HI,

I have a very large .pst archive email file, which is way too big (more than 40gb).

It has now started cuasing problems, I cannot open it in Outlook.

I should have broken it down into smaller archive files, but never got around to it.

 scanpst.exe cannot fix it, it runs through the 8 stages, and finds issues, but when you go to fix the errors, it fails.

I can no longer open the .pst file from within Outlook.

Is there are more advanced tool to fix the errors?

Can you try importing it into a new PST?  That will probably take a while, but it might do some compacting during the import.  Newer versions of Outlook are able to open that large of a .pst file

Try importing it as suggested above and if that fails, try repairing it with Stellar PST Tools. I have done this.

There are lots of third party tools out there and I'm sure the vendors will be along shortly to recommend their brands. Just keep in mind that the "free" version generally will only tell you if it can recover the data. You'll have to buy it if you actually want it to work.

Edit: John beat me to it. Yes, Stellar is a good one.

Dear All,
The Savior has (Finally!) finished scanning the pst file.

It did not report any errors, only the option to save the scanned file as a new file.

When you attempt to save the file as a new .pst file, it is at this point that you are directed to their website to purchase an activation code, which costs $99.

My question would be, is there a possibility that the saved file will also not open in Outlook, and therefore the purchase will be wasted.

We're talking about a very large file, and it would be disappointing if the file performance did not improve post purchase.

I am concerned as The Savior did not report any errors or report having fixed any in the process of scanning the file, so although it looks like it can read and display everything in the .pst file accurately, I have no guarantees that Outlook will do the same...

Now as you find no result with your first check.

I ask you to use Kernel for Outlook PST Repair tool. The demo version will preview all emails from PST file (no size limit) and if you find result worthy only then purchase the tool at low price. Visit https://www.nucleustechnologies.com/outlook-pst-repair.html to know more about the tool and download the application.

You could contact Savior Support and ask your question about saving to a new file.

Also try Stellar as has been suggested a couple of times.

Will do. Will contact Savior and report back

Will try Stellar in the meantime....

Just an update - Stellar is still scanning. The two programs look identical. The main difference is that the savior is a one year licence, whereas Stellar is ongoing., which looks much better value?

Savior support came back and re-assured that once the product was purchased it would detail all errors fixed and would definitely work in Outlook.

Main difference so far seems to be the much higher price for Savior.

Gents - an update, Stellar finished scanning, and the file works as expected in Outlook, although it doesn't have exactly the expected and same folder structure, but everything seems to be there, and I can at least open the file.

Thank you all for advice.
