2.    Select the Info tab and click Manage COM Add-ins next to the Slow and Disabled COM Add-ins section.


3.    On the Slow and Disabled Add-ins window, you may see "SmokeballOutlookAddIn" listed.

  • If the message states "This add-in caused Outlook to crash. As a result, it was disabled.", click on Options, select Enable this add-in and then click Apply.

  • If the message states "This add-in caused Outlook to start slowly. It wasn't disabled because it's on the Always Enable list"., click on Options, select Do not monitor this add-in for the next 30 days and then click Apply.


4.    Select Close. The Smokeball add-in should reload momentarily.

SmokeballOutlookAddIn cannot be loaded due to a runtime error

If you are experiencing the following error message when ticking the SmokeballOutlookAddIn: 


"Load Behavior: Not loaded. A runtime error occurred during the loading of the COM Add-in"


this may be caused by an error with the installation of the add-in.


The next course of action is to uninstall and reinstall triConvey on your PC. Refer to our Desktop Troubleshooting guide on how to uninstall triConvey cleanly before reinstalling it.

Other COM Add-ins that may cause issues
