Question details

Users encounter a server error message when attempting to save Delivery Management modifications for a distribution group.

Product: Exchange Admin Center (Microsoft 365)
Device & OS: not provided
Scenario: Updating Delivery Management settings to restrict or allow senders for a specific distribution group.
Observed behavior: The Exchange admin center displays the error: 'There was an issue saving your changes. We are experiencing an issue with our server. Please try submitting your request later.'

Before you start

Ensure you have the exact error message and the name of the affected distribution group handy before reaching out to your administrator or support team.

Solution 1Recommended

Open a Service Request with Microsoft Support

Because this issue often stems from directory synchronization failures or backend permissions, a Microsoft 365 global administrator needs to request a log investigation.

This specific error generally indicates a service-side failure or synchronization blockage that cannot be fixed from the user-facing Exchange Admin Center interface. Microsoft Support has the backend access required to view server logs and clear the synchronization error.

Log into the Admin Center

Have a Microsoft 365 global administrator log in to the Microsoft 365 Admin Center.

Navigate to Support

Click on 'Support' and then select 'New service request' from the left-hand navigation menu.

Submit Issue Details

Describe the delivery management error, provide the affected distribution group's name, and request that support investigate the configuration and relevant backend logs.

Administrator Privileges Required: Only users with global administrator rights can open a support ticket directly with Microsoft 365.

Solution 2

Escalate Through Your Cloud Reseller

If your organization's Microsoft 365 subscription is managed by a third-party reseller, support requests must be routed through them.
