How to Uninstall an Outlook Add-in

So, after hitting issues left and right, solving them and posting them on various sites including this one. I had gone dry for a while, there were no issues… I thought to myself “This is too good to be true;” sure enough, it was. However, this is only a minor inconvenience, but one that requires solving none the less.

Being in a corporate environment, it is natural that my company requires that I load Anti Virus software on my machine, Symantec Corporate Edition as the company standard. The installation is simple and straightforward, but being that I have come across a newer version than was provided to me, it was required that I remove the outdated installation.

The uninstall left me wanting as it decided to leave behind a nagging Add-in in Outlook 2007. Every time I open Outlook I am prompted with a pop up that tells me to remove that add-in for Symantec Anti Virus that wasn’t uninstalled automatically.


With no reference to this in “Add or Remove Programs”, or any other obvious way to remove this, I started poking around.  It seems that Office Add-ins are handled within the application and can be removed from the application.  To do so:

  • Go to Tools –>Trust Center within Outlook
  • Click the Add-Ins option on the left side.


Now here is the confusing part.  If you are doing this, you will  notice that there is no add-in reference for Symantec.  You will have to select the option for “Exchange Client Extensions” in the “Manage” drop down at the bottom of the window.

  • Make the selection for “Exchange Client Extensions”
  • Click Go


You will get a new window with a bunch of options and check marks.

  • Uncheck the option for “Symantec Antivirus”
  • Click OK



These instructions apply to other add-ins as well

Sharing your WiFi with friends and family can quickly become a major annoyance. In my household, my son's friends are constantly asking for me to enter the WiFi details so they can hop on and suck the life out of my wireless network. Grabbing each device or phone, navigating the menus, and then typing in my very complex WiFi password is a pain. With a little help from a QR Code, you can sit back, relax, and just point to a QR Code hanging on the wall.
