Outlook Back-up pst files

[bostar]

I have Windows XP Home, SP2, and I use Outlook (from Office XP/2002) for email.  I just recently had my computer reloaded and am now getting my Outlook set up again.  I downloaded and installed the Microsoft Outlook back-up pst file, (which I had used before for several years with great success) and now when I try to do a back-up of Outlook (I want it to go to "My Documents")  I get a pop-up box saying:

"Error Copying File or Folder  Cannot copy Outlook: Access is denied.  Make sure the disk is not full or write-protected and that the file is not currently in use."

When this happens, Outlook is closed....I am trying to send the back up to my documents, and I don't know anything about "write-protected".   In the Outlook Personal File Backup box, where it asks for the destination of file, I have:  <C:\Documents and Settings\Owner\My Documents\My Backup >.  I don't know if this is a correct way to tell it where I want it to go....but it doesn't seem to work.

I have uninstalled the Back-up Program, and reinstalled it, and it does the same thing. 

I would really appreciate any help anyone can give me.  How do I tell if the Personal Folders are "write protected"  And how should I fill out the line about where to send the back-up?  I am a very frustrated senior citizen who would appreciate "baby steps" on how to handle this problem.

Bostar, when I back-up my Outlook Express I have files with the .dbx extension. I never had to download any backup program to do this. Just go to OE, click on help and do a search for "back-up outlook express". It's quite straightforward.

Superdave...thanks, but I don't use Outlook Express.  I use Outlook which is part of Microsoft Office.  The personal folders in this program are pst files.

bostar Welcome Aboard !
It's possible Outlook needs to be running for this to work...try that first and if not let us know...i don't use Outlook but we have quite a few here who know it inside and out.
So try that first...

When I click on Backup, it says to close Outlook....this is what I have always done. Yesterday late, I took the "location" out of the box, and I was able to do a backup, BUT, I can't find it.  I ran a "Search" of all files and folders, hidden files and the C and D drive...but it could not find it.  But I do have two folders on the computer that have old back-ups in the, and "Search" always finds them...but not this time.   

This is really puzzling!
