No, Exchange Client Extensions are totally different from COM add-ins - they
use a different API and can only be installed in HKLM.

I did try it again. The Addins in the
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Outlo ok\Addins
come up if you select Tools-Trust Center-Addins
and then select Exchange Client Extensions on the Manage section
and then press Go. It appears to me that any extension that resides in the
machine registry is called Exchange Client Extension while extensiosn on
the
HKEY_CURRENT_USER are called COM Add-ins.

One can then enable/disable the Addins from that interface.

I'm just getting used with Outlook 2007 and some stuff is not exactly
clear.

Thanx for all the tips....

For Office 2007 - I believe that all addins do show up in the Trust
Center (Tools | Trust Center | Add-ins).

The reason I say so is because - I have a custom addin developed using
C#, VSTO , VS 2005 and in our current environement (Office 2003) it is
registered under HKLM so that users cannot disabe it.

I recently ported the addin over to Office 2007 (making few
modifications for compatibility and it registers under HKLM - but
still shows up in trust center.

Please correct me if I am wrong - Office 2007 addins always show up in
Trust Center irrespective if they are registered in HKCU or HKLM

Thanks
