Additional meeting and call-related features and issues within Microsoft Teams for business
Interpreters in Teams language interpretation must join on Teams for desktop. Language selection is not available on Teams for web or mobile. Interpreters also have attendee permissions, and an interpreter can’t be an organizer or co-organizer.
For webinars, external presenters can be added, and they receive a unique join link. If the external presenter is joining as a guest, they must sign in with their guest account. If they were invited as an external presenter, their unique presenter link only works when they are signed in to Teams with the same email address that received the join link. They can’t sign in with a different account and use that link, and they can’t join anonymously with that presenter link.
For the setup:
- In the webinar, add each interpreter as an external presenter:
- Teams calendar → select the webinar → View event → Manage event → Add external presenters.
- Enter the interpreters’ external email addresses.
- Select Save and send invites.
- Have each interpreter join using the unique join link sent to that same external email address.
- If testing with a personal Gmail account, the account signed in to Teams must match the email address that received the unique presenter link.
- Make sure each interpreter joins from the Teams desktop app.
- Language interpretation is not supported for interpreters joining on Teams for web.
- If the interpreter still does not appear as assignable for interpretation, verify the person joined as the intended external presenter account and not with a different signed-in identity.
A key limitation in the available guidance is that it does not document assigning an external presenter to an interpreter role during a webinar. It only confirms that language interpretation is supported in webinars, that interpreters must use Teams desktop, and that external presenters can join webinars with their unique presenter links.
