet Options
3. Switch to the Security tab
4. Click the site zone where you’ve placed the URL to your CRM (we place the CRM URL in the local intranet zone), and click Custom Level
5. Under the ActiveX controls and plug-ins, enable this option:

Initialize and script ActiveX controls not marked as safe for scripting

Save the new settings, and restart Internet Explorer.

The above recommendation was documented in MSDN’s article: Improve the Outlook Experience with CRM, part four
