Microsoft added a new feature in Outlook 2013 to help you manage add-ins that cause
performance or crashing problems. When an add-in takes too long to boot, Outlook will disable the add-in automatically. When this happens, Outlook provides a warning in the notification bar as shown below and you can take appropriate action.
When you see the add-in problem alert, click the 'View Disabled Add-ins' button on the
notification bar to display the Disabled Add-ins dialog.
The Disabled Add-ins Dialog
The Disabled Add-ins dialog lets you control add-ins that have caused a problem for Outlook.
When you display this dialog, you’ll notice that Outlook tells you how much time the add-in
In the example below, the ChilliDB Outlook Plug-in caused Outlook to start slowly and added over 3.9 seconds to Outlook start up time.
To ensure the ChilliDB Outlook Plug-in is always enabled, click the button 'Always enable this add-in', Outlook will then always allow the add-in to run no matter how much time it requires during Outlook start up.
