Microsoft Teams is a collaboration platform that integrates with Microsoft 365 services and allows organizations to enhance productivity. Teams can be used with people both inside and outside your organization. Enabling guest access in Microsoft Teams allows individuals who are not part of your organization to participate in teams and channels, collaborate on documents, and attend meetings.
Guest access in Teams is a tenant-level setting in Microsoft Azure Active Directory (Azure AD) and can be controlled by the Azure AD admin center. Admins can configure guest access settings to ensure compliance with their organization’s security policies.
Here’s how to configure guest access to Microsoft Teams using the Azure AD admin center:
Navigate to https://aad.portal.azure.com and sign in using an account with admin permissions.
On the left-hand navigation pane, click on “External Identities” to manage the settings for external users in Azure AD.
Within the External Identities section, select “External collaboration settings”. Here, you can manage how guests can interact with your organization.
In the external collaboration settings, configure the settings that affect guest user permissions. For example:
Ensure to tailor these settings in line with what is suitable for your organization.
Proceed to the Teams admin center by navigating to https://admin.teams.microsoft.com. In the Teams admin center, go to “Org-wide settings” and then click on “Guest access”. Set the “Allow guest access in Teams” option to On. This setting must be enabled to allow guest access in Teams specifically.
Below the main setting to “Allow guest access in Teams,” you can configure what guests are allowed to do within Teams, including:
After configuring your settings, ensure to click on “Save” to apply the policy changes you made.
After enabling guest access and configuring permissions, it might take some time (up to 24 hours) for the changes to take effect across your organization’s Teams environment.
Let’s consider a scenario where your organization needs to collaborate with external partners on a specific project using Microsoft Teams.
By following these steps, the external partners are now able to collaborate with your organization through Teams, with the configuration reflecting the ideal balance between collaboration and security.
Setting Option | Description | Recommended for Sensitive Data | Recommended for General Collaboration |
---|---|---|---|
Guest user permissions are limited | Determines if guests have limited access to data | Yes | No |
Admins and users in the guest inviter role can invite | Allows certain roles to invite guests | Yes | Yes |
Members can invite | Allows non-admin members to invite guests | No | Yes |
Guests can invite | Allows guests to invite other guests | No | No |
Enable Email One-Time Passcode for guests | Allows guests to authenticate using a code sent to their email | No | Yes |
This table can help admins decide which settings to apply based on their organization’s needs for security and ease of collaboration.
In summary, managing guest access in Microsoft Teams requires configuring settings both in the Azure AD admin center and the Teams admin center. Admins should always consider their organization’s security policies when enabling guest access and adjust the settings accordingly.
Explanation: You do not need Azure AD Premium licenses for each member in the tenant to configure guest access to Microsoft Teams. Basic guest access is included with the Azure AD subscription that comes with Office
Explanation: The ‘Allow guest access in Microsoft Teams’ setting is managed from the Azure AD admin center under the ‘External collaboration settings’, not the Microsoft Teams admin center.
Explanation: Guests can use any email address to be added to Microsoft Teams, not just a Microsoft account. This includes Gmail, Yahoo, or any other email service provider.
Explanation: Azure Active Directory is required to manage guest access and permissions in Microsoft Teams. Guests do not require their own Teams licenses, and a Microsoft 365 subscription is required for the tenant, not specifically for guest access.
Explanation: After enabling guest access in Azure AD, you also need to configure guest access settings in the Teams admin center to control what guests can do within Teams.
Explanation: PowerShell can be used to configure various settings in Microsoft Teams, including guest access settings, through the Microsoft Teams PowerShell module.
Explanation: Within the guest access settings, you can restrict what actions guests can perform, such as creating channels and accessing files. Starting new conversations is typically not a configurable option, and inviting new guests is controlled at the tenant level.
Explanation: Guest users only gain access to the teams and channels they are explicitly invited to. They do not have the same visibility or access rights as regular users by default.
Explanation: Guest access policies are set at the tenant level in Azure AD and apply to all guest users. There are no individual user-level guest access policies.
Explanation: You can configure guest permissions to prevent them from taking certain actions, like creating channels, within Teams. Guests cannot delete any message, there’s no CAPTCHA test requirement for login, and guests cannot be administrators for Microsoft Teams.
Explanation: Azure AD B2B (Business-to-Business) Collaboration is the underpinning feature that allows organizations to add guest users to Microsoft Teams. It should be enabled as part of the guest access setup.
Explanation: Guest access in Microsoft Teams does not include the ability for guests to use the tenant’s phone system to make and receive calls. Guest capabilities are limited to what is allowed through settings and do not extend to full telephony features within the tenant’s environment.
Microsoft Teams guest access allows people outside your organization to access your team’s channels and files. It’s important because it enables collaboration with partners, vendors, and customers, without requiring them to have a Microsoft account.
To enable guest access, go to the Teams admin center and select “Org-wide settings.” Then, choose “Guest access” and turn it on.
To add a guest to a channel, go to the channel’s “…” menu and select “Add members.” Then, enter the guest’s email address and click “Add.”
To remove a guest from a channel, go to the channel’s “…” menu, select “Manage members,” and then click the “x” next to the guest’s name.
A guest is someone outside your organization who has been granted access to a specific team or channel. A member is someone who is part of your organization and has access to all teams and channels.
To set guest permissions, go to the Teams admin center and select “Org-wide settings.” Then, choose “Guest access” and click “Edit” to customize permissions.
To manage guest access in Azure AD, go to the Azure portal and select “External identities.” From there, you can manage guest invitations, configure guest access settings, and view guest activity.
Azure AD B2B enables secure collaboration with external users, simplifies guest management, and provides visibility into guest activity.
To add a guest user to Azure AD, go to the Azure portal and select “External identities.” Then, click “New guest user” and follow the prompts to create the user account.
Azure RBAC (Role-Based Access Control) is a framework for managing access to Azure resources. It can be used to assign roles to external users (such as guests in Microsoft Teams) and control what they can do within a specific Azure resource.
