I've searched around on these forums for this question and I have found similar discussions... but I want to ask it again (on behalf of my wife).

Our ISP had recently been bought out by another company and was sun-setting our email accounts.  We both have MS accounts that were setup with these ISP based email accounts as the primary alias.  My wife misunderstood (or I gave bad instructions) on adding a new alias to this account and removing the old email address.  Instead, she created a new MS account and proceeded to update all of her various email subscriptions to this new account/alias.

Is there a way a MS person can help to move the new alias to the old account and then close out the newly created (accidental) account?  I understand that you can drop the alias, wait 30 days, add the alias to the other account, and then delete the new (accidental) account.  But, this email alias is very active and it would be incredibly inconvenient to have to create another temporary alias, switch to it, and then in 30 days switch back to the other alias.

Can someone help?  Please?  :)
