this is the way i have been backing up, and restoring my outlook files, since win2k came out.
now using winxp, and outlook2002.
i do a daily copy of the following folders (all files in the folders).
C:\Documents and Settings\<username>\Application Data\Microsoft\Outlook\*.* (*.pst files, ect)
C:\Documents and Settings\<username>\Local Settings\Application Data\Microsoft\Outlook\*.* (
the above assumes you have win2k or winxp. if win98 or me, your path would be similar.
i then, on my new install of outlook, start it up, set up my account, i dont retrive any new emails
at this point, i then close outlook down. this will create the above pathways. i then copy the
contents of the above folders to the newly created folders, over writting any existing files.
i then start up outlook, and there are all my emails. the address book is a little harder.
you go into; toos-->email accounts-->view or change existing directories or address books,
then 'next' button. select 'outlook address book' then press 'remove'. then press 'add',
choose outlook address book, and creat it. you will get a message, about having to restart
outlook. close outlook down. restart it. create a new email, select the 'to' button, which brings
up the 'select names' box. to the right of that there is a pull down arrow, well, pull it down, and select contacts. nothing will appear. close the 'select names' box, and select 'to' again. this time you should have a 'select names' box, with all your old addresses in it. i might have some of the details off slightly, doing it from memory. and i am on pain killers, because is severly cut 3 of my fingers (broke one, lost 2 nails), and i am typing with only my thumb on my left hand. normally i can type with all 10 fingers.
this is my method, because it has worked for me for 5 years strait. and i re-install windows about every 2 months.
