Convert ost to pst, outlook 2007

I have a large OST file I need to convert to PST.

Are there any free software solutions to complete this job? or other alternatives?  are there any reliable programs for under $20?

Is this a personal computer or a work computer?

What platform - Windows - Mac, etc
What OS: XP, Win7, etc
What version of software: MS Outlook 2003, 2007, etc

The OST file is created when you have Outlook open - it is your emails in outlook - you can delete the OST file and it will rebuild when you relaunch Outlook.  So are you needing to backup (save) all your emails in Outlook?  What size is the folder?

Its a work computer, but the exchange server has been removed.  And he is off the sbs 2003 exchange server, he removed the acct without backup.

Sever is now sbs 2011, client terminal is windows xp.

So basically he still has the old sbs 2003 acct, which has the ost, but all he has for the email is newly added acct.  Exchange acct dumped everything " off outlook "when he deleted it.

The OST is 10gb.
Transaction-level recovery for Oracle database

Veeam Explore for Oracle delivers low RTOs and RPOs with agentless transaction log backup and transaction-level recovery of Oracle databases. You can restore the database to a precise point in time, even to a specific transaction.

Advanced Exchange Recovery is a small and easy to use program. It can convert OST to PST which you can just put the newly created PST file into the correct directory and view all emails using Outlook.

It has a trail period.

There are services out there that can do this also



Hope this helps

First of all, you can try to use the free scanpst tool provided by MS at


as follows:

1. Backup your .OST file first.

2. Rename its extension from .OST to .PST.

3. Use scanpst to repair the renamed .PST file.
