I found this thread very useful. Many thanks for DuxAranea.
I just wrote down for myself a standard procedure, how to do it and I thought I could share this with other people in more detail.

On the old computer (or under old user account):
Search for a folder, which name starts with "S-1-5-21" under "C:\Documents and Settings\User" folder.
I found this number as the folder name under my user profile: (each user profile has a different number assigned)
"S-1-5-21-602162358-1637723038-682003330-1003" in this location:
C:\Documents and Settings\User\Local Settings\Application Data\Microsoft\Credentials\S-1-5-21-602162358-1637723038-682003330-1003

Export the following key with all the subkeys to a reg file:
[HKEY_USERS\S-1-5-21-602162358-1637723038-682003330-1003\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\Outlook]

On the new computer (or under new user account):
Identify the new user credential nr in the same way. (Search in C:\Documents and Settings\User2 folder for a folder name starting with "S-1-5-21")
Save the following reg key:
[HKEY_USERS\S-1-5-21-3848782885-161907834-480387931-1639\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\Outlook]
where "S-1-5-21-3848782885-161907834-480387931-1639" was the credential nr of the new user.

We have to import in the registry the old information but keep the new credential number, so in the first saved .reg file, replace all occurences of
S-1-5-21-602162358-1637723038-682003330-1003 with S-1-5-21-3848782885-161907834-480387931-1639

Import the changed .reg file.

Start Outlook.
Done.
It will still ask you for the account passwords the first time when you do Send/Receive.

Before doing this I made a mistake to configure the Outlook to use the .pst file from another location and after I imported the .reg file, it gave me an error, because it couldn't locate the .pst file in the old place. I just had to choose the file from the new place and it was done.
But it would have been easier to do this procedure first for importing the email accounts.

Backing Up Your Settings and Preferences
You might want to make a backup file of your settings and preferences if you are going to reinstall Outlook or if you are going to move to another computer. To back up your Outlook preferences and settings, (as well as preferences and settings for other Office applications), do the following:

From the Windows XP Start Menu, select All Programs > Microsoft Office > Microsoft Office Tools > Microsoft Office Save My Settings Wizard.


Follow the instructions provided by the wizard.

NOTE: The Save My Settings wizard backs up only your preferences and settings, such as your email account setup, display preferences and so on. To back up data such as email messages, your local address book, tasks, and so on, use the archive feature.

To restore your settings, run the Save My Settings wizard again and select the option to restore the settings.

I used the Windows 2003 Office Tool to create file to save my Outlook 2003 email accounts as described in prior posting. This was on a fully-updated XP Pro workstation. I then imported the file into Outlook 2003 on Vista Home Premium. Now I can't use Outlook 2003 on the Vista box b/c I get an error "Can't find file Outlook1.pst. I did a full search on both the Vista and XP Pro boxes and could find no such file

I uploaded one pst file containing my email and folders. I uploaded a second containing my email addresses. Both of those worked great.

I never uploaded any file or created any file named Outlook1.pst.

It never amazes me how low Microsoft - the world's richest corporation - will go to force people to buy their newest programs. We have laws against monopoly and these laws should be used be break up this blood sucking gargantuan into smaller companies just like we did to the phone companies. The result of breaking up the phone companies is our modern communications revolution and rock bottom pricing. Microsoft should be broken up immediately and all of the bloodsucker executive who dream up these flaws put in the slammer. I remember when I first bought Outlook 2003. Immediately upon installing I could not longer send any file from a program through Outlook 2003 such as MS Word, PowerPoint, etc. as I could with Outlook 2002 - the objective being, of course, to force me to buy Office 2003 Suite from these blood sucking monopolists. Yuck!

Now that I am through with my diatribe, could ANY non-Microsoft employee out there please help me solve this issue?

If you don't like my rant, let me know. :=)

DuxAranea's method works perfectly for XP and Vista, but with one caveat: you must edit first the exported registry file to replace the user number (S-1-5-21..., etc.) from your old computer with the user number on the computer to which you are transferring the accounts. Use the find/replace option in notepad to make this simple.

You will also need to copy all of the .pst files from your "C:\Documents and Settings\[your user name]\Local Settings\Application Data\Microsoft\Outlook" folder to an identical folder on the computer you're transferring to.

I have an XP machine that's on its last legs and I'd like to copy all the old messages in Outlook Express to the new computer's Outlook Express (now called Windows Mail). Windows "Easy" Transfer is not working so my steps so far:
in Outlook Express, File > Export > Messages

BUT I get a notice : This will export messages from Outlook Express to Microsoft Outlook or MS Exchange.

However, I want to export them to a new computer and into Windows Mail, not into Outlook or Exchange. Will this erase all my old messages and not successfully transfer them to this program? A bit hesitant to try.

Many thanks!

From what i have done before and just done, i was able to just copy the key in the profile that has multiple subkeys underneath it that equal the number of accounts i have, labled

HKEY_USERS\S-1-5-21-1644491937-790525478-725345543-1003\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\Doug 3/08\9375CFF0413111d3B88A00104B2A6676

It moved all my accounts and i didnt even have to input my passwords.

don't bother! here is the cracked version of ABF outlook backup here I just upload it! enjoy

I tried to find a solution to this for ages and the I found the Microsoft, Save my settings wizard. This successfully exported all my outlook accounts details etc. It seems microsoft moved the account feature out of outlook itself but didnt really tell anybody. I had a Eureka moment when I found it.

PROGRAMS>MICROSOFT OFFICE TOOLS> SAVE MY SETTINGS WIZARD.

Cheers

I don't have this feature in office 2007!...I installed the hole office except groove, info path ...maybe microsoft had that feature in 2003 but now they want to make people very nervous! so for that reason I will use ABF

BTW, you can use
[HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\Outlook] to get the account settings as well. Much easier than trying to figure out your GUID.

Your method works perfectly.
Thanks a lot...
