getMail() method is returning the email alias instead of real email address

Describe the bug

I'm using the SDK in order to allow the user to get authenticated on my platform.

The problem that I'm facing is that the getMail() is returning the email alias instead of the real email. For example:

• user get authenticated using the account danielrealuser@gmail.com;
• the user get authenticated, however, the real email address is randomvalue@outlook.com;
• instead or returning randomvalue@outlook.com it returns danielrealuser@gmail.com.

Expected behavior

When requesting the data regarding the user, it should return the real user email in the property getMail, however, it gets the alias used to authenticate on Outlook.

How to reproduce

These are the scopes that I'm using (and I'll user more later not related to this topic):
"email",
"Mail.Read",
"Mail.Read.Shared",
"Mail.ReadBasic",
"Mail.ReadBasic.Shared",
"offline_access",
"openid",
"profile",
"User.Read.all",
"User.ReadBasic.All",
"ExternalUserProfile.Read.All"

Code implementation

    public User getUserProfile(String accessToken) {
        GraphServiceClient graphClient = createGraphServiceClient(accessToken);
        return graphClient.me().get();
    }

            IAuthenticationResult authResult = this.exchangeCodeForTokens(authCode);
            User user = this.getUserProfile(authResult.accessToken());

            // Get user profile using the access token
            return new MicrosoftUserData(
                    user.getId(),
                    user.getGivenName(),
                    user.getSurname(),
                    user.getMail(),
                    authResult.accessToken(),
                    authResult.accessToken(), // Use refresh token instead of access token twice
                    user.getDisplayName(),
                    getProfilePictureDataUrl(authResult.accessToken())
            );

### Other information

_No response_

Start with getUserProfile and the graphClient.me().get() call, then inspect how User.getMail() maps the Microsoft Graph profile response. Compare the reported alias and real address behavior with the listed scopes and current SDK behavior. Done means the profile lookup returns the expected address or clearly documents the API limitation, with a regression test if the SDK controls the mapping.
