Why is Teams Add-in Missing from Outlook?

While it’s possible that you do not see an add-in in the Outlook toolbar because it is collapsed, most of the time, Outlook disables it as it clashes with third-party add-ins or the add-in has executed something that Outlook stopped working.

So, Outlook disables the add-in to prevent further crashes.

Here are the reasons why Teams add-in is missing from Outlook:

Using Old Office Version

You might be using an Office version that doesn’t support Teams integration with Outlook. You need to have Office Professional Pro or Microsoft 365.

To check what Office version you are running, open any Microsoft app like Word or Outlook and go to File > Office Account, and you’ll see your Office version under Product Information.

Add-in Must Support OAuth in Exchange Store

All the add-ins are stored in the Exchange store. The management putting out the add-in and the people using it need to be on the Exchange server with OAuth authentication.

Removed from Group

Add-in will stop showing up if you are removed from a group that the add-in was designated.

Sign in Requirements

You need to sign in to Teams using multi-factor authentication in order to unite Teams with Outlook.

What You Need to CombineTeams with Outlook

You need to use a recent version of Microsoft Office to include Teams add-in to Outlook. You’ll need to run Teams as an admin. It will allow the app to modify the registry. Also, try not to run Outlook with a high priority, which might interrupt COM add-ins.

Here are the prerequisites to unite teams with Outlook:

Software Version Requirements

To use add-ins in Outlook, you need a recent Office 365 or Exchange version. For using the Teams add-in, you must have at least Office 2013, Office 2016, Exchange 2013, and Exchange 2016. Also, keep the Teams app updated.

You should see the Teams option in the Outlook toolbar when you have the correct version. But if you don’t have the option, I’ve provided the solutions for that.

Install Teams as an admin

Adding the Teams add-in to Outlook requires modification of the registry files. So, without the admin privileges, you cannot change the registry, thus unable to include Teams add-in to Outlook.

How to Fix Microsoft Teams not Integrating with Outlook?

Typically, you get the option to associate Teams with Outlook automatically when you install Teams.

But if you don’t see the Teams option in the Outlook toolbar, I’ve given every possible fix that will certainly solve this issue for good.

Here’s how to fix Teams not integrating with Outlook:

1. Reinstall Microsoft Teams

If the Teams app isn’t installed correctly or the files get corrupted, you’ll obviously be unable to include the Teams add-in to Outlook. And the first step should be to uninstall and reinstall Teams.

  • Go to the Compatibility tab.

3. Maintain Order When Launching Apps

This is a weird fix, but it has worked for some users. Running apps without any order should not affect how they behave, but it does.

Microsoft themselves suggested downloading, installing, and signing in to Teams first. Then Teams and restart Outlook. Maintain this order.

Restart both Teams and Outlook if you had to add the Teams add-in to Outlook manually.

4. Enable Teams Add-in

Here are the steps to enable Teams add-in on Outlook:

10. Re-register Teams DLL

You might be having this issue because there was a problem registering the Teams add-in, and you need to re-register. But first, check if the add-in is installed correctly or not.

Here’s how to check the Teams add-in install logs:

  • Copy %LocalAppData%\Microsoft\TeamsMeetingAddin.
  • Click the Search icon and paste it, and hit enter. teams-add-in-folder
  • Open meeting-addin-install-logs.txt.
  • Scroll all the way down and see whether the meeting add-in is installed or not. teams-add-in-installed

If the log says the meeting add-in is now installed, everything is fine, and no need to re-register. But if it doesn’t, you’ll need to re-register.

Here are the steps to re-register Teams DLL:

  • Copy the whole thing in the following line:

C:\WINDOWS\system32\regsvr32.exe /n /i:user “C:\Users\[YourUserName]\AppData\Local\Microsoft\TeamsMeetingAddin\[YourAddinVersion]\x64\Microsoft.Teams.AddinLoader.dll”

  • Put your username between the square brackets and remove the brackets. For me, it is:

C:\WINDOWS\system32\regsvr32.exe /n /i:user “C:\Users\HP\AppData\Local\Microsoft\TeamsMeetingAddin\[YourAddinVersion]\x64\Microsoft.Teams.AddinLoader.dll”

  • Put your add-in version between the square brackets and remove the brackets.

-To get the add-in version

  • Copy %LocalAppData%\Microsoft\TeamsMeetingAddin.
  • Click the Search icon and paste it, and hit enter.

The name of the folder is the add-in version. teams-add-in-version

After completing the command line, it should look something like this,

C:\WINDOWS\system32\regsvr32.exe /n /i:user “C:\Users\HP\AppData\Local\Microsoft\TeamsMeetingAddin\1.0.22147.1\x64\Microsoft.Teams.AddinLoader.dll”

  • Copy your command line.
  • Click the Search icon and paste the command, and hit enter. register-teams-add-in

After going through the steps, you’ll successfully register Teams meeting add-in.
