How to Fix Cannot Edit the EVERYBODY Dynamic Distribution List Error
Question details
The user is unable to modify the EVERYBODY dynamic distribution list and encounters a group update error.

- Product
- Microsoft 365 Exchange Online
- Device & OS
- not provided
- Scenario
- Attempting to edit the properties or membership rules of the EVERYBODY dynamic distribution list within Microsoft 365.
- Observed behavior
- The system prevents the modification and displays the error message: 'We couldn't update this group. Please try again.'
Ensure you are logged in with Global Administrator or Exchange Administrator credentials and have access to Exchange Online PowerShell.
Check Active Directory Synchronization Status via PowerShell
Determine if the dynamic distribution list is managed by an on-premises Active Directory, which blocks direct cloud edits.
When an object like a dynamic distribution group is synced from an on-premises Active Directory environment using Azure AD Connect, it cannot be modified directly in the Microsoft 365 Admin Center. All structural changes must be made locally and synced to the cloud.
Open PowerShell as an administrator and connect to Exchange Online using your Global Admin credentials.
Execute the cmdlet 'Get-DynamicDistributionGroup -Identity "EVERYBODY"' to pull the configuration details for the affected list.
Review the output properties to verify if the group is synchronized from your on-premises Active Directory environment.
If the group is synced from on-premises AD, log into your local Active Directory server, make the necessary edits to the distribution list there, and wait for the next directory synchronization cycle to update Microsoft 365.

Open a Microsoft 365 Support Request
If the group is cloud-only and the error persists, escalate the issue to Microsoft Support for backend log analysis.

Frequently Asked Questions
Why do I get 'We couldn't update this group' when editing a dynamic distribution list?
This error most commonly occurs when the dynamic distribution list is synchronized from an on-premises Active Directory. Microsoft 365 locks these synced objects to prevent conflicting configurations between the cloud and the local server.
How can I verify if my dynamic distribution list is synced from on-premises AD?
You can verify this by running the 'Get-DynamicDistributionGroup' cmdlet in Exchange Online PowerShell and checking the group's properties, or by looking for the 'DirSyncEnabled' status in the Microsoft 365 Admin Center.
Can I edit an on-premises synced distribution group directly in the Microsoft 365 Admin Center?
No. If a group is synchronized from your local Active Directory, you must make all changes in your on-premises AD environment. Those changes will automatically push to Microsoft 365 during the next Azure AD Connect sync cycle.
What if my subscription is managed by a reseller?
If your Microsoft 365 licenses and services are managed by a Cloud Solution Provider (CSP) or reseller, you will need to contact them directly to open a backend diagnostic support ticket on your behalf.
