How to Fix SharePoint Guest User Sync Problems on Mac
Question details
The user is unable to sync a guest institution's SharePoint document library to their Mac, preventing them from accessing shared files locally through Finder.
- Product
- SharePoint, OneDrive
- Device & OS
- macOS
- Scenario
- Attempting to sync an external guest institution's SharePoint document library using the OneDrive desktop client on a Mac.
- Observed behavior
- OneDrive displays a 'You do not have permission to sync this library' error. Clicking 'View Online' redirects the user incorrectly to their home institution's SharePoint instead of the guest institution's environment.
Ensure you have the exact guest account login credentials provided by the hosting organization, and confirm with their IT department that external guest sync permissions are explicitly enabled for your account.
Verify OneDrive Account and Guest Permissions
Ensure that the OneDrive client is actively signed in with the guest account credentials rather than defaulting to your primary organization's account.
Authentication conflicts frequently occur when a Mac is already syncing a primary work or school account. OneDrive must authenticate using the specific guest credentials granted by the external organization to establish a valid sync connection.
Click the OneDrive cloud icon in the top Mac menu bar, then click the gear icon and select 'Preferences' or 'Settings'.
Navigate to the 'Account' tab to view all currently linked accounts.
If the guest account is missing, click 'Add an Account' and sign in using the guest credentials provided by the external institution.
Reset the OneDrive App on macOS
Resetting the OneDrive application clears cached credentials and background configurations that might be incorrectly redirecting your sync requests.
Initiate Sync Directly from Microsoft Teams
Bypass browser credential caching by using the Microsoft Teams application to navigate to the guest institution's files and trigger the sync.

Frequently Asked Questions
Why does OneDrive redirect me to my home institution's SharePoint when viewing online?
This happens because your default web browser or the OneDrive client has cached the authentication tokens for your primary work/school account. To bypass this, try opening the SharePoint link in an incognito or private browsing window, or clear your browser's cache and cookies.
Can I sync multiple SharePoint accounts on the same Mac?
Yes, the OneDrive app for macOS allows you to add and sync multiple work or school accounts simultaneously. However, each account must be added individually in the OneDrive Settings under the 'Account' tab.
What does the 'You do not have permission to sync this library' error mean?
This error generally means either you are authenticated with the wrong account, or the SharePoint administrator for the guest institution has explicitly disabled the 'Offline Client Availability' setting, which prevents external guests from syncing files to their local devices.
