Add-ins can become disabled if Outlook crashes frequently. One way to detect
if an expected add-in doesn't get loaded is through the COMAddIns collection:

If Application.COMAddIns(1).Connect Then
MsgBox "The add-in is connected."
Else
MsgBox "The add-in is not connected."
End If

You can run this during the Application_Startup event.

This is most likely because the add-in is listed in the Disabled Items
list
from the Help - About menu.

It was indeed this! Thanks a lot!
Any idea why this happens? and is there somehow a way to get a warning when
an Add In gets disabled?
