Frequently Asked Questions

Why are my Excel and Word files suddenly read-only in Windows 11?

This usually happens due to incorrect NTFS file permissions, a recent Windows update altering folder ownership, or interference from restrictive third-party antivirus software locking the files.

Will repairing Microsoft Office fix folder permission issues?

No. If the root cause is Windows 11 folder ownership or NTFS permissions, repairing or reinstalling Office will not resolve the issue. You must change the security properties of the folder directly in Windows.

Why can I create new files in the folder, but not edit the old ones?

New files are created utilizing your current user account's default ownership and permissions. Older files may still retain restrictive permissions or ownership from a previous user account or system state, keeping them locked.
