given two onedrive accounts somehow!!

Microsoft OneDrive personal accounts and Microsoft 365 work or school accounts cannot be merged. Microsoft personal accounts also cannot be linked, merged, or combined. The supported option is to use the accounts side by side.

For OneDrive, the practical approach is:

1. Add both accounts to the OneDrive sync app.
   • On Windows, select the OneDrive cloud icon in the notification area.
   • Select the OneDrive Help and Settings icon, then Settings.
   • Open the Account tab.
   • Select Add an account.
   • Sign in with the other account.
2. Keep the storage separate.
   • The accounts remain separate.
   • Work or school folders cannot be synced or shared into personal OneDrive folders.
   • Files can be copied or dragged and dropped from one account to the other.
3. If the goal is to stop problems from using two accounts, choose one account to keep using for files and manually copy the files needed from the other account.
4. Note that only one personal OneDrive account can be added in the OneDrive app.

If the issue is a sign-in or sync problem rather than account setup, use Contact Microsoft Support for personal accounts. For work or school accounts, contact the organization’s IT helpdesk or admin.
