The Teams Meeting button is missing from Outlook for one user. The Teams desktop application is installed, and the user can create meetings directly from the Teams calendar.

Other users on the same network can see the button in Outlook.

    Dear Ava Thompson,

    Based on your description, since the user can create meetings directly from the Teams desktop app but the Teams Meeting button is missing only in Outlook, the issue is typically related to the Teams Meeting add-in for Outlook rather than the Teams service itself. Could you let me know whether the affected user recently changed accounts, licenses, or devices?

    In the mea time, please try the following checks:

    1. Verify the Teams Meeting Add-in is enabled
      • In Outlook, go to File > Options > Add-ins.
      • At the bottom, select COM Add-ins and click Go.
      • Confirm that Microsoft Teams Meeting Add-in for Microsoft Office is listed and checked.
    2. Check if the add-in is disabled
      • Go to File > Options > Add-ins.
      • Select Disabled Items from the Manage drop-down and click Go.
      • If the Teams add-in appears, re-enable it and restart Outlook.
    3. Confirm Outlook and Teams are using the same account
      • The Teams Meeting button may not appear if Outlook is connected to a different account or mailbox than the one signed into Teams.
    4. Restart Teams and Outlook
      • Fully exit both applications (including from the system tray), then start Teams first and Outlook afterward.
    5. Re-register the Teams add-in
      • Sign out of Teams, close Teams and Outlook completely, then sign back into Teams and allow it a few minutes to re-register the Outlook integration.
    6. Check Outlook client type
      • If the user is using the New Outlook for Windows, verify that Teams integration is supported and enabled. If necessary, test in Classic Outlook to determine whether the issue is specific to the Outlook client.

    I hope it meets your expectations, feel free to reach out if you have any update.

    For a single affected user, the most likely causes are that the Teams Meeting add-in is missing, disabled, or Outlook and Teams are not running in the same sign-in/runtime context.

    1. Verify the user is on a supported setup:
      • Windows with Outlook Classic, Outlook 2013 or later.
      • Teams desktop client installed on the same machine.
      • Signed in with a work or school account that has a Teams license.
      • The add-in is not supported for personal Outlook.com scenarios, POP/IMAP accounts, or Microsoft Store Office installs.
    2. Check whether the add-in is installed and enabled in Outlook:
      • In Outlook, go to File > Options > Add-ins.
      • Under Manage, select COM Add-ins > Go.
      • Look for Microsoft Teams Meeting Add-in for Microsoft Office.
      • If it is present but unchecked, check it and select OK.
    3. If Outlook disabled the add-in, re-enable it:
      • In Outlook, go to File > Options > Add-ins.
      • Under Manage, select Disabled Items > Go.
      • If Teams appears there, select it and choose Enable.
      • Restart Outlook.
    4. Make sure Outlook and Teams are running in the same context:
      • Right-click the Outlook and Teams shortcuts.
      • Open Properties > Compatibility.
      • Confirm Run this program as an administrator is unchecked for both apps.
    5. Restart in the correct order:
      • Fully quit Outlook.
      • Quit Teams from the system tray.
      • Start Teams first and sign in.
      • Then start Outlook.
    6. If the user recently moved to new Teams and the add-in is missing entirely:
      • Open Settings > Apps > Installed Apps.
      • Find Teams Meeting Add-in and uninstall it.
      • Close Outlook.
      • Quit Teams from the system tray.
      • Restart new Teams.
      • Wait until Teams Meeting Add-in appears again in installed apps, then restart Outlook.
    7. If the user is on new Outlook instead of classic Outlook:
      • There is no separate add-in to install.
      • The meeting form should show a Teams meeting toggle.
      • To reinitiate integration, close Outlook, quit Teams, start Teams and sign in, then start Outlook.
      • The user must be signed in to both Outlook and Teams with the same work or school account and use the new Teams client.

    If the add-in still does not appear after these steps, reinstalling the Teams desktop client is a supported next step to re-register the add-in.
