So, what are guest accounts? Think of them as special passes for external people, allowing them to join your team's collaboration. It's like sending invitations to partners, clients, or friends to join in the collaborative activities.

Why should you care? Guest access is not just a fancy feature; it's your ticket to smoother collaboration. Understanding why it's important is crucial for making the most of it.

  • Teamwork Upgrade: Guest accounts break down barriers, letting external individuals collaborate with your team, boosting productivity.
  • No More Hiccups: Whether working on documents in SharePoint or having a chat in Teams, guest access means everyone can contribute without any hassle.
  • Global Hangouts: Expand your collaboration globally by connecting with clients, vendors, and more – all within Microsoft 365.

But, hold on! While guest access is a game-changer, keeping things secure is a top priority. It's about finding the right balance between being welcoming and maintaining control. In this first blog post, we'll delve into the basics of keeping those guest accounts safe, addressing concerns, and sharing some top-notch tips to keep your information secure.

Understanding External Access in Microsoft 365

Microsoft 365 is your partner for enhancing collaboration, allowing you to connect with the outside world through file sharing, team invites, meetings, and chats. Let's break down how external individuals can access your Microsoft 365 features:

Activity Account Type Default Setting
Authenticated file and folder sharing Guest account Enabled
Site sharing Guest account Enabled
Team sharing Guest account Enabled
Shared channel in Teams Existing Microsoft 365 external account Disabled
External chat and meetings Existing Microsoft 365 external account Enabled
Anonymous meeting join None Enabled
Unauthenticated file and folder sharing None Enabled

Authenticated file and folder sharing: When sharing files, sites, or teams with individuals outside your organization, Guest Accounts take the spotlight. They are like your backstage passes – enabled by default and ready to go. Guests can only access what you specifically share with them.

Shared channel in Teams: Teams' shared channels are the VIP lounge for your collaborations. They exist, but you need to enable external organizations to join. It uses Microsoft Entra ID (Azure AD) B2B direct connect, allowing individuals from other Microsoft 365 organizations to join without needing a guest account.

External chat and meetings: Your organization's team can communicate with outsiders through chats, meetings, and video calls in Teams. By default, it's open to all other Microsoft 365 organizations, but you can customize it. No need for guest accounts here; outsiders can stay in their own environment and still connect with your organization.

Anonymous meeting join: External individuals can join meetings anonymously – no strings attached. It's like wearing a mask to the party, but you have the controls to manage this masked meetup.

Unauthenticated file and folder sharing: Unauthenticated sharing allows you to share files and folders without requiring logins. It's like sharing secret links for anyone to click. Keep in mind, you can revoke access by pulling the link at any time.
