Hello,

I was wondering if there was any way to disable the addin manager feature in
outlook.
Tools > options > Other > Advanced Options > Add-In Manager

Basically looking to disable users from removing or adding plugins...I have
looked through the registry for both the HKLM and HKCU and could not find
anything that really jumped out at me. Not sure if i missed it or if there
needs to be a subkey added (or if it isn't even possible).

Thank you,

Chris

If an add-in is installed in HKLM, Outlook 2000-2003 won't even show that
add-in. Outlook 2007 will, but the user will not be able to modify an HKLM
registry key anyway.

Not sure exactly what you mean....
So I should delete the HKLM key and that will not allow them to disable it
or what?

No. Unless the user is a local admin or a power admin, the user (and hence
Outlook running in that user's context) will not be able to change the
LoadBehavior key of an addin registered in HKLM.

I think I am catching on, which key though
HKLM\software\microsoft\office\outlook\addins?
What keys need to be added?
I tried testing this with addins that were already in that key but i was
able to change them with a regular user account.
Unchecked the boxes in the addin manager then restarted outlook and the
addins did not load.

Thank you for the help

HKLM\software\microsoft\office\outlook\addins\<YourAddinName>,
"LoadBehavior" value.
What do you mean by "regular user account"? Is the current Windows user a
member of the local admins group? Or a power user?

This user was just a member of Domain Users.
No other privleges. Just to make sure I tried to open up regedit and other
MMCs and could not.

What do you see in that key's permissions (open it in regedit, right click,
Permissions)?
