Just a guess...

Did you copy this pst onto your desktop from a CD?

If so, then select the properties of the file and turn off the
Read Only check mark. To select the properties, just
right click the file and select "Properties".

Once you have done this you should be able to open
the data file into your Outlook program.

I have a .pst file on my desktop. I am trying to open it with Outlook
2003. But it says " it is not a personal folders file".
Please tell me what am I doing wrong.
