Solutions for the error “Outlook Exited without Closing Outlook Data File”
Here are some solutions to resolve the “Outlook Exited without Closing Outlook Data File” error:
Method 1: Restart the System
Initially, if you haven’t already, restart your computer. Such errors may occasionally result from transient storage- or memory-related problems with the system. So you might be able to resolve the issue by restarting the system.
Try the next solution if the system reboot didn’t work.
Method 2: Ensure that Outlook is not active in the background.
Make sure there isn’t a previous instance of Microsoft Outlook operating in the background in order to prevent or fix this error. Follow these steps to do so:
- Press the Ctrl, Shift, and Esc keys. The Task Manager window will be displayed as a result.

Look for any instances of “Outlook.exe” in the Task Manager window and shut down or terminate them.
Once you’ve terminated every Outlook.exe instance, try to launch Outlook to see if the issue has been fixed.
Method 3: Disable Add-ins in Outlook
If the above techniques didn’t help, you can try disabling any add-ins that Outlook may be having issues with or that are blocking it from functioning.
- Shut down every Outlook instance.
- Click “OK” or press the “Enter” key, then type Outlook.exe /safe by using the Windows + R keys. As a result, Outlook will launch in safe mode.
- Holding down the “Ctrl” key while selecting the Outlook application icon on your Windows laptop or PC enables you to launch Outlook in safe mode as an alternative.
- Whenever Outlook launches in safe mode, go to File > Options > Add-ins.
- Choose “Go” from the menu.

- Select every add-in and then click OK. All installed add-ins in your Outlook client will be disabled as a result of this.
- Relaunch Outlook as usual. If it launches without a hitch, you must identify and get rid of the problematic or incompatible add-in in order to permanently fix the issue.
- Click the Go button after navigating to File > Options > Add-Ins to do this.
- Restart Outlook after activating one add-in this time. Take a look at Outlook for a while. Activate another add-in if Outlook doesn’t crash.
- Up until Outlook shuts down or crashes, repeat the prior procedure. This will enable you to identify the flawed or unworkable add-in.
- Remove or delete the add-in when it is located.
Method 4: Repair Outlook Data File (PST)
All of the mail items, including emails, attachments, contacts, notes, tasks, and other objects, are stored in a PST file by Outlook (with a POP3 account). Due to oversizing or system-related problems, the PST file may get big or corrupted, making Outlook crash or giving errors.
If the PST file is corrupted, try to fix it by doing the following:
To locate and launch the scanpst.exe program, navigate to the MS Office installation folder, which is found in the C: Program FilesMicrosoft Office directory. Depending on the version or edition of Outlook and Windows, the scanpst.exe location could change slightly.

- Start up scanpst.exe.
- To choose the PST file, click the Browse button. The AppData folder is usually where you may find the PST file.
- Select the PST file and then click Start. The PST file will now begin to be scanned. Attend to the scan’s conclusion.

- After the scan is complete, select Repair.
- The PST file will begin to be repaired by the utility.
Start Outlook after the PST file has been repaired. ‘Outlook exited without closing Outlook Data File’ should be resolved at this point.
Due to the following restrictions, scanpst.exe can occasionally fail to fix the PST file or crash during the repair process:
- A PST file that is extremely corrupt, damaged, or encrypted cannot be repaired.
- If the PST file is more than 2 GB, it might not repair.
In these situations, you can use an advanced Outlook PST repair application, like CubexSoft Outlook Converter, to download, install, and fix the corrupt or damaged PST file.
