OneDrive for Mac: “You’re Already Syncing This Account”

If OneDrive for Mac says “You’re already syncing this account,” the account is already connected to the OneDrive app on that Mac, so adding it again is unnecessary. Open the existing OneDrive folder or its settings; if syncing appears stuck or you meant to add a different account, check which account is signed in before changing anything.

What the message means

OneDrive for Mac links a signed-in Microsoft account to a local folder that it keeps in sync with that account’s cloud files. The warning generally means the app recognizes that the same account is already set up. It is not, by itself, evidence that files are missing, that the account is blocked, or that you need to create a second copy of the sync setup.

There are two things people often mean when they see the message: they may be trying to open their existing OneDrive, or they may be trying to add another account. Those are different tasks. A personal Microsoft account and a work or school account can be managed differently, and organizational policies may also affect which accounts or folders can be synced.

Find the existing OneDrive folder

First look for OneDrive in the Mac menu bar. Select its cloud icon to see sync status and access settings or the folder, where available. You can also open Finder and check the sidebar or your user folder for a OneDrive location. The folder’s name can vary, especially if more than one account or organization has been used.

To confirm which account the app is using, open OneDrive’s settings or preferences from its menu-bar icon and inspect the account information. Check the email address and, for a work or school account, the organization shown. Do not assume that a folder with “OneDrive” in its name belongs to the account you currently intend to use.

• If the account is correct and the files are present, open that folder rather than adding the account again.
• If the account is correct but files are not updating, inspect the app’s sync status and follow the troubleshooting steps below.
• If the account is different from the one you want, use the account controls to add or switch accounts rather than deleting folders manually.

Add a different account

OneDrive for Mac can support personal and work or school accounts, subject to the app’s current behavior and any organization rules. The warning may appear if you try to add an account that is already connected, even when you intended to add a second account. Verify the address carefully: two accounts can have similar names, and a work account can use an email address that looks like a personal one.

Open OneDrive settings from the menu-bar cloud icon and look for the account section. If the account you want is not listed, use the option to add an account and sign in with the correct credentials. Follow the prompts to choose or confirm a local folder. If your organization manages the Mac or restricts syncing, contact its IT support rather than trying to work around those controls.

Before removing an account, read the app’s prompts and make sure any locally changed files have finished syncing or are safely copied elsewhere. Removing an account from the app is not the same thing as deleting the online account, but local folders and unsynced changes require care. Avoid deleting a OneDrive folder from Finder as a first troubleshooting step.

Check whether syncing is actually working

A connected account does not guarantee that every file is currently up to date. Select the OneDrive cloud icon and read the status or any listed problem. A paused sync, a sign-in prompt, a network interruption, insufficient disk space, or a file that cannot be synced can all prevent updates without changing the fact that the account is already connected.

1. Confirm the Mac has an internet connection and that OneDrive is not paused.
2. Check that you are signed in to the intended account and complete any sign-in request shown by the app.
3. Look for a specific file or folder error in the OneDrive status panel. Resolve the stated issue, such as a naming or access problem, rather than repeatedly adding the account.
4. Allow time for pending changes to upload or download. Large files and many small files can take longer, depending on the connection and the amount of work queued.
5. If the status does not improve, quit and reopen OneDrive or restart the Mac, then check the status again. Use the current OneDrive help or your organization’s support if the app continues to report an error.

Also compare the local folder with OneDrive on the web, using the same account. This can help distinguish a local sync issue from a sign-in mistake or a file that was never uploaded. Be cautious when resolving apparent duplicates: a file with a similar name is not necessarily the same file, and deleting one may remove the only copy of changes.

Why the message can recur

The notice may recur if you start setup from a sign-in screen while the account is already configured, if OneDrive has retained an existing account connection, or if you are selecting the wrong account during setup. On a shared or previously used Mac, another person’s OneDrive folder may also remain on disk. The folder’s presence alone does not establish that the current user is signed in to that account.

Keep macOS and OneDrive reasonably current, and make sure you are using the app for the Mac user account you intend to use. If the same account appears in settings but the app repeatedly asks you to add it, record the exact message and note whether the account is personal or managed by an organization. Those details help support staff identify whether the issue is app setup, authentication, or an organization policy.

Frequently Asked Questions

Does “You’re already syncing this account” mean my files are backed up?
No. It indicates that the account is already connected to OneDrive, not that every file has uploaded successfully. Check the app’s sync status and confirm important files are visible in the cloud account.

Where is the OneDrive folder on my Mac?
Look in Finder’s sidebar, your user folder, or the folder location shown in OneDrive’s settings. The exact name and location can differ by account and setup.

Can I use personal and work OneDrive accounts on one Mac?
The app supports account connections for personal and work or school use, but available options can depend on the current app and organization policies. Check the account section in OneDrive settings.

Will removing OneDrive delete my online files?
Removing an account from the app is not the same as deleting the Microsoft account or its cloud files. However, unsynced local changes may not be online, so check sync status and preserve needed files before disconnecting.

What should I do if the message appears but OneDrive is not syncing?
Verify the account, network connection, pause status, and any file-specific errors in the OneDrive menu-bar panel. Compare with the same account online, then restart the app or seek support if the error persists.
