According to our official documentation, in Teams, you may receive a message telling you why you can't enter the meeting. For the message you encounter and the solution, please refer to:
"Sign in to join this meeting"
If you're seeing this message, the meeting does not allow people to join who are not signed in with their Teams work or school account, including those who are joining from Teams for personal use. You might need to take extra steps to join:
- If you're joining from a meeting link or incognito window as an anonymous user, make sure you're signed into your work or school account.
- If you're the meeting organizer and you want to allow people who are not signed in to join your meeting, contact your IT admin to change the meeting settings or meeting policy assigned to you (learn more here). Changes from your IT admin may take up to 24 hours to be reflected.
"Sign in with a different account to join this meeting"
If you're seeing this message, the admin settings of your organization or the admin settings of the meeting organizer's organization don't allow for meetings between your organizations. You might need to take extra steps to join:
- If you're already signed in, try joining from another work or school account. Make sure you're signed into the account the invite was originally sent to.
- If you're the meeting organizer and you want to allow people who are from another organization to join your meeting, contact your IT admin to set this up for you (learn more here). Changes from your IT admin may take up to 24 hours to be reflected.
