All / most of my users are getting a pop up that Callercheck exploit was prevented in Outlook

We are using Outlook 2016 (365) and getting widespread 'CallerCheck exploit prevented in Microsoft Outlook.'

How do I determine if this is outlook or a 3rd party plugin.  We all have one plugin in particular, from Newforma.

Please advise!

Thanks,

Phil

  • Hi Phil Lewis,

    To check the plugin detail that could be causing the exploit alert can be found in the event viewer.

    Open the Event viewer > Win+R > Type "eventvwr" and filter for HitmanPro.Alert Event ID 911. You might see something in the below picture.
