title: AAD: Not receiving password expiration notification
body: <p>I've set up the notification in AAD cmdlet and also the office portal, referencing <a href="https://support.office.com/en-us/article/Set-the-password-expiration-policy-for-your-organization-0f54736f-eb22-414c-8273-498a0918678f?ui=en-US&amp;rs=en-US&amp;ad=US" rel="nofollow noreferrer">here</a>, for my AAD tenant, but no email notification was sent when account password is about to expire. I tried setting a valid email address for both "Email" and "Alternate Email" properties in account profile on AAD.</p>
