Does anyone know how to remove/disable an Addin in Outlook 2007?
In 2003, that was easy through the advanced featers menu, however,
in Outlook 2007, I can't find any place in the interface to just
disable an Addin. Any clues on how to do this?

Thanx in advance.
 
I did try that. However, not all addins are listed. For example, Outlook Spy
is not listed and I have it installed. Is there a registry of file that I can
go and edit and
remove the loading of addins?

Did you select the appropriate entry in the "Manage" combo box and click Go?
Also note that COM add-ins installed in HKLM (as opposed to HKCU) will not
be listed.

Dmitry,

That works ok for listed applications. However, I have an Addin Installed
that has a memory leak when I delete contacts from folders. After about 40
Deletes, Outlook Hangs. This application is not listed in the Trust center in
Outlook.
Most likely is was installed in HKLM . How can I prevent Outlook from loading
this addin?

You can remove/rename the add-in's key in
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Outlook\Addins

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
 
I did try it again. The Addins in the
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Outlook\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....

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

So then does anybody know how we can hide the addins from the Trust
Center. I have an addin which is absolutely mandatery to be running at
all times. In Office 2003 - we hid it from there (so users dont
disable it) by HKLM.

How do we do this in Office 2007 (not allowing users to disable it)

Thanks
 
Try to set the access rights on the your addin's registry key in
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Outlook\Addins
so that only admins can delete/modify entires there.
Also note that unless the current user is an admin/power user, it will not
be possible to modify *any* registry key in HKLM, so your add-in will stay
enabled.

Thanks for the response.

I am a local admin on my machine and hence always had acces to enable/
disable them. Never realized that non-admins will not have access to
it. Will try it on a regualr workstation where I dont have access
rights.

Also - just out of curiosity - how do we set the access rights in the
path you mentioned in the addins registry key. I dont see any specific
key which would deal with this.

Thanks
