Outlook 2007: Disabling/Enabling Add-ins

   Posted December 28, 2006 by Jimmy Selix in Microsoft Outlook

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.

    Yeah did the above and I still get the message when I open outlook:

    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.

    hey, every time i open the outlook 2007 i got the following message ( the add-in AVG Extension” cannot be loaded and has been disable by outlook, please uninstall the add-in, and i try the above mentioned solution and it’s not working??

  • CT

    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

      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…

  • Roger

    Thanks ! Microsoft’s way of thinking is getting weirdier each year.

  • Fran Kenfurter

    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

  • raja nakka

    thanks…it helped me…

  • http://billhutchison.org/ billhutchison

    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.

    • Joanne

      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.

  • promytius

    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.

  • Quasimodo_4

    Thanks for the hint.
    My customer thanks you.

    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

    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

  • vikas

  • Gaby

  • Debbie

    When I clicked GO I got a message that only the “administrator” could do this function. How do I get the password for administrator when I’m the only user of my computer?

    • http://blogs.tech-recipes.com Jimmy Selix

      > i would try a blank password if you didn’t remember setting one up. What OS are you using XP or Vista or Win7?

  • Earl Schultz

    Unfortunately this Addin removal is not working for me. Every time I start Outlook 2007 I get a message that the Google Search Addin could not be loaded and was disables. However, when I go to the Addin section of the Trust Centre it does not show the Google Search Addin at all. Also, the path to the Google Search dll does not exist on my computer. I can’t find any way to turn off this error message.

    You should know that I just upgraded from Vista to Win 7 and had to reload a lot of my software so I’m sure this caused the problem. However, if there was an easy way to find where that Addin was trying to load from I could remove it but I don’t see anyway to find this Addin.

    Why does Outlook disable addins with out human intervention?

  • Jet

    The last two days every time I start Outlook 2007 (XP) it freezes so I can’t go into the add-ins. I want to see if the add-ins are the problem or contributing to it.

    Is there another way to reach the add-ins without going through Outlook?

    Any other help or advice would be greatly appreciated.


    • Bill

      > I have an error message when loading Outlook that says it can not load a file that it looks for in add-ons and to go there and delete it. It belongs to a program that would not install due to a bit conflict. I have abandoned the bad program, but am left with this error message each time I bring up Outlook. The file nor the program exist in “Add-in/ons”. How can I stop this error message?

  • Brecht

    Thanks! Resolved my problem!

  • Bev
