Symptoms

No 'New Teams Meeting' button in the Outlook calendar, the Teams Meeting toggle is missing from new meetings, or the add-in is listed as inactive/disabled.

Why it happens

• Update to new Teams didn't install the Teams Meeting add-in
• Outlook disabled the add-in after a slow load or crash
• Using new Outlook for Windows, which doesn't support COM add-ins
• Calendar belongs to an account not signed in to Teams
• Service update incompatibility (users still reported it in July 2026)
