Azure ad connect change userprincipalname to mail

A great question!

Azure AD Connect is a tool that synchronizes on-premises Active Directory with Azure Active Directory (Azure AD). By default, it maps the userPrincipalName attribute to the userPrincipalName attribute in Azure AD. However, you can configure Azure AD Connect to map the userPrincipalName attribute to the mail attribute in Azure AD.

Here are the steps to change the userPrincipalName to mail in Azure AD Connect:

Prerequisites:

  1. Make sure you have Azure AD Connect installed and configured.
  2. Ensure that you have the necessary permissions to modify the Azure AD Connect configuration.

Step 1: Open Azure AD Connect

Open the Azure AD Connect console by searching for "Azure AD Connect" in the Start menu (Windows) or Spotlight search (macOS).

Step 2: Navigate to the "Configure" tab

In the Azure AD Connect console, navigate to the "Configure" tab.

Step 3: Click on "Directory Extensions"

In the "Configure" tab, click on "Directory Extensions" in the left-hand menu.

Step 4: Find the "userPrincipalName" attribute

In the "Directory Extensions" window, scroll down and find the "userPrincipalName" attribute.

Step 5: Click on the "Edit" button

Click on the "Edit" button next to the "userPrincipalName" attribute.

Step 6: Select "Mail" as the target attribute

In the "Edit Attribute" window, select "Mail" as the target attribute.

Step 7: Click "OK" to save the changes

Click "OK" to save the changes.

Step 8: Synchronize the changes

To apply the changes, click on the "Synchronize" button in the Azure AD Connect console.

After synchronizing the changes, the userPrincipalName attribute in Azure AD will be updated to match the mail attribute in your on-premises Active Directory.
