Synchronizing OneDrive via guest access in another company.
One user of our company (company1) has an account (email address removed for privacy reasons) on the Office 365 portal. Multifactor authentication (MFA) is used for authentication; when logging in, the user enters a temporary code into the application on their phone. With this account the user logs into the portal (company1.sharepoint.com), where he can access the documents stored there. This user has OneDrive, which successfully synchronizes documents from the company1.sharepoint.com portal to their PC. There is a second company (company2), which has provided guest access to this user to its portal (company2.sharepoint.com). The user also successfully logs into the company2.sharepoint.com portal and can also access the documents stored there. But, when trying to synchronize documents on the company2.sharepoint.com portal via OneDrive, the user receives the message: "Sorry, OneDrive can't add your folder right now". Please help me to find a solution of this problem.
