OneDrive file locked for editing by another user — but nobody has it open
You open the spreadsheet and Excel tells you it is locked for editing by a colleague. You ask across the office; they closed it an hour ago. Or it names you. Or it names someone who left last year. The lock is real — something is holding the file — but the something is rarely a person sitting with it open. Here is where the lock actually comes from, the ten-minute rule that clears most of them, and what to do about the ones that stay. Rated 4.9 on Google.

/01 — WHERE THE LOCK COMES FROM
Four things that hold a file, and only one of them is a person
When a file lives in OneDrive or SharePoint and someone opens it in the desktop version of Word or Excel, the service can place a short-term lock on it so two people do not save over each other. Modern files with AutoSave on do not need the lock, because everyone edits together. The lock appears when something has stopped that from being possible.
- A crashed or interrupted session. Excel closed unexpectedly, a laptop lid was shut, the Wi-Fi dropped mid-save. The program is gone but the service has not yet heard, and it keeps the lock for a while in case the person comes back. This is the commonest case by a distance.
- You, somewhere else. The same file open on your phone, on another PC, in a browser tab you forgot, or previewed in a Teams tab. To the service, that is another user.
- A file that cannot co-author. Old formats — .xls, .doc — files with macros, and anything opened with AutoSave off fall back to one-at-a-time editing, and the first person in holds it until they close it.
- A check-out. Some SharePoint libraries are set to require files to be checked out before editing. A checked-out file is locked to that person until they check it in, and if they have left, it stays that way until an owner intervenes.
// WINDOWS PCS ONLY
We do not support OneDrive on Apple Macs, iPads or iPhones. Apple does not allow our remote-support tool to take control of an iPad or iPhone (an Apple restriction), and our remote support covers Windows PCs only. On an Apple device, Microsoft’s own OneDrive help is the place to start.

A lock left by an interrupted session clears itself after a short while — roughly ten minutes is a good working figure. So the first move is unglamorous: make a cup of tea. Full detail in the guide below ↓

02Find the copy of yourself that is holding it
Being told you have locked a file against yourself is common enough to be funny once. The service is right: some device signed in as you has the file open, and it is usually one of these. Full detail in the guide below ↓

A lock that outlives the ten-minute rule and has no live owner needs a little more. A file checked out to someone who has gone. Full detail in the guide below ↓

Wait, and find out who really has it
A lock left by an interrupted session clears itself after a short while — roughly ten minutes is a good working figure. So the first move is unglamorous: make a cup of tea. Meanwhile you can open the file read-only and copy anything you urgently need out of it.
If it is still locked afterwards, find out who genuinely has it. Open the file’s location in a web browser rather than in File Explorer. In OneDrive or SharePoint, the file’s details pane shows who last modified it and who it is shared with, and opening it in the browser shows who is currently in it. That is the truth; the name in the desktop error is a best guess that can be hours out of date.
If the name is a colleague, ask them to close it everywhere — the phone counts, the second monitor counts, the browser tab from this morning counts. If the name is yours, section 03. If the name is someone who has left, section 04. And if the file is on an old-fashioned shared drive rather than in OneDrive, the tools are different and we have a separate guide for that.
/03 — WHEN IT IS YOU
Finding the copy of yourself that is holding it
Being told you have locked a file against yourself is common enough to be funny once. The service is right: some device signed in as you has the file open, and it is usually one of these.
- Another computer. The office desktop still has it open from yesterday; the laptop at home never shut it. Close it there, or if you cannot get to that machine, sign it out of Office remotely from your Microsoft account’s device list.
- Your phone or tablet. The Office or OneDrive app opened it last week and has held it since. Close the app fully, not just switch away from it.
- A browser tab. The file open in Excel in the browser, three windows back.
- Teams. A Teams tab or preview pane counts as having it open.
Close all of them, wait the ten minutes, try again. If it still names you, sign out of OneDrive on this PC and back in, which drops any stale session it was holding on your behalf.
/04 — THE ONES THAT STAY
Stale locks, check-outs, and the leftover lock file
A lock that outlives the ten-minute rule and has no live owner needs a little more.
- A file checked out to someone who has gone. In a library that requires check-out, an owner of the site can discard the check-out from the library’s settings, which releases the file and keeps the last checked-in version. That is a site-owner job, and it is one of the things to do when someone leaves.
- The leftover lock file. When Word or Excel opens a document, it creates a small hidden companion file in the same folder whose name starts with
~$. A crash can leave it behind, and while it exists Office believes the document is open. With the document definitely closed everywhere, show hidden files in that folder and delete the~$file. It is safe; Office recreates it next time. - A lock the service will not drop. Rare, but it happens. Copy the file to a new name, carry on working in the copy, and delete the original once its lock finally clears. Nothing is lost and nobody is waiting.
If locks like this are a weekly event in your office, the cause is almost always one of the habits in section 05, and that is a ten-minute conversation rather than a recurring emergency.
/05 — STOP IT HAPPENING
The habits that make locks rare
- Modern formats. Save old .xls and .doc files as .xlsx and .docx and they can co-author instead of locking.
- AutoSave on. With it on, several people can be in the same file at once and nobody holds it.
- Open from the shared place. Not from an emailed copy, not from a download.
- Shut down, do not just close the lid. A laptop that goes to sleep with a file open is the single biggest source of stale locks.
- Only require check-out where it is truly needed. It is the right setting for a document that must have one author at a time; it is the wrong default for a whole library.
- Include it in leaving. When someone goes, an owner checks their files in and reassigns what they owned, or the office inherits their locks.

// GOOD QUESTIONS
Frequently asked
Nobody has the file open, so why does it say it is locked?
Because a lock is left behind when a session ends badly — a crash, a laptop lid shut, the Wi-Fi dropping mid-save — and the service keeps it for a while in case the person comes back. Wait about ten minutes and try again. If it persists, open the file’s location in a browser: the details there show who truly has it, which the desktop error often gets wrong.
How long does the lock last?
A lock from an interrupted session usually clears itself within about ten minutes of the program going away. A lock from a file genuinely open somewhere lasts until that copy is closed. A check-out lasts until the file is checked in or a site owner discards the check-out.
Can I just make a copy and work in that?
Yes, and for an urgent job it is the right move: open read-only, save a copy under a new name, carry on. Just remember to reconcile it with the original once the lock clears, or the office ends up with two versions. Version history on the original will show you anything that changed in the meantime.
It says the other user is me
Then some device signed in as you has it open: another computer, your phone, a browser tab, a Teams preview. Close it everywhere, wait the ten minutes, and if it still names you, sign out of OneDrive on this PC and back in to drop the stale session.
It is checked out to someone who left the company
An owner of the SharePoint site can discard the check-out from the library’s settings, which releases the file and keeps the last checked-in version. It is worth doing for everything that person had checked out at once, and it belongs on the list of things to do whenever someone leaves.
