Reserve/Forcechange a GamerTag

The Xbox system does not use the forum. To make a GT change you have to pay for it, provide no one owns the GT you like. Since the system says its taken already then you will need to come up with something new

I'm sorry, but MegaMasterX and MegaMaster X are two different tags, and I get a different message when trying to change my tag to "MegaMaster X".

I called Xbox Support back and am hoping to get some results soon. It's not like I'm trying to take a Gamertag from someone who is actively using it at all.

If it was indeed taken by someone else, wouldn't it show up in search results for Xbox Support's internal tools or on Xbox Live?

It doesn't state that it's unavailable, just that its reserved. I was informed to ask for Enforcement's aid in this by Xbox Support directly.

There is no way to reserve gamertags, as no such specific system exists. All gamertags are on a first-come, first-serve basis. If it has already been taken, you will have to choose another name.

The only way to "reserve" a gamertag is to create a new Microsoft account with that gamertag (if you plan on starting fresh), or pay the fee to change your gamertag on your existing Microsoft account.

Gamertags are released if a user does not log on to their Microsoft account for five straight years, as that is how Microsoft purges inactive accounts from their systems. Some people may not have an Xbox profile, but they still keep their Microsoft account
active through other Microsoft services (email, Office, etc). There is no way to check the remaining time (before termination) of any given account.
