You joined the Teams call, someone said “we’ll send notes after,” and you already know nobody will. You want Otter in the room so you can actually listen. Here is how to set up Otter AI for Microsoft Teams, and what to do when it will not join.
The short answer: connect your Outlook calendar to Otter, turn on auto-join for the meetings you want, and ask your Teams admin to allow guests to join. Otter’s notetaker enters Teams meetings as a guest, and that one admin setting is where most setups fail.

What you need before you start
- An Otter account (a free plan exists, but check Otter’s current limits on its pricing page before you rely on it).
- A Microsoft 365 Outlook calendar. Otter says it supports the online Microsoft 365 calendar, not on-premises Exchange (Otter calendar help).
- A Teams meeting link in the calendar event. Otter shows its toggle only on events with a valid Zoom, Google Meet or Microsoft Teams link.
- Someone who can change Teams meeting settings, if you are not the admin yourself.
Connect Otter to your Microsoft calendar
- In Otter, open Apps (or Integrations) and click Add or Connect next to Microsoft.
- Sign in to your Microsoft account and accept the permissions.
- Wait for your events to appear on the Otter home calendar.
If Microsoft says you need admin approval, that is your IT team’s call. Otter itself suggests asking the admin to grant the calendar permissions first, which saves a lot of back and forth.
Let the notetaker into Teams meetings
This is the step people skip. Otter’s notetaker cannot sign in with your company account. It joins as an anonymous guest, so your organisation has to allow that. According to Otter’s Teams setup guide, an admin needs to:
- Open the Teams admin center, go to Meetings, then Meeting settings, and turn on “Anonymous users can join a meeting.”
- Go to Meetings, then Meeting policies, and turn on “Anonymous users can join a meeting unverified.”
Two optional settings make it smoother: letting people in your org and guests bypass the lobby, and setting external bots to “Do not detect bots.” Skip them if your security team says no. You will just admit the notetaker by hand.
Choose which meetings Otter joins
On the Otter home calendar, each Teams event has a toggle. Otter’s auto-join options let you pick all meetings with a video link, only meetings you host, only external meetings, only internal ones, or only the ones you toggle yourself.
My advice: start with “only meetings I select.” Add one meeting, see how it behaves, then widen it. If you forget, you can add the notetaker mid-meeting from the microphone icon on the event.
“Notetaker failed to join”: what is going on
If you see “This meeting is not being recorded. Notetaker failed to join,” Otter says the cause is usually a Teams policy that blocks anonymous guests. Check this in order:
- The two anonymous-guest settings above are on.
- The meeting is hosted by your organisation or one where guests are allowed. An outside organiser’s settings apply there, not yours.
- The lobby is not holding the notetaker. Someone with permission needs to admit it.
What people in the meeting will see
Otter says the notetaker cannot join invisibly. It shows up in the participant list. Tell people before you hit go, and follow your company’s rules and the local recording laws. In practice, one line in the invite works: “I will have an AI notetaker in this call so I can focus on you.”
How to use Copilot in Teams for meeting notes instead
If your company already pays for Microsoft’s own tools, you may not need a guest bot at all. Microsoft’s intelligent recap needs a Teams Premium or Microsoft 365 Copilot licence, and transcription has to be turned on for the full recap (Microsoft Learn). Copilot also does not work in meetings hosted outside your own organisation (Microsoft Support).
So the split is simple. Internal meetings and a Copilot licence: use the built-in recap. Client calls hosted by someone else, or no licence: Otter is the option you control yourself, as long as guests are allowed. For a wider comparison, see our honest comparison of AI note takers.
Turn the notes into something useful
A transcript is not a result. After the call, paste the Otter summary into your chat assistant and ask for owners and deadlines. Our guide on summarizing meeting notes with ChatGPT has a prompt for it, and the AI meeting minutes generator page covers the formal version. If you live in Google’s apps, Gemini for meeting notes is the other route. Planning the next call? Try the AI meeting agenda guide.
Quick answers
Does Otter work with Microsoft Teams?
Yes. Otter lists Microsoft Teams next to Zoom and Google Meet as a supported meeting platform, once your calendar is connected and guests are allowed.
Do I need to be the meeting host?
No. You can set auto-join for meetings you host or for any calendar event with a Teams link. The meeting’s own guest settings still decide whether the notetaker gets in.
Is it free?
Otter has had a free plan, but limits change. Check Otter’s pricing page today before you plan a whole workflow around it.
