What causes Outlook add-ins to not load on startup

David Phillips 

Update Workplace Desktop

Enable your outlook add-in.

Verify the Add-In is Enabled.

Check Slow and Disabled COM Add-Ins

1. Open Outlook.
2. Go to File > Info to display the Account Information window.
3. In the Slow and Disabled COM Add-Ins area, click the Manage COM Add-Ins button. This will open a detail popup.

Edit the Registry

1. Click the Windows Start menu.

2. In type regedit in the search box and press the Enter key. The Registry Editor window will open. Navigate to 
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Outlook\Addins\AutotaskOutlookPlugin.AddIn
   
    
3. This registry key has an entry named LoadBehavior. If the Data column value for LoadBehavior value is set to 0, the Outlook plugin will not load automatically. To ensure that the plugin loads automatically, you must set the value to 3. To do so, double click LoadBehavior, enter 3 in the Value data field of the resulting popup, and click the OK button.
4. Restart Outlook. The issue should be resolved.
