How to Fix Cannot Sync a Shared OneDrive Folder Between Organizations
Question details
Users are unable to sync a shared OneDrive folder from another organization because the Sync button is unavailable.
- Product
- Microsoft OneDrive
- Device & OS
- not provided
- Scenario
- Collaborating on shared Word and Excel files across different Microsoft 365 organizational (work or school) accounts.
- Observed behavior
- The shared folder can be viewed in a web browser, but it cannot be added to OneDrive or opened in desktop applications because the Sync option does not appear.
Ensure you have the contact information for your organization's IT department or Microsoft 365 administrator, as resolving cross-organizational sync issues requires administrative access to the host organization's directory.
Configure the External User as a Guest in the Host Organization
The Sync button for shared OneDrive folders across organizations requires the recipient to be officially registered as a guest user in the host's directory.
In Microsoft 365, B2B collaboration requires external users to have guest profiles within the hosting organization's Azure Active Directory. Without this, collaboration is restricted to the browser, and desktop sync features are disabled.
Reach out to the IT administrator of the organization that owns the shared folder and ask them to verify if you are listed as a guest user.
If you are not listed, ask the administrator to add your organizational email address as a guest. If you are already listed but still cannot sync, ask them to remove and reinvite you.
Once you receive the guest invitation email, open an InPrivate (Edge) or Incognito (Chrome) browser window to accept it. This prevents account conflicts.
After accepting the invitation, navigate back to the shared folder. The 'Sync' button should now be visible on the top menu bar.
Review the Organization's External Sharing Policies
If multiple external users from different organizations are experiencing this issue, the host's overarching sharing policies may be overly restrictive.

Frequently Asked Questions
Why can I view a shared OneDrive folder in the browser but not sync it?
The Sync button is typically hidden if you are accessing a shared folder from another Microsoft 365 organization and have not been officially added as a registered guest user in their directory.
Does this OneDrive syncing issue affect personal Microsoft accounts?
No, this specific restriction applies to organizational (work or school) accounts in Microsoft 365. Personal accounts generally do not require complex guest directory setups to utilize the sync feature.
Can I open the files in desktop Word or Excel without using the Sync button?
Without proper guest permissions or syncing capabilities, you are usually restricted to using Office for the Web within your browser rather than the desktop applications.
What should I do if the guest invitation link doesn't work?
Ensure you open the guest invitation link in an InPrivate or Incognito browser window. This prevents your browser from attempting to automatically log in with a different, conflicting Microsoft account.
