A Microsoft file hosting and synchronization service.
Dear Lezait123,
Good day! Thank you for posting to Microsoft Community. We are happy to help you.
Based on your description, we understand that your OneDrive Sync Conflict Section Grayed out.
Given the screenshot, if devices mentioned above are in your office, the "greyed out issue" may be related to Group Policy settings in your tenant. You may contact your IT, let him check the Coauthoring and in-app sharing for Office files section in this article. If the setting is disabled, he can choose to enable it via Group Policy according to your company's policy.
Sincerely,
Tin | Microsoft Community Moderator
