Transfer Your Outlook 2003 Emails to Gmail

Transfer Email to Google

In my previous article I detailed the steps necessary to transfer Outlook 2007 emails from your computer to your Gmail account. This how-to is a follow up to a comment left by one of my readers that pointed out that there were significant differences between Outlook 2007 and 2003. I decided to publish this article for him and for any of you who are using Outlook 2003 and would like to transfer your emails to Gmail. If you have any comments or questions, please post them below.

Note: I used Outlook 2003 and a standard Gmail account to write this article. If you use Google Apps you can use this free tool to transfer your emails.

10. You should now be able to access your Gmail folders from within Outlook. Now you can start moving the emails from Outlook over to Gmail. Click on the folder containing emails from your Outlook file, select the emails within the folder (or the entire folder) and drag it over to the folder list. This will start the transfer of e-mails from your Outlook files to Gmail’s servers.

NOTE: I would urge you to copy and not just transfer your emails, this will ensure that you have a copy of your emails in your original .PST file.

11. In some instances you may see the dialog box above. Depending on the size of your Outlook folders transfers could take seconds to hours.

Once the file transfers are completed you will have access to all of your e-mail from Outlook on Gmail.


  • Make sure your folder names do not use slashes (/) you will receive an error, there are other characters that I have not confirmed.
  • Unless you specify that your are copying the items over, the operation will move the files from your computer (the original.pst file) to Google’s servers and they will no longer be accessible from the ‘original’ .pst file. They will be accessible via Outlook but through the Gmail folder list.
  • It may seem that Outlook has locked up at times during the transfer, this is normal, it will happen if you have a lot of emails and/or large attachments, or your connection is slow.
