Since Microsoft Teams became generally available six months ago, more than 125,000 organizations have discovered how teamwork comes to life in Teams.
Today, Teams is getting even better with the roll out of guest access to all Office 365 commercial and education customers. Now, organizations using Microsoft Teams can provide external access to teams, documents in channels, resources, chats, and applications to their partners, while maintaining complete control over their own corporate data.
How does this affect me?
Microsoft Teams guest access is a tenant-level setting and is turned off by default.
When we make this change, the ‘Pick the license you want to configure’ setting in ‘Settings > Services and Add-ins > Microsoft Teams’, will now have an option for ‘Guest’ with a default value of “off” for the ‘Turn Microsoft Teams on or off for your entire organization’ setting.
In addition, you can use the Azure Active Directory portal to manage guests and their access to Office 365 and Microsoft Teams resources. Microsoft Teams guest access makes use of Azure Active Directory business-to-business (B2B) collaboration capabilities as the underlying infrastructure to store security principles information such as identity properties, memberships, and multi-factor authentication settings.
Guest access in Microsoft Teams is available to you today as part of the Office 365 Business Premium, Office 365 Enterprise, and Office 365 for Education suite licensing.
What do I need to do to prepare for this change?
To enable the full Microsoft Teams guest access experience, you need to enable guest access in Teams and other related key services, such as Office 365 Groups and SharePoint Online.
