Cause:

Most probably, this is an incompatibility issue of Controlio's monitoring components with your MS Outlook version or settings.

Solution:

We will need to disable Microsoft Outlook application monitoring from the “Emails” section of the monitoring profile. 

• Navigate to the “System” - “Monitoring Profiles” tab located on the left-handed side of your screen.
• Click on the name of the monitoring profile that is being used for monitoring the needed user.
• Find the “Emails” tab, and make sure that “Microsoft Outlook application monitoring” is not ticked.
• You may also disable the monitoring of “Emails” entirely by removing the tick next to “Emails.”
  
  Note: If this solution is not suitable for you, or if these steps were not helpful, please consider Submitting MS Outlook debug log. This will help us get a clear idea of what is causing this issue.
