Copying Outlook accounts and emails is a rather tricky task. You can easily copy the PST file and import it in the new computer, but that will not copy your account setting, worse, The new outlook will not be able to tell if the emails you copied are the same as those still on the server (if you’re keeping a copy on the server that is) and you’ll end up downloading all you inbox emails again, creating duplicated emails (the copied and the downloaded ones).
I assume that the new outlook is fresh and doesn’t contain any data, if you follow this guide, the emails and accounts of the new outlook will be overwritten.
To transfer all your email (sent & inbox) to a new computer do the Following
1. On the old computer, find your PST files, you can do so by navigating to account settings and then data files
2. Copy the PST files to a removable storage for transfer to the new computer.
3. Hit WinKey + R and type regedit to start the registry editor. navigate to : HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\Outlook . right click outlook and select export. save the registry to the removable drive.
4. Now go to the new computer. paste the PST files to the same folder you found them in (in outlook 2010 it is in documents\outlook files)
5. Now start regedit as before, and navigate to the same key. export it to a safe location in case you need to rollback. then delete they key.
6. double click the registry you imported from the old machine and install it.
Now start outlook, if there’s a message asking for the location of the datafiles, it means that you didn’t copy them to the same location, just browse to the copied files and click open.
7. You should now be able to see your old emails (inbox, sent, junk, etc) and find your old accounts in the account settings page.
8. If you’re unable to send \ receive because of the following error outlook unable to open data files. there’s a little trick that I did to bypass it.
A. Open account settings and click you email address.
B. on the bottom of the screen click change folder. then create a new data file (dont use the imported PSTs)
C. save everything, then send receive. as soon as it start downloading cancel the process.
D. repeat the process and change the folder to the imported PST’s inbox folder.
E. Send receive again, it will work! DON’T ASK ME WHY, it just does.
Hope this will work for ya.
