Teams add-on for Outlook missing

Dear @Jordan Stoick, 

Thank you for posting your question in the Microsoft Q&A forum and I understand you’re unable to add a Teams meeting link when creating a calendar invite in Outlook. 

To help me better understand the situation and assist you effectively, could you please share a few details such as:    

1/ Are you currently using New Outlook (app or web) or Classic Outlook? 

2/ When you create and send a calendar invite in Outlook, what exact steps do you follow to perform this action? (Which buttons or menu options do you click?) 

3/ Could you share a screenshot of the area where the Teams add-in is missing, as you mentioned? 

4/ What Outlook version are you using? 

• In Classic Outlook, you can check this under File > Office Account > About Outlook. 

• In New Outlook, go to Settings > General > About Outlook. 

This will help us better understand the context and provide more targeted support. Any additional information will help us better understand and support you.     

To help you understand how to create and send a Teams meeting invitation in both Classic Outlook and New Outlook, please review the instructions below: 

• Classic Outlook: 

Go to the Home tab. 

Select New Items > Meeting. This will open a meeting compose window. 

Enter the required meeting details. 

Click Send to deliver the meeting invitation to all attendees you added. 

• New Outlook (web & desktop): 

Open New Outlook, then switch to the Calendar tab. 

Double-click the date you want to schedule a Teams meeting or click New Event and select Event. 

Turn on the Teams meeting toggle to convert the event into a Teams meeting. 

Add your meeting information and click Save. 

Once saved, the meeting invitation will be automatically sent to all attendees.

If the Teams meeting add-in is missing from Outlook, you can follow these troubleshooting steps:

If the Teams meeting add-in is missing from Outlook, you can follow these troubleshooting steps:

1. Close both Outlook and Teams: Ensure that both applications are completely closed before proceeding.
2. Restart Teams: Open the Teams client and sign in.
3. Restart Outlook: After signing in to Teams, open Outlook again.
4. Check Add-ins: In Outlook, go to File > Options > Add-ins. Look for the Microsoft Teams Meeting Add-in for Microsoft Office in the Active Application Add-ins list. If it’s not there, check the Disabled Application Add-ins list and enable it if found.
5. Verify Installation: Ensure you have the correct version of Office installed (Office 2013, 2016, 2019, or 2021) and that you are not using the Microsoft Store version of Office, as it does not support the Teams add-in.
6. Registry Settings: If the add-in still doesn't appear, check the registry settings to ensure the LoadBehavior entry for the add-in is set to 3. You can find this under HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\Outlook\Addins\TeamsAddin.FastConnect.
7. Run Diagnostics: As an administrator, you can run the Teams Add-in Missing in Outlook diagnostic in the Microsoft 365 admin center to verify that the affected users have the correct policies to enable the Teams Outlook add-in.

If these steps do not resolve the issue, consider reinstalling the Teams meeting add-in or checking for any updates to Outlook and Teams.
