How Can I Merge Outlook 2003 PSTs On Two Computers Onto One Computer

I have Outlook 2003 on my home computer. But when traveling, I have to download new emails onto my laptop which also has Outlook 2003. When I get home, how do I merge the email PSTs from the travel laptop into the Outlook PSTs on my home computer. The PST/email folders have the same names on both the home computer and laptop.

If you're using IMAP, the server should not delete the e-mails and when you use your home computer Outlook should fetch them. Leave a copy of the message on the server is missing in Outlook - Outlook | Microsoft Learn

Try that instead of trying to battle a merge.

There are however several PST merging programs out there, but the programs I found are all payware. If that's something you're interested in I can give the links.

Thanks F22 Simpilot. I'm using POP but I don't want to try getting into third party programs.
If I select Do Not Import Duplicates on Import Personal Folders, would that accomplish what I want - to just move over new emails from the laptop?

You can try that, but I'd backup the .pst file/s first. I don't use Outlook but rather Thunderbird so I'm not very familiar with Outlook. Again. IMAP would allow you to keep copies on the server so that when you do use more than one computer with Outlook all Outlook instances should be able to fetch from the server and sync. I know this to be true because I use Thunderbird on more than one computer.

You probably know this, but posting for posterity.

By the way. if you use Everything.exe and in the search box enter .pst you'll find them right away. You can then right click the .pst files in Everything.exe and 'open the path' to where they are. Or copy/paste from Everything.exe to the desktop or what ever as a temp backup.

The x64 bit installer is probably what you're after.
