I am still receiving Birthday Calendar notifications from a Microsoft account that I had closed in the past 6 months.  Because the account was closed, there is no way to be able to log back into the account to check and/or change the Birthday Calendar settings.  Therefore, I decided to re-create the Microsoft account by using the same credentials including the same email address that I used with the original account.  I thought that I would somehow then be able to regain access to the original Birthday Calendar.  However, this did not work and all I succeeded in doing was creating a new and different Microsoft account, even though it uses the same email address as the closed Microsoft account.  I would like the original Birthday Calendar closed/removed permanently and the notifications stopped please.  I will await a Microsoft Support Representative's response via private message, then I will respond with the necessary information.  Thank you.
