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.

  • 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.
  • Apple, iTunes and iCloud Outlook Add-ins - (including the Outlook Change Notifier) 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 Outlook, you should disable them.
  • Avast - conflicts and/or performance issues may result when running Avast.
  • 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.
  • 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.
  • RoboForm - In some cases when RoboForm is enabled with Outlook, severe slowdowns can occur. To resolve this conflict, go into the RoboForm settings and either disable integration with Windows applications or with Outlook specifically.
  • 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.
  • WindowBlinds from Stardock - a couple of users have reported display problems in the Dashboard when running this Windows skin.


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. In Outlook, 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.
