Teams Add-on Disabled on New Outlook for Windows

Overview

The New Outlook for Windows (the Outlook app with the New Outlook toggle turned on) does not use COM add-ins or the registry settings used by Outlook Classic. Add-ins in New Outlook are cloud-based web add-ins that are tied to your account, so the fixes are different. If the Teams Meeting button is missing or the add-in appears disabled, work through the sections below.

Not sure which Outlook you are using? If the top of the window shows a New Outlook toggle that is switched on, you are using New Outlook. If you are using Outlook Classic, see the separate article Teams Add-on Disabled on Outlook Classic.

This article includes steps for both average users and tech professionals. If you need additional help, see the Need Help section.

Symptoms

• The Teams Meeting button is missing when creating a new event or meeting invite.
• The Teams Meeting add-in is not listed or shows as turned off under Add-ins.
• New meetings are not automatically given a Teams link.

Applies To

• New Outlook for Windows (Microsoft 365)
• Windows 10 and Windows 11

Section 1: Check the Online Meeting Settings

1. In New Outlook, click the Settings (gear) icon in the upper right.
2. Go to Calendar > Events and invitations.
3. Confirm that Online meeting provider is set to Microsoft Teams.
4. Optionally, turn on Add online meeting to all meetings so every new meeting includes a Teams link.
5. Click Save, then create a new event and check for the Teams Meeting toggle.

Section 2: Check the Add-in Is Turned On

1. In New Outlook, open a new calendar event.
2. On the ribbon, click Apps (or the ... menu > Add-ins).
3. Open My add-ins and look for Microsoft Teams Meeting.
4. If it is listed but turned off, turn it on. If it is not listed, continue to Section 3.

Section 3: Update, Sign Out, and Restart

1. Close New Outlook completely.
2. Open the Microsoft Store, go to Downloads, and click Get updates to install any Outlook updates.
3. Reopen New Outlook. If the issue continues, go to Settings > Accounts (or click your profile picture) and sign out, then sign back in with your work account.
4. Create a new event and check for the Teams Meeting button.

Section 4: Test in Outlook on the Web

Technician-level step. This isolates whether the problem is with the app or with the account/tenant.

1. Sign in at outlook.office.com with the affected account.
2. Create a new calendar event and check for the Teams Meeting option.
3. If it is also missing on the web: the issue is at the account or tenant level. Go to Section 6.
4. If it works on the web: the issue is local to the New Outlook app. Go to Section 5.

Section 5: Repair or Reset New Outlook

Technician-level step. Resetting clears the local cache; the mailbox itself is not affected, but the user will need to sign in again.

1. Close New Outlook.
2. Go to Settings > Apps > Installed apps and find Outlook (new).
3. Click the ... menu > Advanced options.
4. Click Repair first and test. If the problem persists, click Reset.
5. Reopen New Outlook, sign in, and verify the add-in.

If the repair and reset do not help, remove the account from New Outlook (Settings > Accounts), then add it again.

Section 6: Tenant/Admin Checks

Admin-level step. Requires Microsoft 365 admin or Teams admin permissions.

• Teams meeting policy: In the Teams admin center, confirm that the user's meeting policy allows the Outlook add-in (AllowOutlookAddIn is True). This can also be checked with PowerShell:

  Get-CsTeamsMeetingPolicy | Select Identity, AllowOutlookAddIn

• Integrated apps: In the Microsoft 365 admin center, go to Settings > Integrated apps and confirm the Microsoft Teams Meeting add-in is deployed and assigned to the user.
• Default online meetings: If new meetings are not getting Teams links automatically, check the organization setting:

  Get-OrganizationConfig | Select OnlineMeetingsByDefaultEnabled

• Policy propagation: Policy changes can take several hours (up to 24) to apply. Have the user sign out and back in after changes.

Additional Notes

• The registry edits and regsvr32 steps used for Outlook Classic do not apply to New Outlook.
• If you depend on COM add-ins or other features that New Outlook does not support, you can switch back to Outlook Classic using the New Outlook toggle mentioned in the Overview section.
