Ost to pst converter

Convert an Offline File (.ost) to a Personal File (.pst)

Oftentimes, Microsoft Outlook users who are leaving their current employer want to take their mail, calendar, or contacts with them and do one of two things - delete the Microsoft Exchange account from their profile without realizing the Contacts are stored in the Exchange account or they take the OST file with them, not realizing it can only be opened using the account that created it.

If you no longer have access to the computer that was used to create the OST or you don't have a restore point, you'll need to use a tool to recover the contents of the OST. A list of these tools is below. Note that OST2PST is free but will only work with OST files created by Outlook 2002 and older. If you aren't sure what version of Outlook you used, try it; an error means the OST is not the correct type.
