I did not know there was a registry key that did the same as removing it
from the list in Help About ... What is the registry key ?

Unhandled exceptions is the #1 cause.

Disabled addins can usually be re-enabled only by deleting the registry
key for disabling addins or by removing the addin from the disabled items
list in the Help, About, Disabled Items dialog.

Another cause of disabling can be script stoppers. If you use "New" or
"CreateObject" in your code or access Windows Scripting your addin might
be disabled because the script stopper causes that to fail, the exception
is unhandled and the addin gets disabled. Also very common.

One of my company's customers is experiencing a strange problem with an
Outlook add-in we built. The add-in is often disabled when some of the
users start Outlook, and they have to go into COM add-ins to add it
back. The problem is that this happens pretty regularly. They'd add the
add-in, it'd work for a while, but some days later, when they start
Outlook again, the add-in disappears again, and they have to add it
back again.

Some (but not all) of these users have
HKCU\Software\Microsoft\Office\Outlook\Addins\OurO utlookAddin.OutlookAddin
set to 0 or 1. But changing it to a 3 hasn't worked.

Are there any known causes that leads to an Outlook addin being
constantly disabled?

TIA
