How to Fix Missing Microsoft Teams Add-in for Outlook in Windows 10

Looking for easy ways to find missing Microsoft Teams Add-in for Outlook in Windows 10?

The Microsoft Office suite includes a number of useful features that are designed to make users’ work life easier. With its ability to adapt to your needs, it is one of the best applications that enables users to reach their business and personal goals. 

One such amazing feature of Office is the Add-ins feature that makes switching from one application to another easier. We find this particularly helpful when we want to schedule Teams meetings in Outlook but recently, several users reported that they cannot find the Microsoft Teams Add-ins for Outlook in Windows 10. 

We had a look into this matter and found out that this issue can be caused by a number of reasons, including outdated office installation, corruption errors, lack of multi-factor authentication. 

If you are facing a similar issue, you are in the right place because, in this guide, we have listed some of the most effective methods to resolve the error under consideration. 

Let’s get started. 

1. Register Microsoft Teams DLL Files.

DLL files are program files that contain instructions that other software can use to perform certain tasks. However, the DLL files must be registered for certain programs to create a path to the program’s file in the registry where it can be looked up. 

Several users managed to resolve the issue of missing Microsoft Teams Add-ins by registering Microsoft Teams DLL files on their PC, which is why we encourage you to give it a shot. 

Here is what you need to do:

  1. Type This PC in the search bar and click on Open.
  2. Inside the newly launched window, navigate to the location mentioned below. Keep in mind that the address may vary according to the version of Microsoft Teams on your PC. 
C:\Users\<your user name>\AppData\Local\Microsoft\\Teams\TeamsMeetingAddin\1.0.20244.4\x86
  1. Locate Microsoft.Teams.AddinLoader.dll in the window. 
  2. Once you have found it, type cmd in the search bar and hit click on Run as administrator to launch elevated Command Prompt.
  3. Now paste the command mentioned below in the Command Prompt window and hit Enter. The command we are using is similar to the path mentioned in Step 2. In case the path to Microsoft.Teams.AddinLoader.dll on your PC is different, you must type that in Command Prompt. 
C:\Users\<your user name>\AppData\Local\Microsoft\\Teams\TeamsMeetingAddin\1.0.20244.4\x86
  1. Next, copy the command mentioned below and paste it into the Command Prompt window. Hit Enter to execute the command.

  2. Finally, restart your PC to save the changes.

2. Enable Essential Add-ins.

When Outlook detects that certain features are interfering with its regular operations, it disables them. This can also occur with Add-ins, and there is a chance that Outlook itself disabled the Add-ins that caused the error.

If this is the case, all you need to do is simply enable the Add-ins back by modifying Outlook settings.

Here is how you can do that:

  1. Type Outlook in the search bar and click Open to launch the program.
  2. Locate the File option and click on it.
