I've checked a few more things and have got it to work under all-users / local machine.
It works if I register with regasm and then manually put the registry entries under
HKEY_LOCAL_MACHINE\Software\Microsoft\Office\Outlook\AddIns on the virtual machine
Or
HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\Office\Outlook\AddIns\ on my development machine with 64bit windows + 32 bit office
I've also checked using the same settings but for an excel add-in, which works fine.
Any Ideas?
