Important updates to Guest Access defaults in Teams starting in February 2021
Published Feb 05 2021 10:27 AM 9,784 Views

In Teams support, we often receive questions from customers seeking help when working with Guests – especially from new tenants. You can guess how excited we are to see Guest Access be enabled by default in Teams for new tenants starting on February 8, 2021. This default behavior follows the rest of the Office 365 suite where Guest Access is already enabled, so this should empower new tenants to collaborate with greater ease, while also still supporting the same deep controls to adjust guest settings to fit individual organizations’ needs.


With this being a support focused blog, let's talk about some things that customers may have questions about related to Guest Access being enabled by default.


The biggest question is – what is going to happen?


  • Until February 2021, guest access is still turned off by default. You must turn on guest access for Teams before admins or team owners can add guests. After you turn on guest access, it might take a few hours for the changes to take effect. If users see the message Contact your administrator when they try to add a guest to their team, it's likely that either guest access hasn't been turned on or the settings aren't effective yet.


  • After February 2021, guest access in Microsoft Teams will be turned on by default for new customers & existing customers who haven't configured this setting. When this change is implemented, if you've not already configured guest access capability in Microsoft Teams, that capability will be enabled in your tenant. If you want guest access to remain disabled for your organization, you'll need to confirm that the guest access setting is set to Off instead of Service default.

If you are signed into your M365 Tenant Admin Portal as an Admin you can also review the information in Message Center Post 234252.
