Change assigned e-mail to O365 based one

thanks, so there is no way to use my phrchased o365 subscription/azuread use onxbox? that's more than pathetic.

so why? and how it can be fixed if i want to change my existing address? there is no point to create a new n+1 outlook.ie address.

it so stupid

Hi Kev,

Thanks, I tried that one at the first place and get the error message "You can't add a work or school email address as an alias to a personal Microsoft account. Please try another."

also, when i tried to add my never used outlook.ie account (which is working but really don't want to use it as an alias) i received the bit strange error message "This email address is already taken. Please try another."

The problem is that you cannot use an existing, work or school MS mail account as an alias for another account. I'll link the general office support page (it applies to anything related to MS accounts anyway) with more details about alias options and such
limitations listed:

Specifically these two points are the reason why both things you tried are failing:

- You can't add an email address that's associated with a work or school account as an alias.

- Existing Hotmail, Live, Outlook.com, and MSN addresses can't be added as aliases, and you can't add an alias that is already associated with another Microsoft account.

Good news everybody! I finally managed to change the e-mail associated with my gamertag! I will describe how it was done.

My problem:

I had one original gamertag that was used on my xbox and had achievements and purchases assigned to it. The e-mail address however was old and not in use. Then, due to Windows 8 and a random sign in to xbox.com, I had a 2nd gamertag, this one had nothing
assigned to it, BUT it was assigned to my preferred, primary, e-mail account. Googling this issue led me nowhere, solutions I saw was "make a 3rd e-mail account, move gamertag to that, them move to the first etc."

Solution:

This solution is based on changing whats regarded as the primary alias to your Microsoft ID. Your MS ID is also whats used for xbox.com and the xbox.

1. Log into https://account.live.com/. Look at overview. Here, add a primary alias. Create a new at @outlook.com address. Note that this will be the login for this account in the future!

2. After you have added the alias, make that alias primary.

3. Then, remove the old e-mail you want freed. The e-mail address you want to use on the other Microsoft ID.

Then, we move on to the MS ID you want to use. In my case, this MS ID was associated to an old expired e-mail account.

1. Log into https://account.live.com/. Look at overview. Here, add a primary alias. Use the e-mail you freed on the other account.

2. After you have added the alias, make that alias primary.

3. Remove the expired old e-mail address.
