Teams Add-in not showing in Outlook

Every single time MS runs an Office update Teams gets lost and can't be used. This time I had a client meeting and couldn't open the meeting for the client to join. I had to log into Zoom and start a meeting there. Last time MS updated Office Outlook forgot all my account settings and I had to do a system restore. I called support, but they couldn't fix it and eventually just ghosted me. MS is really bad for small business. I'm going to move to Google. This was truly embarrasing. Please do better.

I think there are two separate issues being described here. There is a known issue with the add-in for new Teams but we are experiencing this issue with classic Teams (v1.6). Is anyone else experiencing an add-in issue with classic Teams?

Fabulous !! this resolved my issue. Reinstalled office and new teams multiple times but same trouble. But getting message to update to new team or it will be updated automatically and I can't stop it.

Had anyone else implemented the below in order to stop Outlook from inserting Teams meeting links into every calendar event? Probably unrelated but grasping at straws.

Set-OrganizationConfig -OnlineMeetingsByDefaultEnabled $False

I just got a notice from o365mc@microsoft.com - Classic Teams Users Will be Automatically Updated to New Teams After March 31, 2024 - they'd better have the outlook addin issue fixed by then!

On October 5, 2023, we announced general availability of the new Microsoft Teams app for Windows and Mac. Read the message center post MC679451 for details.

We mentioned in our GA announcement that classic Teams users will be automatically updated to new Teams in the coming months. Today, we want to inform you that after March 31, 2024, any classic Teams users who have not updated to new Teams, will be automatically updated to new Teams.

With just one click, you can join millions of users who are relying on new Teams to stay connected with colleagues, partners, and customers.

How will this affect your organization?

• New Teams is a performance-focused update. New Teams is up to 2x faster and use 50% less memory. There is no major impact to the user experience for new Teams. This means you don’t need to invest in any additional training.
• Between now and March 31, 2024, you can continue to use classic Teams without interruption.

We encourage you to review the service agreementthat governs Teams app updates.

If you haven’t already updated to new Teams yet, review the prerequisites and policy updates for the update to new Teams.

How can I prepare for a seamless update to new Teams?

• Admins can enable new Teams in their organizations by leveraging robust IT admin policies and taking advantage of deployment options such as office update channels that allow them to enable users and groups within their organizations as needed.
• Admins who currently have the Teams update policy set to 'Not enabled' for the 'Use new Teams client' setting, we suggest setting the value as ‘New Teams only’ after selecting the Teams update policy to ‘Microsoft controlled’ in the Teams admin center.

Notes:

• We have not made the new Teams in the Virtual Desktop Infrastructure (VDI) environment generally available yet, so the VDI users will not be affected by the auto-update timeline of March 31, 2024.
• Microsoft Teams Rooms (MTR) and Surface Hub devices will also not be affected by the March 31, 2024, timeline.
• For our education users, the update option to new Teams is available now and they can be seamlessly updated at any time. Please visit this page for more information.
