If you have orphaned your OST file then you have lost the data in it. It can
be recovered but at considerable expense. You can open PST files via File |
Open but I'd say your OST contained most of your data.

For some time I had been running Outlook 2003 at home after the business
closed and I brought this PC home. It was on a Microsoft Exchange server.
Of
course, I was no longer connected to the server but all the data was still
there. Now, I had to re-install Windows XP Pro but was able to save the
various Outlook files. Although I have found various .pst and .ost files I
cannot get Outlook to bring up the old data, particularly the various
contact
files. Any suggestions will be appreciated.
