Introduction

This article explains how to invite guests to a Microsoft Teams team that has guest access disabled, using the External User Manager (EUM).

Problem Statement

In instances where a team within Microsoft Teams has the guest access option disabled, administrators might wonder if it's still possible to invite external users through the External User Manager (EUM).

Step-by-Step Solution

1. Verify Extended Trust Permission: To invite an external user to a team with guest access disabled, ensure that EUM has the 'Extended Trust' permission granted in your environment.

2. Attempt to Invite a Guest:

   • If you create a guest request in EUM for a team with guest access disabled, the request can be created.
   • However, when you try to approve this request, EUM will prevent the approval process because the team's settings do not allow guest access.

3. Error Message: EUM will display an error message or notification highlighting that the guest cannot be added to the team due to the current settings.

4. Enabling Guest Access: To allow the guest invitation, you will need to enable guest access for the specific team, or adjust the EUM settings to allow such invitations despite the team's guest access settings.

Additional Tips

• It is important to understand the implications of granting 'Extended Trust' permissions and how they interact with your existing environment and security policies.
• Regularly review your Teams' guest access settings and the EUM configuration to avoid conflicts and ensure seamless collaboration with external users.

FAQs

Q: Will granting 'Extended Trust' override the team's guest access settings? A: Yes, granting 'Extended Trust' to EUM can allow it to invite guests even if the team's settings have guest access disabled.

Q: Is it secure to grant 'Extended Trust' permission to EUM? A: Granting 'Extended Trust' permissions should be done with caution. Review your security policies and consider the implications before modifying these settings.

Q: What should I do if I cannot approve a guest invitation? A: If you cannot approve a guest invitation, check the team's guest access settings and the 'Extended Trust' permission for EUM. Adjust as necessary to align with your organization's policies and needs.

Troubleshooting Further Issues

If you encounter issues even after granting the required permissions, consider the following:

• Confirm that the team's settings and EUM configurations are aligned.
• Double-check that the 'Extended Trust' permission is correctly granted and active.
• Review the EUM logs for any specific error messages that could provide additional insight into the issue.
