Hey guys,
I just read somewhere that if you delete the account within 10 days after the registration, that the account name will be available again after 10 days.
Still need to wait about 8 days to confirm this.
But I believe this works, because I created an account once for my mom, but logged in again after a week or 2 and it said that the account didn't exist anymore. I then re-registered the same address without issues (so the account name was freed again).
I certainly hope this is true, 10 days waiting is not as bad as 270 days :-)
Best regards.
I think that only works when you have signed up for an account and haven't signed in for the first time within 10 days, the account will be deleted. So if you already signed in once, it doesn't work.
I think when an alias is deleted, then that name will become available after 30 days.
You could rename your new @outlook.com account so that your desired email becomes an alias and delete it.
I don't know if it actually works, but if it does, it still beats the 270 days of waiting:P
