How to Change or Rename a SharePoint Group Email Address

Maira Mehtab Sep 27, 2026 869 views

Question details

The user needs to change or rename the email address associated with a SharePoint group, typically because a numerical suffix was automatically added when the preferred name was already in use.

Product: Microsoft SharePoint
Device & OS: not provided
Scenario: Modifying group email settings in the admin center to ensure the SharePoint site uses the correct preferred email address.
Observed behavior: The SharePoint site name and the Microsoft 365 group address are managed separately, resulting in the group receiving an email address with unwanted numerical suffixes.

Before you start

Ensure you have Global Administrator or Exchange Administrator privileges in Microsoft 365 before attempting to modify group email addresses.

Solution 1Recommended

Change Primary Email Address via Microsoft 365 Admin Center

Use the Microsoft 365 Admin Center to directly edit the group's email settings, allowing you to set a new primary address or add aliases.

Since site names and Microsoft 365 group addresses are managed independently, updating the SharePoint site name will not automatically fix the email address. You must manually adjust this in the Admin Center.

Open the Microsoft 365 Admin Center

Log in to your Microsoft 365 account using credentials that have Global Administrator permissions, and navigate to the Admin Center dashboard.

Navigate to Active Groups

On the left-hand navigation pane, click on 'Groups' to expand the menu, and then select 'Active groups'.

Locate the Specific Site Address

Scroll through the list or use the search bar to find the Microsoft 365 group associated with your SharePoint site.

Edit Email Addresses

Select the group to open its details panel, click on the menu (often represented by three dots or directly visible under settings), and choose 'Edit email addresses'.

Update the Primary Address

Type in your preferred email address to replace the existing one (removing any numerical suffixes) and set it as the primary address, or add it as an available alias, then save your changes.

Name Availability: The new email address you wish to assign must not be currently in use by another user, group, or resource in your Microsoft 365 environment.

Frequently Asked Questions

Why did my SharePoint group get a number added to its email address?

When creating a SharePoint site, if the corresponding group email name is already in use by another user, shared mailbox, or group, Microsoft 365 automatically appends a numerical suffix to ensure the new address remains unique.

Can a standard user change the SharePoint group email address?

No, changing a Microsoft 365 group email address requires administrative permissions. You must be a Global Administrator or Exchange Administrator to access the required settings in the Microsoft 365 admin center.

Does renaming the SharePoint site automatically change its email address?

No, SharePoint site names and their associated Microsoft 365 group email addresses are managed separately. Renaming the site via SharePoint settings will not automatically update the underlying group email address.

Will changing the group email address affect the SharePoint site URL?

No, modifying the group's email address only affects email delivery and group identification in Outlook and Teams. It does not alter your existing SharePoint site's URL.
