Teams email distribution list in Outlook

Good day Stefny, 

Thank you for sharing your concern.  

In most cases, a Microsoft Team is backed by a Microsoft 365 Group. If the associated Microsoft 365 Group is hidden from Outlook or has not completed synchronization, the Team's email address may not appear in Outlook Contacts or the Global address list. 

If you are an end user, please contact your organization's IT administrator and ask them to perform the steps below: 

Note: In case you do not know who is your IT admin, kindly refer to this article: How do I find my Microsoft 365 admin? - Microsoft Support  

Option 1: Ask your IT admin to make the Team visible in Outlook 

Confirm that you're a member of the Microsoft 365 Group associated with the Team. 

The administrator can verify this in the Exchange admin center by navigating to Recipients > Groups, selecting the group and reviewing the Members tab. 

If you aren't listed as a member, the administrator should add you to the group. 

The administrator should then verify whether the Microsoft 365 Group is hidden from Outlook clients. 

In Exchange Online PowerShell, the admin can check: 

Get-UnifiedGroup -Identity <group name> | FL HiddenFromExchangeClientsEnabled  

If the value is True, the admin can make the group visible in Outlook by running: 

Set-UnifiedGroup -Identity <group name> -HiddenFromExchangeClientsEnabled:$false  

After the change is applied, allow time for Outlook to update. 

If you're using Classic Outlook: 

Please go to File > Account Settings > Account Settings. 

Double-click your email account. 

Make sure that Cached Exchange Mode is enabled.

Option 2: Contact Microsoft Support 

If the issue persists after completing the steps above, I recommend that your IT administrator create a support ticket through the Microsoft 365 Admin Center > Support > Help & Support for further backend investigation.  

A technical support engineer can perform a remote session to investigate the situation, verify the backend configurations, and run any necessary synchronization tools to resolve the problem. If the issue requires further attention, they can escalate it to a specialized team for deeper analysis.    

I hope this information is helpful. If you have any questions or need further support, please don’t hesitate to reach out at any time. 

Thank you for your patience and understanding.
