-
Not all versions of OneDrive for Mac can sync all folders. See below for more details.
-
No data will be lost by unlinking and re-linking your OneDrive, your local folders are just disconnected from the cloud for a short while. Any changes made while you're unlinked will be synced once re-linking is complete.

-
Click the OneDrive cloud icon up in your Menu bar, click the three dots to open the menu, and select Preferences.
-
Go to the Account tab.
-
Select Unlink this PC.

Search for “OneDrive.”
-
Delete OneDrive Cached Credential.
: The steps to delete Keychains may vary, an alternative approach is to choose Window > Keychain Access, then choose File > Delete Keychain [OneDrive/Office/MS] and click Delete References.
3. Sign in again to re-link your account
-
Use Spotlight to search for OneDrive and open it.
-
When you sign in, OneDrive will prompt you that a folder already exists: select Use this folder.
: Select Choose new folder if you want to move your OneDrive to a new location.
-
OneDrive will now sync your files and folders back to your computer. OneDrive won't download all your files, (just their placeholders to save space, learn more), but this will still take some time.

Once your files have re-synced, you can clean up your Computer folder view and choose which folders to sync to your computer.
