If someone outside of SCU invites you to a meeting using Microsoft Teams, you will be able to attend, even though Teams is turned off in SCU’s Microsoft 365 service.
If someone outside of SCU invites you to be a guest in their Microsoft 365 service, these limitations will not affect you.
To log in as a guest to another organization’s Microsoft 365 service, continue to use the link on the invitation they sent you. You may need to open the invitation in a "Private Browsing" or an "Incognito" window in your browser. You will not go through SCU’s SSO when you access another organization’s Microsoft 365 service.
