11 Ways to Fix Microsoft Teams Not Integrating with Outlook

Outlook and Microsoft Teams are both top-notch productivity programs. You may integrate teams and Outlook if you use both of them to increase productivity even further. Then, you may export a list of team members, convert Outlook meetings into Teams meetings, or utilize Outlook to adjust Teams’ first day of the week. Integrating the Teams add-in into Outlook allows users to jump from Outlook to Teams effortlessly.

When Teams is installed, the interaction with Outlook usually goes smoothly and seamlessly in an automatic manner. However, it’s more complicated than it seems and can go wrong at times, making it prone to errors.

If you are having issues integrating Teams with Outlook, you have arrived at the right destination. This article will outline the causes of your problem, and we’ll then jump on towards the fixes. Remember to follow each fix in a careful manner. If one fix fails to work for you, you can always jump on to the next one. So, without further ado, let’s head right into it.


Why is Outlook missing the Teams Add-in?

While it’s conceivable that an add-in is not visible in the Outlook toolbar because it has collapsed, Outlook typically disables add-ins when they conflict with other add-ins from third parties or when the add-in performs an action that causes Outlook to cease functioning.

Outlook consequently turns off the add-in to stop additional problems.

The following are the causes of Outlook’s unavailability of the Teams add-in:

Due to the old office version

It’s possible that the Office version you’re running doesn’t allow teams to be integrated with Outlook. Microsoft 365 or Office Professional Pro is required.

Open any Microsoft program, such as Word or Outlook, and select File > Office Account. Under Product Information, your Office version will be shown.

Add-in Must Feature Support for OAuth in Exchange Store

The Exchange store houses all of the add-ins. Both the management team that released the add-in and the users of it must be logged into the Exchange server using OAuth authentication.

Requirements

To connect Teams with Outlook, you must sign in to Teams using multi-factor authentication.

Removal From Group

If you are removed from a group for whom the add-in was intended, it will no longer appear.

Requirements for Combining Teams with Outlook

To add Teams add-in to Outlook, you must use a current version of Microsoft Office. Running Teams as an admin is a must. It will enable the application to change the registry. Additionally, avoid running Outlook with a high priority because this might cause COM add-ins to crash.

The requirements to integrate teams with Outlook are as follows:

Software Requirements

You need the most recent version of Office 365 or Exchange to utilize add-ins in Outlook. For example, you need at least Office 2013, Office 2016, Exchange 2013, and Exchange 2016 to use the Teams add-in. Update the Teams app as well.

The Teams option should be visible in the Outlook toolbar when you have the right version. But I’ve given you several alternatives if you don’t have that choice.

Installing Teams as Admin

Modifying the registry files is necessary in order to add the Teams add-in to Outlook. So, if you don’t have admin rights, you can’t modify the registry and hence can’t add the Teams add-in to Outlook.

How Can I Fix Microsoft Teams Not Integrating with Outlook?

When you install Teams, you often have the option to link it to Outlook automatically.

However, if you don’t see the Teams option in the Outlook toolbar, I’ve included every workaround likely to permanently end this problem.

Here’s how to address Teams’ Outlook integration issue:

Run Teams as Admin

It will enable Teams to modify the registry files so that Outlook’s COM add-ins can recognize Teams add-ins.

Here is how to manage Microsoft Teams as an administrator:

  1. Microsoft Teams’ icon should be right-clicked, then choose Properties.
  2. Find your way to the Compatibility tab.
  3. Mark with a checkmark Run this program as an administrator.
  4. Go ahead and apply the changes that were made.

Outlook does not have to be run as an administrator. It is preferable to simply run it normally. You should be able to solve your problem with the help of this solution. Move on to the next one if the problem is still present.

Reinstall Microsoft Teams Application

It goes without saying that you won’t be able to add the Teams add-in to Outlook if the Teams software is improperly installed or if the files get damaged. Reinstalling Teams after uninstalling it should be the first thing you do.

The steps to reinstall teams are as follows:

  1. First of all, tap the Search button.
  2. Next, you must Run the Control Panel by typing it.
  3. In the Programs section, click Uninstall a program.
  4. On the Uninstall menu, choose Microsoft Teams.
  5. Activate your web browser.
  6. Head over to the Microsoft Teams Download page. The Teams version is your choice.
  7. Run the installation file that you downloaded.

After completing these steps, the Teams launcher will download the app and the core files. This repair should help you address your issue. Move on to the following one if the problem is still present.

Enable Teams Add-in

To determine if the Teams add-in is active or not, open Outlook’s add-ins list.

The methods to enable the Teams add-in in Outlook are as follows:

  1. Go ahead and launch Outlook.
  2. Access it by choosing File, then Options, and then Add-ins.
  3. Then, right next to Manage, go ahead and select COM Add-ins and then click Go.

This fix will hopefully assist in the resolution of your issue. Move on to the next one if the problem continues.

Maintain Order While Launching Apps

While this is an odd workaround, several people have reported success with it. The behavior of applications should not be impacted by running them in any particular order; however, it does.

Microsoft itself advised downloading Teams, setting it up, and logging in first. Next, restart Outlook and Teams. Uphold this command. If you have to manually add the Teams add-in to Outlook, restart both Outlook and Teams.

You should be able to solve your problem with the aid of this fix. Move on to the next one if the problem is still present.

Enable Add-in Using Teams Admin Center

In the event that the Outlook add-in was disabled from the Teams admin center, the Teams option would not appear in the Outlook toolbar.

The steps to activate the Outlook add-in from the Teams admin center are as follows:

  1. Go to Microsoft Teams Admin Center in your browser when it has opened. Keep in mind that you need to be an admin to read the page.
  2. Under Meetings, choose Meeting policies.
  3. You should enable the Outlook add-in next.

Hopefully, this fix will have helped you resolve your problem. However, if the issue still persists, jump on to the next one.

Hopefully, this remedy will assist you in solving your issue. However, if the problem is still present, move on to the next.

Edit User Profile Disk Settings

By excluding the following folders from the user profile drive, a few users were able to resolve this problem:

  • AppData\Local\Microsoft\Teams
  • AppData\Local\Microsoft\TeamsMeetingAddin
  • AppData\Roaming\Microsoft\Teams.
  • AppData\Local\Microsoft\TeamsPresenceAddin

At each login, the computer essentially reinstalls Teams. See if you can also get this to work.
