If you're being told there is an existing account link when you attempt to link your Xbox account then it means your Xbox account is already linked to another Bungie profile. Easy way to check, sign out of Bungie.net (or open a Incognito/inPrivate/whatever your browser names it tab), sign into Bungie.net as the Xbox account and 1 of 2 things will happen: - It will tell you to sign up or link to an existing account - if it does this then just close the tab/sign in window without proceeding any further (for now) - It signs you into a different Bungie account. If it does the second thing and signs you into a Bungie account then you will be unable to link the Xbox account to the profile you posted this thread on (Lazarus_Titan) due to the March 25th 2025 linking change.
