Hello,
Since an official "Merge" button doesn't exist, here is how you can functionally consolidate your digital footprint without losing your history:
- Log into your Xbox with Account A > Go to Settings > General > Personalization > My home Xbox > Select Make this my home Xbox > Now, any other account (Account B) on that console can play Account A’s games and use its Game Pass subscription
- Use Alias Option: You cannot merge two existing @outlook.com or @hotmail.com accounts
// Pick your "Primary" account //
Go to Account Settings > Your Info > Edit account info > Add an Alias using a third-party email (Gmail, iCloud) or a new Outlook address
"Note: You cannot add an existing Microsoft account as an alias to another." - For files: Manual Migration: Use a PC to sync both OneDrive accounts > Simply drag and drop the folders > Wait for the sync
Final Thought: The industry is moving toward "Family Sharing" as the workaround, allowing multiple IDs to share a single "pool" of purchases without actually merging the identities
I hope this helps.
Regards,
