Tutorial / Cram Notes
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.
Configuring Guest Access to Microsoft Teams
Here’s how to configure guest access to Microsoft Teams using the Azure AD admin center:
- Open the Azure AD Admin Center
Navigate to https://aad.portal.azure.com and sign in using an account with admin permissions.
- Select External Identities
On the left-hand navigation pane, click on “External Identities” to manage the settings for external users in Azure AD.
- Manage External Collaboration Settings
Within the External Identities section, select “External collaboration settings”. Here, you can manage how guests can interact with your organization.
- Configure Guest Settings
In the external collaboration settings, configure the settings that affect guest user permissions. For example:
- Guest user permissions are limited: If Yes, guests do not have the same access to data as members.
- Admins and users in the guest inviter role can invite: If Yes, they can invite guests.
- Members can invite: If Yes, this allows non-admin users to invite guests.
- Guests can invite: If Yes, existing guests can invite new guests (not generally recommended).
- Enable Email One-Time Passcode for guests (Preview): If Yes, guests without a Microsoft account can sign in with a one-time passcode sent to their email.
Ensure to tailor these settings in line with what is suitable for your organization.
- Enable Guest Access in Teams
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.
- Configure Guest Access Permissions
Below the main setting to “Allow guest access in Teams,” you can configure what guests are allowed to do within Teams, including:
- Making private calls
- Meeting experiences
- Messaging
- Using apps in Teams and more.
- Save Your Changes
After configuring your settings, ensure to click on “Save” to apply the policy changes you made.
- Wait for Replication
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.
Example Scenario:
Let’s consider a scenario where your organization needs to collaborate with external partners on a specific project using Microsoft Teams.
- You make sure that “Guest user permissions are limited” is set to Yes to safeguard your organization’s data.
- You enable “Admins and users in the guest inviter role can invite” and “Members can invite” to ensure that the project team can invite the external partners as guests.
- You do not enable “Guests can invite” to prevent unvetted access.
- You ensure that the email one-time passcode feature is enabled for those without a Microsoft account to facilitate hassle-free collaboration.
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.
Comparative Table of Guest Access Settings:
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.
