Tutorial / Cram Notes
External access is different from guest access as it allows for inter-domain communication rather than adding an external user as a guest to a team. Federated domains can find, call, chat, and set up meetings with users in other domains. For this communication to happen, both parties must allow external access to their respective domains.
Configuring External Access
Here are the steps to configure external access in Microsoft Teams:
- Open the Microsoft Teams admin center.
- Navigate to the ‘Org-wide settings’ tab, then select ‘External access’.
- Use the toggle to turn on or off the external access. Turning it on will allow users to communicate with external domains.
- You can choose to:
- Allow any domain (open federation), or
- Allow specific domains by adding them to the ‘Allowed domains’ list, or
- Block certain domains by adding them to the ‘Blocked domains’ list.
Managing External Access with PowerShell
Administrators can also manage external access using PowerShell. The Set-CsTenantFederationConfiguration cmdlet allows for configuring federation settings, such as enabling or disabling it, and specifying allowed or blocked domains.
Determining When to Use External Access
Deciding whether to use external access depends on business needs. For example, if an organization frequently collaborates with certain partners, it would be beneficial to enable external access for those domains. However, for ad-hoc collaboration, one may consider using guest access instead.
Example Usage Scenario
Company A (companya.com) and Company B (companyb.com) collaborate on a project. They need to communicate regularly but maintain separate Teams environments. The Teams administrator in each company would configure the external access settings to allow their staff to communicate with the other company’s domain.
Security and Compliance Considerations
When configuring external access, it’s important to balance collaboration needs with security and compliance requirements. Companies must ensure that external communications do not compromise sensitive information or violate any data protection regulations.
Monitoring and Reporting
Monitoring external connections is critical. Administrators must regularly examine the external access usage reports available in the Teams admin center to oversee who is communicating with who from the outside organization, and ensure compliance with company policies.
Benefits and Limitations
| Benefits | Limitations |
|---|---|
| Improved collaboration | Potential data leakage if not monitored |
| Seamless communication between firms | Certain features may not be available |
| Reduces the need for guest accounts | Requires both parties to enable federation |
| No need for multiple user accounts | Compliance implications must be considered |
In conclusion
managing external access and federated domains is a crucial aspect of administering Microsoft Teams. It allows for enhanced collaboration with external entities while necessitating a careful approach to security and compliance. The MS-700 exam examines a candidate’s understandings and abilities to configure and govern these features in a manner that facilitates effective communication without compromising the organization’s integrity.
Practice Test with Explanation
Federated domains require an external access policy to be configured in Microsoft Teams.
- (A) True
- (B) False
Answer: A) True
Explanation: External access in Microsoft Teams allows users to find, call, chat, and set up meetings with users in other domains. A policy must be configured to allow or restrict federations with other domains.
By default, external access in Microsoft Teams is enabled for all domains.
- (A) True
- (B) False
Answer: B) False
Explanation: By default, external access is configured in Teams to allow federation with all domains. However, administrators can restrict or block certain domains according to their organization’s needs.
When managing federated domains, which of the following options are available in Microsoft Teams admin center?
- (A) Block specific domains
- (B) Allow all domains
- (C) Allow specific domains
- (D) Disallow all domains
- (E) Manage user-level external access policies
Answer: A) Block specific domains, B) Allow all domains, C) Allow specific domains, D) Disallow all domains, E) Manage user-level external access policies
Explanation: In the Microsoft Teams admin center, administrators can block specific domains, allow all domains, allow specific domains, disallow all domains entirely, and manage user-level external access policies.
External access and guest access in Teams serve the same purpose.
- (A) True
- (B) False
Answer: B) False
Explanation: External access (federation) lets Teams users from other domains find, call, chat, and set up meetings with you. Guest access gives access permissions to an individual to join as a guest in Teams, with capabilities such as participating in chats and meetings.
To change external access settings in Microsoft Teams, you must be assigned the Global Administrator or Teams Service Administrator role.
- (A) True
- (B) False
Answer: A) True
Explanation: To change external access settings in Microsoft Teams, you need to be assigned to a role that has the necessary permissions, such as the Global Administrator or Teams Service Administrator role.
An organization can decide to allow external access only for certain users or groups within the company.
- (A) True
- (B) False
Answer: A) True
Explanation: Teams administrators can configure external access on a per-user basis by assigning policies to particular users or groups.
Which PowerShell cmdlet is used to view a list of allowed or blocked domains in external access for Microsoft Teams?
- (A) Get-CsTenantFederationConfiguration
- (B) Get-CsExternalAccessPolicy
- (C) Get-CsExternalUserCommunicationPolicy
Answer: A) Get-CsTenantFederationConfiguration
Explanation: The Get-CsTenantFederationConfiguration cmdlet is used to view the configuration information for the federation settings, including the list of allowed or blocked domains.
Once you block a domain in Microsoft Teams, users from that domain cannot be added as guests to a team.
- (A) True
- (B) False
Answer: B) False
Explanation: Blocking a domain via external access affects federation and communication capabilities but does not impact the ability to add users from that domain as guests to a team, which is controlled by guest access policies.
External access must be turned on for users in your organization to communicate with users in another Teams organization.
- (A) True
- (B) False
Answer: A) True
Explanation: External access must be enabled for your users to find and communicate with users in other Teams organizations that are not part of your tenant.
Turning on external access in Teams will also configure email integration automatically.
- (A) True
- (B) False
Answer: B) False
Explanation: Enabling external access in Teams is separate from email integration. Teams external access is specifically for communication with other Teams users, while email integration might involve settings with Exchange Online or other email services.
SIP domains can be federated in Microsoft Teams to allow communication with users from those domains.
- (A) True
- (B) False
Answer: A) True
Explanation: Session Initiation Protocol (SIP) domains can be federated in Microsoft Teams, enabling users in your organization to communicate with users in those external domains.
If a federated domain is not explicitly allowed in the Microsoft Teams admin center, users from that domain cannot communicate with your users, even if “Allow all domains” is enabled.
- (A) True
- (B) False
Answer: B) False
Explanation: “Allow all domains” overrides any not explicitly allowed domains. If “Allow all domains” is enabled, then any domain not in the blocked list can communicate with your organization’s users.
