If your Microsoft Outlook Data File (.pst and .ost) won’t open, or if you suspect the file is damaged, use the PST Viewer (pstwalker.exe) to open and recover emails in this data file. When analyzing files and extracting data, PST Viewer (pstwalker.exe) does not modify the source file in any way, excluding even the slightest possibility of causing further damage to it.
The PST Viewer (pstwalker.exe) tool doesn't connect to an Exchange mailbox. If you're using a Microsoft Exchange account and your offline Outlook Data File (.ost) is orphaned, you can safely open the file. The tool only looks for errors (corruption), and there are any, gives you the opportunity to allow the tool to extract your emails. Software performs a read-only operation to read messages from .ost file and doesn't modify any metadata from .ost files.
PST Walker is a good solution, when you need to view your mailbox. You may need it
in a business trip, when connection with mail server is lost and there's no way
to read it. It is very important, when you use Microsoft Exchange Server
and Microsoft Outlook mail client. You may be simply out of office,
where Internet connection is absent. All of your contacts, mails, messages,
tasks and calendars are stored on mail server and there's no way to extract it
offline. You may need to send an urgent email or phone call, but contacts are
stored on server.
However, solution exists. PST Walker will help you to restore your data from files with .pst and .ost extension. This tool will work with all supported versions of Microsoft Outlook. PST Walker is so easy, that all functions can be accessed even by beginners.
Earlier versions of Microsoft Outlook (up to 2002) limits the size of Personal Folders .pst files
and offline folders .ost files to 2GB. If a new or changed item increases the size over than limit, you
will not be able to use the .pst or .ost file. Even if you delete
items from the server mailbox, the .ost file will not synchronize.
Outlook has no built-in way to reduce a .pst or .ost file that has gone over the limit. However, Microsoft provides a tool, PST2GB, to restore the file to operability. Note, however, that the utility uses a fairly radical approach to "repairing" such a file: it forcibly truncates the file at the 2 GB boundary (actually, slightly below it) and makes it readable again. Unfortunately, this means that everything after the truncation will be lost. If you can suffer the loss of the data at the end of the file (which tends to be spurious), you can use this to restore the file to working order and extract the messages within.
Instead of this utility PST Walker provides a safe approach to repair you lost data. Repairing data with PST Walker and MSG 2 PST comes down to:
- reading the corrupted .pst or .ost file
- identifying and converting data from this .pst or .ost file to Outlook Message Format (*.msg files)
- saving the recovered data to one or several new .pst files with MSG 2 PST utility
* Access to *.ost files and command line options available in Business license only.
