Teams as default meeting in outlook

This is a common issue — here are the most likely fixes, in order of simplicity:

1. Check the Teams Meeting Add-in is enabled in Outlook

• Go to File → Options → Add-ins
• In the "Manage" dropdown at the bottom, select COM Add-ins → Go
• Make sure Microsoft Teams Meeting Add-in for Microsoft Office is checked
• If it's there but unchecked, enable it and restart Outlook

2. If the add-in is missing entirely

• Open the Teams desktop app and make sure you're signed in
• Fully quit both Teams and Outlook, then reopen Teams first, then Outlook — Teams re-registers the add-in on startup

3. Re-register the add-in manually (if still missing) Open Command Prompt as Administrator and run:

regsvr32 "C:\Users\<YourUsername>\AppData\Local\Microsoft\TeamsMeetingAddin\<version>\x64\Microsoft.Teams.AddinLoader.dll"

Then restart Outlook.

4. Check your default conferencing setting in Outlook Web

• Go to outlook.office.com → Settings (gear icon) → Calendar → Events and invitations
• Under "Online meetings", make sure Teams is selected, not Skype

5. If you're on the new Teams (v2) The new Teams app sometimes loses the add-in registration after updates. Go to Teams Settings → General and toggle off/on the "Register Teams as the chat app for Office" option, then restart both apps.

The most common culprit is #1 or #4 — worth starting there. Let me know what you find.
