Why does my account not allow me to change my primary alias to my gmail? normally this...

Hi. My name is Brilliant, an independent advisor, happy to assist you today.

I’m sorry to hear that you’re having trouble changing your primary alias on your Xbox account. Here is a thread with some more details on a possible solution for an issue similar to the one you're faced with: https://answers.microsoft.com/thread/9a132b36-1467-469b-bca3-74ddc4f89ed4

I hope this helps resolve your query.

Sorry if I’m causing a hassle but I just want clarification. So if I delete the account with the gmail on it and make that gmail my primary alias on my second account will that work? Greatly appreciate the help!

ok. so I've added my sons gmail account as an alias. if I make the gmail primary how does that effect the Hotmail account & how I log in to my laptops? can he log in to his xbox with the gmail (& see his gamertag & profile) & can I log in to my devices
with the Hotmail address?

I think I need to clarify. I'm trying to add my gmail as an alias so I can add it as primary. Trying to delete Yahoo as my primary login alias

Okay, I followed the directions and was able to add an alias to my account using his gmail account. There is only one problem, it had me add his gmail account as the primary and now when I send emails, it looks like it is coming from him now. I only
wanted the alias to be associated with his XBOX without affecting my microsoft account. Is there anyway around this?
