Sometimes, Outlook Add-ins can decide to behave badly and cause all sorts of issues with your Outlook – commonly in the form of annoying pop-up boxes. Since Outlook does not need Add-ins to run, disabling the Add-in is a quick and easy way to stop the errors.
Step 1 – Open your Outlook 2010 program, and in the top left corner of the screen, click the orange “Home” tab.
Step 2 – On the left hand side, click “Options“.
Step 3 – On the new popup window, on the left side click “Add-Ins”
Step 4 – At the bottom of the screen, make sure that “COM Add-Ins” is selected, then click the “Go” button.
Step 5 – On the new popup screen, find the Add-In name that is giving you trouble, and un-tick it. Then select OK.
Step 6 – Close down your Outlook program completely, and reopen in. Test to see if the problematic Add-in has stopped performing.
