When you install Microsoft Office or other software on your PC, several add-ins are automatically installed and registered, but not all of them are useful enough to keep. Add-ins are the functionality tools installed on your PC to add custom commands to your programs. While most add-ins are useful and designed to increase your productivity, some are useless or outdated and may clutter your PC unnecessarily. These outdated add-ins may probably cause deadlocks and raise compatibility issues, too. In this post, we will learn how to enable, disable or remove Microsoft Outlook and Outlook (new) add-ins.
Enable or disable MS Outlook add-ins
To look for Outlook add-ins in Outlook, open your Outlook desktop client and click on the red Windows Store icon you see.

A popup will open offering you all the available add-ins for Outlook. To install them, simply move the slider to the On position and restart Microsoft Outlook. In some cases, you will see a Get it button instead of the slider. To install it click on this button to commence its installation. Restart Outlook to enable it.
Or in the New email window, you will see an Office add-ins link.
