Outlook 2007: Disabling/Enabling Add-ins
This describes how to re-enable/enable and disable add-ins in outlook. This is how to correct a program that installs an outlook plugin that you don’t use or want.
Disable/Enable Add-ins in Outlook 2007:
1. In Outlook 2007, go to Tools > Trust Center
2. Click on the Add-ins section
3. You will now see all active, non-active, and disabled add-ins. Click on the add-in you want to enable/disable and then click on the Go button towards the bottom.
4. This will then open up the COM add-ins page. You can then check/uncheck the add-ins you want to enabe or disable.

Excellent. Both the Plaxo plugin and the Google Sync software makes Outlook hang.

The Add-In “Outlook Connector Extensions (msncon32.dll) cannot be loaded and has been disabled by outlook. Please contact the Add-In manufacturer for an update. Please uninstall the Add-In.

When you click “Go” change the button before it to “COM Add-Ins” to “Exchange Client Add-Ins” or something like that. Look in there for it.

When I try to disable “Outlookaddin” in the tools>trust center>add-ins, the computer pop up says I have to be an administrator… but I am the only one who uses this computer and do not know how to show that I am the administrator so I can disable the add in.

Ok, wtf.. When I go into the Trust Center > Add-ins, I don’t see any check/uncheck box by the add-in (nor does the picture you posted above show any disable/enable boxes) and I don’t see any option there to disable them. And yes, I’m admin on my machine. What’s the trick here?
Roger said on March 5, 2010
Thanks ! Microsoft’s way of thinking is getting weirdier each year.
Roger said on March 5, 2010
Hello, CT:
You have to select the proper option in the “manage” dropdown below (I suggest you to check all the opts) and then click on the button; you’ll find there a list where you can uninstall as well as uncheck the plugin in trouble…

Microsoft did us no favors by using the “GO” button. As if that means anything to anyone. GO what, GO where? Stupid.
Should be right there > disable/enable/remove whatever.
Sometimes updates to products are done just for the sake of it. Or by people that don’t actually use them. Ask the Vista development team about how that worked out. Biggest failure ever. Moving buttons here and there, tweaking the UI according to “studies of effectiveness”. Yeah, effective for who? Most of us having been using Windows for 20 years, I don’t need you tell me whats more effective! I lost more time farting around trying to figure out how to do simple stuff I used to be able to do in my sleep. Again, FAIL

thanks…it helped me…

Thanks for the help. I would not have thought to look in the trust centre.
So that I could disable the plugin I was using I had to run the program as administrator since it was installed for all users. When I did that it worked like a charm.
Thanks again.

XobniRdo.dll does not exist after uninstall but Outlook insists it is trying to load it. It is not listed in the Add-ons or in the options other advanced.

Thanks this was a great help! I couldn’t figure out why it kept saying I had to be an administrator when my login is part of the administrator group.

When I try to enable one note I receive an error message that this can only be done by administrator….I am the administrator and using the proper log in. Know what? All I want to do is be able to send email messages / contacts to a notebook in one note.
ant said on September 14, 2011
For those wondering about Administrator privileges to disable outlook add-ins.
You need to right click on your outlook icon and run outlook as an administrator. Then you will be able to turn off Administrator Protected Add-ins
