Hi Brown,
Thank you for sharing the details of your situation.
The message “The classification options for the group have changed. Please choose the appropriate classification” generally indicates that the classification currently assigned to the Microsoft 365 group connected to the SharePoint site is no longer available or does not match the classification options currently configured by your organization.
As a result, SharePoint may prevent the site name from being changed until the connected Microsoft 365 group has a valid classification. Since site classification is configured at the Microsoft 365 group and tenant level, please reach out to your organization’s IT administrator for further assistance.
You may share the following steps with your administrator:
- Sign in to the Microsoft 365 admin center.
- Go to Teams & groups > Active teams & groups, then locate the Microsoft 365 group connected to the affected SharePoint site.
- Copy the group’s Object ID from the group details or from its Overview page in the Microsoft Entra admin center.
- Open PowerShell. If Microsoft Graph PowerShell is not already installed, run:
Install-Module Microsoft.Graph -Scope CurrentUser - Connect to Microsoft Graph:
Connect-MgGraph -Scopes "Group.ReadWrite.All","Directory.Read.All" - Check the group’s current classification:
Get-MgGroup -GroupId "<GroupObjectID>" -Property "DisplayName,Classification" | Format-List DisplayName,Classification - If the current classification is no longer valid, update it using one of the classification values currently configured for the organization:
Update-MgGroup -GroupId "<GroupObjectID>" -Classification "<ValidClassification>"
Allow some time for the change to synchronize. Then return to the SharePoint site, go to Settings > Site information, and try changing the site name again.
The value entered for <ValidClassification> must exactly match one of the classification values currently permitted by the organization.
