"I have been trying to add a PST file to Outlook and it is not recognized as an Outlook data file, please help me to fix this error!"
Outlook is a very useful email client, but it isn't without its flaws. One particular error that users reportedly encounter is "the file is not an Outlook data file". If this is something you've seen then don't worry, we've got some solutions for you to try.
After a lot of research and careful testing, our team was able to find out what the most effective solutions for this error are. Check them out below.
Attempting to open a PST file that's"Read-Only" can cause complications as Outlook won't be able to make the required changes.
Step #1 - Locate the PST file and right-click on it.
Step #2 - Select "Properties" and a window will pop up.
Step #3 - Under the "General" tab, uncheck the "Read-Only" setting.
Additionally, if you're accessing a file from a USB flash drive, try copying it to your computer's storage instead. Both of these solutions can resolve "Read-Only" issues.
If the file issue is internal, then verifying that the file isn't Read-Only won't help. Fortunately, when you install Outlook, it comes with a built-in tool called ScanPST which scans the file and attempts to repair any internal errors. Here's how to access and use it.
Step #1 - Open a folder window and go to the location "C:\Program Files\Microsoft Office\Office16".
Note: the install folder location will differ depending on if you changed the default install location and what version of Microsoft Office you use.
Step #2 - After you are in the install folder, run the tool "ScanPST".
Step #3 - Click the "Browser" button and select the PST file that you can't open.
Step #4 - Click on "Start" and the tool will now begin a scan.
Step #5 - After the scan is complete, if any errors are found then you must click "Repair".
Step #6 - In just a few minutes the repair will be complete.
Not many programs come with built-in repair tools which is why using ScanPST to fix "the file is not an Outlook data file" is worth trying. However, there are some limitations to this tool:
You cannot use ScanPST to repair PST files that are larger than 2GB
Some versions of Microsoft Office don't include ScanPST
If you chose the custom install option, you may not have ScanPST
If the file has a lot of corruption then it may not be repairable
Overall though, it's definitely worth checking out ScanPST.
