When a File Is Locked or Open Somewhere Else

Summary

This article explains why a Word, Excel, or PowerPoint file stored in Microsoft Teams, SharePoint, or OneDrive is sometimes locked, even though two people can normally edit the same file at the same time. It describes how to tell who is holding a file open, what checking a file out does, and how to keep working while a lock clears.

Body

Issues

  • My file says it is locked for editing and I cannot save my changes.
  • How do I find out who has a file open in Microsoft Teams?
  • What does "checked out" mean, and how do I check a file back in?
  • Two of us cannot edit the same document at the same time.
  • A colleague left a file open and went home. Can I still work on it?
  • What is AutoSave, and how do I edit a copy instead of the original?
  • I get a message saying my edits conflict with edits from others. What do I do?
  • Word shows an "Upload Failed" bar and turned AutoSave off. How do I save my work?
  • My spreadsheet opens read only even though I am allowed to edit it.
  • How do I release a locked file on a Mac?

Environment

This article applies to Bowdoin College faculty and staff working with files stored in a Microsoft Teams channel, on a SharePoint site, or in OneDrive for work or school. A Bowdoin account and permission to open the file are required.

  • People: Bowdoin faculty and staff who share Word, Excel, and PowerPoint files with colleagues.
  • Systems: Word, Excel, and PowerPoint, both in a web browser and as installed desktop apps, reached after signing in at https://office365.bowdoin.edu. Menu wording differs between the web versions and the installed apps, and between app versions.
  • Computers: Bowdoin-issued Windows 11 computers and Bowdoin-issued Macs running macOS Sequoia (15.x), Tahoe (26.x), or newer, plus iPad running the current version of iPadOS. Personal computers are supported on a best-effort basis only.
  • Labels: in some versions of Microsoft Teams a channel's Shared tab is labeled Files. Both labels open the same place.
  • Not in scope: files on the Microwave department drive (J:) or your personal drive (H:), where opening a file has always locked it for everyone else. Storing files in Microsoft Teams, SharePoint, or OneDrive removes that restriction for current Office formats.
  • Not in scope: getting back a file that was deleted. Deleted items are recoverable for 93 days, and the steps are in How to Recover Documents in OneDrive, Teams, or SharePoint in the Related Articles section.

Resolution

Locked for editing and checked out are two different states

A file is locked for editing when an app is holding the file open. A lock is temporary, and nobody chose it. Microsoft lists three causes for a lock: another person is editing the file, an Office app is running in the background with the file already open, or the file was marked as final and can no longer be updated.

A file is checked out when someone deliberately reserved the file. Colleagues can see a checked-out file but cannot save changes to it until the file is checked back in. To reserve a file, open the channel's Shared tab or the SharePoint library, select the file, choose More options ("..."), and select Check out. The same menu offers Check in and Discard check out.

Important: With the right permission you can check in a file that a colleague checked out. Checking in someone else's file overrides their reservation and discards any changes they had not yet checked in, so ask the colleague first whenever you can reach them.
Note: Microsoft's guidance is direct: if you want to edit an Office document at the same time as other people, do not check the document out.

See who has a file open

  • When a file is locked, the message that appears names the person holding the file.
  • Once a Word, Excel, or PowerPoint file is open, the initials of everyone currently in that file appear near the top of the window. Select a set of initials to see the full name.
  • In a channel's Shared tab or in a SharePoint library, a checked-out file shows a marker next to the file name, and the "Checked Out To" column names the person who reserved the file.

Which files two people can edit at the same time

Co-authoring, which lets two or more people edit at once, is supported only on the current Office formats: .docx, .xlsx, and .pptx. Co-authoring is not available for documents protected with Information Rights Management (IRM) or Rights Management Service (RMS).

One person at a time is the practical limit for these files:

  • Older formats such as .doc, .xls, and .ppt. Open an older-format file and use File > Save a Copy to save the file in the current format, then work in the new copy.
  • Portable Document Format (PDF) files, and files created by applications other than Word, Excel, and PowerPoint.
  • Files you do not have edit permission on. Those files open read only, and a Team owner or the file's owner can grant edit permission.

AutoSave changes what saving means

AutoSave is on by default for files stored in OneDrive or SharePoint, and AutoSave writes your changes every few seconds as you work. There is no moment when you decide to commit your changes, and File > Save As is replaced by File > Save a Copy.

To try something out without changing the shared file, choose File > Save a Copy before you start editing. Making a copy afterward does not help, because AutoSave has already written your edits into the shared file. To turn AutoSave off for every file, go to File > Options > Save and clear the AutoSave checkbox.

When your changes conflict with someone else's

If your edits cannot be merged with a colleague's edits, Word shows an Upload Failed bar and turns AutoSave off. Word then offers three choices:

  • Save a Copy keeps your work in a separate file. Note where the copy lands so you can merge the copy back into the shared file later.
  • Discard Changes throws away your unmerged edits and keeps the shared file as it stands.
  • Resolve steps through each conflicting change so you can accept or reject the change one at a time.

If the file reopens with the conflicts shown as tracked changes, select Review Changes to work through them. Nothing is lost in a conflict, but the result can be two files, so merge the copy back and delete the copy once the shared file is correct. A file that appears twice with your computer name added to one copy is not a conflict; the OneDrive sync app needs its credentials refreshed.

Someone left the file open and went home

Some applications hold a lock until the app is closed, not until the person stops typing. A colleague who left Excel open on a desktop computer in an empty office is still holding that file, and nobody can release the lock remotely.

  1. Ask the colleague to close the app that is holding the file. Asking is the cleanest fix and usually the fastest one.
  2. If the colleague is unreachable, open the file read only and work in a copy, then move your changes into the shared file once the lock clears.
  3. If the content matters more than the file itself, open the file's version history and copy what you need out of the most recent version. For the steps, see See and Restore an Earlier Version of a File in the Related Articles section.
Warning: If a lock stays in place after everyone confirms the file is closed, contact the Bowdoin College Service Desk instead of deleting the file and recreating it. Recreating a file breaks every link and shortcut that pointed at the original.
