Known add-in conflicts

ClearContext follows Microsoft's recommended practices for Outlook add-in development to ensure that the product works with the widest range of third party Outlook add-ins. That said, we do find issues with certain add-ins from time to time. See the list below for reported issues and workarounds where available. These reports may reflect issues with a specific or older versions, and don't necessarily mean that everyone will experience a compatibility issue.

  • Avast - conflicts and/or performance issues may result when running Avast.
  • Apple Outlook Add-ins - iTunes and Outlook Change Notifier - both of these add-ins have been reported to cause Outlook issues, regardless of what other add-ins you have installed. If you aren't synchronizing an Apple device to your Outlook calendar, you should disable them.
  • WindowBlinds from Stardock - a couple of users have reported display problems in the Dashboard and the Notifications Summary when running this Windows skin.
  • Interwoven MailSite - we have not tested this problem in house, but one user has reported that the they could not use MailSite after ClearContext was installed. Please let us know if you experience this issue.
  • Aladdin Add-ins - it has been reported that the Aladdin Outlook Add-ins cause the main Contact tab in the Outlook ribbon to disappear. Disable Aladdin to resolve.
  • HP Ease Archiving Utility - it has been reported that running the HP Easy Archiving Utility and ClearContext at the same time causes the ClearContext toolbar and menu to disappear. Disable the HP add-in to resolve.
  • Taskline - When using the QuickTasks feature, Taskline and ClearContext can try to update the newly created task at the same time, potentially causing certain attributes such as the Project not to be saved.


If you suspect that you are experiencing a problem with an Outlook add-in that is not listed, try disabling all other add-ins and try re-enabling them one at a time to determine if a specific add-in is causing a conflict.

  1. Go to File > Options > Add-ins
  2. Select the type of add-in you would like to disable in the Manage drop down
  3. Click Go
  4. Uncheck the add-ins you want to disable
  5. Click OK, you may need to restart Outlook. This is an especially useful technique when trying to identify the source of performance issues. If you find a direct conflict with another add-in, please contact us and let us know about the issue so that we can investigate further.
