Check Out Button Is Missing for Office Files: Causes and Workarounds

When you open an Office file stored in a SharePoint document library, the Check Out button may be missing from the ribbon or the file context menu. This prevents you from locking the file for editing, which can lead to version conflicts if multiple users edit the same file at the same time. The cause is usually a site collection feature setting or a library configuration that disables the check-out requirement. This article explains why the Check Out button disappears and provides step-by-step workarounds to restore it.

Why the Check Out Button Disappears for Office Files

The Check Out button is a SharePoint feature that lets you lock a file so that only you can edit it while you have it checked out. When the button is missing, it means one of two things: the document library does not require check-out, or the file is configured to open in a desktop client application instead of the browser.

SharePoint document libraries have a setting called Require Check Out. When this setting is turned off, the Check Out button does not appear in the ribbon or the file context menu. Additionally, a site collection feature called Open Documents in Client Applications by Default can override the library behavior. When this feature is active, Office files open directly in the desktop app (Word, Excel, PowerPoint), and the browser-based Check Out button is hidden. The workaround is to adjust these settings so that check-out is required and files open in the browser.

How the Check Out Button Works in Browser vs Desktop App

In the browser version of SharePoint, the Check Out button appears in the toolbar at the top of the document library when you select a file. In the desktop app, you can check out a file from within the application (File > Info > Check Out), but the SharePoint browser interface will not show the button if the library does not require check-out. The workarounds in this article focus on making the Check Out button visible in the browser, which is the most common scenario for users who expect to see it.

Steps to Enable the Check Out Button in SharePoint

Follow these steps to restore the Check Out button. You need at least Edit or Contribute permissions on the document library to change its settings. For the site collection feature, you need Site Owner or higher permissions.

1. Open the document library settings
   Navigate to the SharePoint document library where the Check Out button is missing. Click the gear icon in the top-right corner and select Library settings. If you do not see Library settings, click the Library tab in the ribbon and then click Library Settings.
2. Enable Require Check Out
   In the Library settings page, under General Settings, click Versioning settings. Scroll to the Require Check Out section. Select Yes under Require documents to be checked out before they can be edited? Click OK at the bottom of the page. This setting makes the Check Out button appear for all files in the library.
3. Disable site collection feature for client applications
   If the Check Out button still does not appear after step 2, the site collection feature may be overriding the library setting. Go to the site collection root (the top-level site). Click the gear icon and select Site settings. Under Site Collection Administration, click Site collection features. Scroll down to Open Documents in Client Applications by Default. Click Deactivate. This forces Office files to open in the browser, where the Check Out button is visible.
4. Set file open behavior to browser
   As an alternative to deactivating the site feature, you can set the library to open files in the browser. In Library settings, under General Settings, click Advanced settings. Under Opening Documents in the Browser, select Open in the browser. Click OK. This setting tells SharePoint to open Office files in the web app, which displays the Check Out button.

If the Check Out Button Still Does Not Appear

After applying the steps above, the Check Out button should appear. But if it remains missing, check the following common issues.

File is already checked out by another user

If a file is already checked out by someone else, the Check Out button is replaced with a Discard Check Out option for that user. Other users see the file as read-only and cannot check it out. To verify, hover over the file name and look for a green check mark icon. If the icon shows a person silhouette, the file is checked out by another user. Ask the user to check in the file.

Library is configured to open files in the client app

Even if you set the library to open in the browser, the user’s own Office settings can override that. In Word, Excel, or PowerPoint, go to File > Options > Advanced. Under SharePoint, uncheck the box that says Open SharePoint files in the client application by default. Restart the application and try again.

Site collection feature is not accessible to non-owners

If you are not a site collection owner, you cannot deactivate the Open Documents in Client Applications by Default feature. In that case, ask your SharePoint administrator to deactivate it or to set the library to require check-out at the site collection level using PowerShell or the SharePoint admin center.

Setting	Effect on Check Out Button	Best Use Case
Require Check Out enabled	Button appears in browser and ribbon	Libraries where multiple users edit the same file
Open Documents in Client Applications by Default active	Button hidden in browser; check-out available in desktop app only	Users who prefer desktop Office apps and do not need browser check-out
Library set to Open in the browser	Button appears in browser regardless of site feature	Teams that collaborate in the browser and need version control

Now you can enable the Check Out button by adjusting the Require Check Out library setting and disabling the site collection feature for client applications. If you work in a library that requires strict version control, also enable Content Approval and Major/Minor versioning to track changes. An advanced tip: use SharePoint Power Automate to send an email when a file is checked out for more than 24 hours, preventing abandoned check-outs.
