# Re-enable plugin in Outlook

## Introduction

This document explains how to reactivate the Zivver Office Plugin when Outlook has disabled it. You can recognize this by the notification: “Outlook has disabled the plugin.” Outlook may disable a plugin if it slows Outlook down—even by just a few milliseconds. By manually re-enabling the plugin, you indicate that you would like to continue using Zivver.

## Re-enable the plugin

1. Click **File** at the top left of Outlook.
2. Click **Slow and Disabled COM Add-ins**.

_A new window opens._
3. Locate the Zivver Office Plugin in the list.
4. Click **Always enable this add-in**.

_The plugin is now enabled. You can send and read Zivver messages._
