How to Check Out a File in SharePoint
Check-out locks a document so only you can edit it. It’s a tool for controlled changes, not everyday collaboration — but knowing when to use it matters.
What it is
Check-out is a SharePoint feature that lets you ‘reserve’ a file for exclusive editing. While a file is checked out to you, nobody else can change it. They can read it (the last checked-in version), but they can’t make edits until you check it back in. It’s the opposite of co-authoring, where multiple people work on the same file simultaneously.
For most everyday work, you don’t need check-out — co-authoring is faster, smoother, and how Microsoft 365 is designed to work. But check-out has a place: when you’re making sweeping changes, restructuring a document, or working on something where someone else’s parallel edits could cause real problems. Policies being completely rewritten, master templates being updated, controlled documents going through formal review — these are good check-out candidates.
The risk with check-out is forgetting to check the file back in. If you check out a file on Friday and go on leave for two weeks, your colleagues are locked out the whole time. Some libraries enforce automatic check-out for every edit; this almost always causes more friction than it prevents. Use check-out deliberately, not as a default.
When to use check-out vs co-authoring
Co-authoring (the default) is right for almost all collaboration: meeting notes, working drafts, team documents, anything where multiple people contributing makes the work better. Check-out is right when one person needs to make significant changes without interruption — and the team needs to know not to edit in parallel.
When to use this
- When you’re making major structural changes to an important document.
- When you’re working on a controlled document (policy, procedure) and want to prevent parallel edits.
- When you’re updating a template that others will use.
- When you need to ensure no one else changes a file mid-edit (e.g. critical data updates).
How to do it
- Open the SharePoint library where the file lives.
- Select the file (don’t open it yet).
- Click More options (the three dots) and select Check out.
- The file’s icon changes to show a small green arrow — it’s now checked out to you.
- Open the file and make your changes.
- Save as you go (AutoSave still works for checked-out files).
- When done, return to the library, select the file, and choose Check in.
- Add a check-in comment describing what you changed, then confirm.
Best practices
- Use check-out sparingly. Co-authoring is the default for a reason. Reserve check-out for genuinely controlled situations.
- Check files in promptly. Don’t leave files checked out overnight or before leave. Other people need access.
- Always add a check-in comment. ‘Updated section 3 with new policy’ is far more useful than no comment.
- Communicate when checking out shared files. A quick chat message (‘I’m rewriting the procedure today, please don’t edit’) saves confusion.
Common mistakes
- Forgetting to check files back in. Most ‘I can’t edit this’ helpdesk tickets are about a forgotten check-out from last month.
- Enforcing check-out on busy collaborative libraries. Forces serial editing where parallel editing would be faster.
- Treating check-out as locking for security. It’s not a permission control. Use proper permissions for sensitive content.

How do I check out a SharePoint file?
Right-click the file, choose More, then Check out. A green arrow icon appears, indicating it’s checked out to you. Nobody else can edit the file until you check it back in. Useful when you need exclusive editing access for a sensitive change.
When should I use Check Out vs co-authoring?
Co-authoring is the default and best choice for most situations — multiple people can edit simultaneously. Check Out is for cases where you need exclusive access: making sensitive structural changes, working offline, or preparing a major version where merge conflicts would be costly.
What happens if someone forgets to check in a SharePoint file?
The file stays checked out and nobody else can edit it. Site owners can force a check-in via the file’s menu (Discard check-out or override check-in). Build a quarterly check for files checked out longer than a week — they usually indicate someone forgot rather than someone working.
Does SharePoint require check-out by default?
No — by default, libraries allow co-authoring without check-out. To require check-out, go to Library Settings -> Versioning settings -> Require Check Out. Use sparingly — it disables co-authoring entirely, which most teams rely on.
