+ 1 Votes You should have not changed!!!??? Mehul Bhai August 9, 2013 at 6:07am PST You should have not changed the e-mail ID. You can still continue using the Hotmail ID even though the E-mail Service has been changed to Outlook.com by Microsoft. I still use my old Hotmail ID even after converting the service to Outlook.com. It is still working. Even Microsoft claims that way. AND for trial just send a test mail from any ID you are having in any other service like, Yahoo, etc., to your old Hotmail ID, you may still receive in your new Outlook.com ID. Just you have to test it yourself. + 0 Votes I think you have misunderstood my question. Healer August 11, 2013 at 6:02pm PST I thank you for your input anyway. I understand they are all the same. After changing the email ID, I still can use it as the same live ID with the same password logging into Microsoft web sites. One important effect I got for the change was that the SPAM mail had completely stopped. I had been receiving rubbish so much I got sick of it and stopped using the account. Before I really want to start using this account I want to create aliases for actual use so that I can kill off the email address without killiing off the account once I receive too much SPAM mail. + 1 Votes I don't think you will be able to create an alias to a Yahoo account... wizard57m-cnet Moderator August 7, 2013 at 12:05pm PST maybe if that account is a "premium" account which you pay for, that also has POP3/SMTP service and not just "web based" as the free version is. I just ran through the preliminaries, didn't create an alias, and the choices on my account (which is still just a "hotmail" account) only listed the 3 primary Microsoft domains...live.com, hotmail.com and outlook.com. So, you might not be allowed to use an alias with another domain, especially if it is only web based. + 0 Votes Well, I've just double checked. Healer August 11, 2013 at 6:19pm PST And I do have aliases with one of the Yahoo accounts. All the disposable addresses have a consistently unchanged basename. All my Yahoo accounts are free accounts. If yours don't have such feature, it could be that you created the Yahoo account later than I did. I think Yahoo could have changed the policy later on.
