OST files



A PST file was created with Office 2007 and was put on XP. When the
government decided to get Vista (should have waited for Windows 7), The file
was moved to an external hard drive and then when it was put back in the same
folder of Windows Vista, it won't find it because it says it is an OST file.
This is a problem! We need to access this file and can't. Can we convert it
somehow (if so, with what program) or can somebody tell me what good an OST
file is if you can't use the darn thing?

What is the error message, work for word? If the extension is PST, it’s a
PST and was not converted to an OST.

See http://www.slipstick.com/problems/scanpst.asp for information on
repairing a damaged pst.

There is no error message. I put the file back into the same location (the
default hidden folder) on outlook and when I go to select it, it isn't there.
If I open the folder through the explorer, it will be there, but outlook
doesn't see it when I go to select it as the PST file. It is an OST file. I
need to know if there is a way to convert the file to a pst or have I pretty
much lost the information (file). Is there a program out there where I can
recover all the information on the file and then possibly re use it?

There are a couple of recovery programs out there which can also convert
ost-files to pst-file.
See http://www.howto-outlook.com/tag/data-recovery

As Diane said; a file doesn't convert itself, so you might have backed up
the wrong file before. An ost-file is nothing more that a copy of an on-line
mailbox such as an Exchange mailbox and doesn't contain any unique (mail,
contact calendar, etc...) data of its own as the original would still be in
the on-line mailbox.
