Add-ins play a crucial role in extending Outlook\u2019s capabilities on your PC. They not only offer features to improve your productivity but also help you streamline daily tasks. However, what if these Outlook add-ins go missing or stop working on your Windows 10 or 11 PC?<\/p>\n\n\n\n

Whether you\u2019re experiencing issues with a specific Outlook add-in such as Teams<\/a>, or with all of them, this guide will help. Work your way through the following tips to fix issues with Outlook add-ins and get them working on your PC.<\/p>\n\n\n\n

1. Restart Microsoft Outlook<\/h2>\n\n\n\n

Outlook, like any other app, can experience issues while launching or running on your Windows computer. When this happens, some of your Outlook add-ins may not show up or work as expected. In most cases, you can fix such issues by simply restarting the Outlook app.<\/p>\n\n\n\n

Press the Ctrl + Shift + Esc keyboard shortcut to access the Task Manager. In the Processes tab, locate and select Microsoft Outlook. Then, click the End task option at the top.<\/p>\n\n\n\n

\"Close<\/figure>\n\n\n\n

Open the Outlook app again and check if the issue is still there.<\/p>\n\n\n\n

2. Make Sure the Add-In Is Enabled<\/h2>\n\n\n\n

One possible reason for an Outlook add-in to disappear is if it has been disabled, either by the user or system administrator. If that\u2019s the case, you can use these steps to restore the missing Outlook add-in on your Windows PC.<\/p>\n\n\n\n

Step 1:<\/strong> Open the Microsoft Outlook app on your PC and click the File menu at the top-left corner.<\/p>\n\n\n\n

\"Outlook<\/figure>\n\n\n\n

Step 2:<\/strong> Select Options from the left pane.<\/p>\n\n\n\n

Step 4:<\/strong> Select the add-in you want to restore and click the Enable button.<\/p>\n\n\n\n

\"Enable<\/figure>\n\n\n\n

3. Update the Outlook App<\/h2>\n\n\n\n

By default, Office apps including Outlook install newer updates automatically on your Windows PC. However, if you have disabled automatic updates for Office apps<\/a>, you might be running an outdated version of Outlook, which can sometimes result in performance niggles.<\/p>\n\n\n\n

To update the Outlook app manually:<\/p>\n\n\n\n

Step 1:<\/strong> Open the Outlook app and click the File menu at the top-left corner.<\/p>\n\n\n\n

4. Scan Outlook Data File<\/h2>\n\n\n\n

Issues with Outlook data files<\/a> on your PC can also cause your add-ins to go missing or stop working. Fortunately, Microsoft includes a tool that can find and repair problematic Outlook data files automatically. Here’s how to run it.<\/p>\n\n\n\n

Step 1:<\/strong> Press the Windows + E keyboard shortcut to open File Explorer and navigate to the following folder.<\/p>\n\n\n\n

C:\\Program Files\\Microsoft Office\\root\\Office16<\/pre>\n\n\n\n

After completing the above steps, check if your add-ins work.<\/p>\n\n\n\n
5. Modify Registry Files to Prevent Outlook From Disabling Add-Ins<\/h2>\n\n\n\n
At times, Microsoft Outlook may disable an add-in if it causes the app to run slowly or crash. If you don’t want that, you can modify a few registry files to stop Outlook from automatically disabling add-ins.<\/p>\n\n\n\n
Since registry files contain important files for Windows, it\u2019s important to back up all the registry files<\/a> or create a restore point<\/a> before proceeding.<\/p>\n\n\n\n
Step 1:<\/strong> Press the Windows key + R to open the Run dialog box. Type regedit<\/em> in the box and press Enter.<\/p>\n\n\n\n

\"Registry<\/figure>\n\n\n\n
Step 3:<\/strong> Locate the add-in you don\u2019t want Outlook to turn off and copy its name. <\/p>\n\n\n\n
\"Copy<\/figure>\n\n\n\n
Step 4:<\/strong> Paste the following path in the address bar at the top and press Enter.<\/p>\n\n\n\n
HKEY_CURRENT_USER\\Software\\Policies\\Microsoft\\Office\\16.0\\Outlook\\Resiliency\\AddinList<\/pre>\n\n\n\n
Step 5:<\/strong> In the right pane, right-click anywhere on an empty spot and select New > String Value. Name it with the add-in key name copied earlier.<\/p>\n\n\n\n
\"Create<\/figure>\n\n\n\n
Step 6:<\/strong> Double-click the newly created string value, enter 1 in the text box and click OK.<\/p>\n\n\n\n
\"Edit<\/figure>\n\n\n\n
6. Run the Office Repair Tool<\/h2>\n\n\n\n
If all else fails, you can run the Office repair tool on Windows to fix issues that may be causing the Outlook add-ins to misbehave. Here are the steps for the same.<\/p>\n\n\n\n
Step 1:<\/strong> Press the Windows + R keyboard shortcut to launch the Run command. In the Open field, type appwiz.cpl<\/em> and press Enter.<\/p>\n\n\n\n
\"Open<\/figure>\n\n\n\n
