As the case shows, many users wonder "Can I merge two OneDrive accounts" or "how to combine two OneDrive accounts" nowadays, actually, of course, you can. As long as you find a good method, you can merge two or multiple OneDrive accounts into one, and manage everything in one OneDrive account.

If you have more than one OneDrive accounts and don't know how to merge two OneDrive accounts into one, you can keep reading to learn two effective ways to merge all your OneDrive accounts with a third-party cloud backup service - CBackup or OneDrive in-built feature.

Way 1. Merge OneDrive accounts via CBackup (Easiest)

The easiest way to merge OneDrive accounts must be using a third-party tool, which can help you merge and run multiple OneDrive accounts on one PC with one login.

Way 2. Merge OneDrive accounts via “Sharing” feature (Manually)

OneDrive “Sharing” feature can help you connect OneDrive accounts by creating a shared folder and sharing it with other accounts. In this way, you can choose a primary account and share files in other accounts with this account. After sharing, you can see all of your files in only one account without the need of switching accounts. To achieve that, do the following:

1. Go to the OneDrive website and sign in with your Microsoft account.

2. Click on the “+ New” button to create a new folder and name it “Shared Folder” and move all your files in this account to “Shared Folder”.
