What you’re seeing
- Word or Excel says the file is locked for editing by another user and opens it read-only.
- The message names a colleague who closed the file hours ago or who is out of the office.
- SharePoint shows the document as checked out, and other people cannot save their changes.
- The file is locked by the user themselves, from another PC or an earlier session.
Common causes
Every environment is different, but these are the causes our engineers find most often:
- A previous editing session crashed or lost connection, leaving a stale lock that SharePoint has not yet released.
- The library requires check-out before editing, and someone checked the file out and never checked it back in.
- The file is in a legacy format or contains features that block real-time co-authoring, so only one person can edit at a time.
- The file is opened through a mapped drive or synced copy using an older version of Office that does not co-author.
- A macro-enabled or linked workbook holds an exclusive lock that ordinary documents do not.
Why it matters
Shared spreadsheets, schedules and price lists are often edited by many people throughout the day. A stuck lock stops everyone else, encourages people to save personal copies under new names, and leads to conflicting versions that must be merged by hand. In finance and operations, working from the wrong copy can mean wrong invoices, missed orders or payroll errors.

Frequently asked questions
Will forcing the lock to release lose anyone's changes?
It can, if the person really is still editing. We confirm whether the lock is stale and whether there are unsaved changes before releasing anything.
Why does this keep happening with the same spreadsheet?
Usually that file has a format, macro or library setting that prevents co-authoring. Identifying it typically stops the repeat lockouts.
