Display Name: User's name displayed in the email header.
Email Address: User's work email address.
Enabled: Indicates if display name anti-spoofing is turned on.
Updated At: Date and time that the display name was last updated.
Select Add to add a single display name or multiple display names. The users associated with these display names will be protected by anti-spoofing.
To add a single display name:
Select Single Display Name and enter the following details:
Display Name: User's name displayed in the email header.
Email Address: User's work email address.
Select Add.
To add multiple display names:
Select Multiple Display Name to upload a CSV file containing multiple users and their email addresses.
If you don't already have a list of users, you can go to your Microsoft Entra ID portal and export users from there. You can do so by selecting All users > Download users. Alternatively, you can go to your Group Members section, and select Bulk operations > Download members. Both options will provide a CSV file for download.
Once you have your list of users, you'll need to download the CSV template, by selecting it in Step 1, as shown below.
Save it and populate it with the display name data from the Entra ID file you downloaded. Note that the CSV template only requires Display Names and Email Addresses, so you will need to extract only this data from the Entra ID file.
Upload your new CSV file by clicking in the indicated area in the UI.
Locate the file in the pop-up window or drag and drop it from your folder.
After you've added display names, they'll appear in the display name list.
