Question details

The user needs to ensure that all members of a dynamic Microsoft 365 group receive emails sent to the group address.

How to Email Members of a Dynamic Microsoft 365 Group

Product: Microsoft 365 Exchange Online
Device & OS: not provided
Scenario: Administrators want to send emails to dynamic group members who are not automatically receiving group conversations in their inboxes.
Observed behavior: Members of a dynamic group do not automatically receive group emails because they are added as members but not as active subscribers to the group's conversations.

Before you start

Ensure you have the Exchange Online PowerShell module installed and possess the required administrator permissions to execute commands on your Microsoft 365 tenant.

Solution 1Recommended

Subscribe Members via Exchange Online PowerShell

Use a PowerShell script to automatically fetch all current dynamic group members and add them to the group's subscriber list.

By default, dynamic Microsoft 365 group members might not be subscribed to receive emails in their personal inbox. You can force this subscription using Exchange Online PowerShell.

Connect to Exchange Online

Open PowerShell on your device and connect to Exchange Online using your administrator credentials.

Run the Add-UnifiedGroupLinks script

Run the following command to fetch current members and pipe it to Add-UnifiedGroupLinks. Replace 'group@domain.com' with your actual group email address: Get-UnifiedGroupLinks group@domain.com -LinkType Members | ForEach-Object { Add-UnifiedGroupLinks group@domain.com -LinkType Subscribers -Links $_.PrimarySmtpAddress }

Verify member SMTP addresses

Confirm that each returned member has a valid PrimarySmtpAddress. If the script throws errors for specific members, check their account details in the admin center to ensure their email addresses are not blank.

SMTP Address Requirement: Blank primary SMTP addresses will prevent the subscriber update from working for those specific users. Ensure all dynamic group members have a properly configured email address.

Frequently Asked Questions

Why aren't my dynamic Microsoft 365 group members receiving emails?

In Microsoft 365, being a member of a dynamic group does not automatically subscribe the user to receive the group's email conversations in their personal inbox. They must be added as active subscribers by an administrator.

What happens if a group member has a blank Primary SMTP address?

If a member lacks a valid Primary SMTP address, the PowerShell command to add them as a subscriber will fail for that specific user. You must ensure all members have valid email addresses assigned in Exchange.

Do I need administrator privileges to run these PowerShell commands?

Yes, you need the appropriate Exchange Online administrator roles to connect to the Exchange Online PowerShell module and modify unified group subscription settings.
