Have you ever encountered the frustrating situation where you try to open and check out an Enterprise project, only to be greeted with a warning that it’s already checked out in another session? Well, you’re not alone; it happens to project managers more often than you might think. In this blog post, I’ll guide you through three techniques to check in a stuck project.

The Problem: An Enterprise Project Is “Stuck” in a Checked Out State
Have you ever encountered an error dialog like the one shown in the following illustration? If yes, what does this error dialog mean? It indicates that your project has become “stuck” in a checked-out state in either Project Online or Project Server. Until you “unstick” the “stuck” checked out project, you will not be able to edit the enterprise project. So, let’s explore three methods you can use to resolve this issue.

Method 1: Force Check In Stuck Projects with Project Web App
Complete the following steps to “unstick” the “stuck” checked out project using Project Web App:
- Launch your preferred web browser and navigate to the Home page of Project Web App.
- Click the “Projects” link to navigate to the Project Center Page.
- Click the “Projects” tab to expand the Projects ribbon.
- In the Navigate section of the ribbon, click the “Check In My Projects” button.
- On the Force Check-In Enterprise Objects page, select the checkbox for your “stuck” enterprise project.
- Click the “Check In” button and then confirm the action in the confirmation dialog.
- Try opening and checking out your Enterprise project again.
If this method does not work, and the enterprise project is still in a “stuck” checked out condition, then try the second method.
Method 2: Cleanup Cache in Microsoft Project
Complete the following steps to “unstick” the “stuck” checked out enterprise project using the Microsoft Project Professional desktop application:
- Launch Microsoft Project Professional and connect to Project Web App.
- Click the “File” tab and then click the “Options” button in the Backstage.
- In the Project Options dialog, click the “Save” tab.
- Click the “Cleanup Cache” button at the bottom of the Save page.
- In the Cleanup Cache dialog, click “Project Filter” pick list button and select the “Projects Checked Out to You” item.
- Select your “stuck” project and click the “Remove from Cache” button.
- Click the “Yes” button in the dialog to confirm the deletion.
- Try opening and checking out your enterprise project again.
If this method does not work, and the enterprise project is still in a “stuck” checked out condition, then try the third and final method.
Method 3: Rebuild Local Project Cache
Complete the following steps to “unstick” the “stuck” checked out project deleting and rebuilding the Local Project Cache:
- Close Microsoft Project Professional completely.
- Launch your File Explorer software.
- Click the “View” tab to display the View ribbon.
- Select the “Hidden Items” checkbox in the Show/Hide section of the ribbon, if not already selected.
- Navigate to: `C:\Users\YourUserID\AppData\Roaming\Microsoft\MS Project\VersionNumber\Cache`.
- Delete the contents of the “Cache” folder.
- Launch Microsoft Project, and it will rebuild the Local Project Cache.
- Open and check out the previously “stuck” Enterprise project.
Now you have three effective methods to resolve the issue of a “stuck” enterprise project. Remember to try these methods sequentially, and you may find that one of them does the trick for you.
