Introduction: POP3 vs. IMAP – Read This First!

You can configure a G Suite / Gmail account in in Outlook using one of two methods of connecting to the server, called POP3 and IMAP. Each method has unique features, so it’s important to select the right method for how you typically use your e-mail. The lists below outline the differences between the two methods.



  • POP3 is the “one-way” method of downloading your e-mails from the e-mail server. Outlook will check the server for new mail, make a copy of any new messages, and download these copies to your computer. This means:
    • If you delete an e-mail message from Outlook, or move the message to another folder, the original e-mail remains in your inbox on the server.
    • If you use multiple devices to access your e-mail, the e-mail messages you send / delete on one device will not be sent or deleted on your other devices.



  • Like POP3, accounts set up using IMAP check the mail server for new messages and download copies of these new messages to Outlook. However, IMAP also sends information from Outlook back to the e-mail server. For example, if you create a new mail folder in Outlook, the same folder will be created on the e-mail server, and any e-mails you send from Outlook will also be accessible from the “Sent” folder on the server.
    • For this reason, IMAP is a much better choice if you access your e-mail from multiple devices, as any changes made on one device will be communicated to the server, and other devices be updated to reflect these changes.

In general, it is important to note that POP3 and IMAP accounts are not compatible with each other. That is, e-mail messages that were downloaded using POP3 cannot be moved into a folder belonging to an IMAP account and vice versa.

          1. This means that the username and password you have entered are not correct. Double-check the following information:
            1. Your username is your FULL e-mail address, e.g.,
            2. Your password is the password you use to log on to Gmail in your web browser — this may be different than the password you used for your Faster Solutions e-mail.


        1. E2: Error Message: “Send test e-mail message: Your server does not support the connection encryption type you have specified. Try changing the encryption method. Contact your mail server administrator or Internet service provider (ISP) for additional assistance.”
          1. This means that you may have selected the wrong encryption type for the Outgoing Server, or may have entered the server port number incorrectly. See Step #2.7 and #2.7B and ensure the information you entered matches these settings.


        • E3: Error Message: “Log onto incoming mail server (IMAP): The connection to the server was interrupted. If this problem continues, contact your server administrator or Internet service provider (ISP).”
          • This typically means that you need to double-check the settings of your Gmail account as described in steps #1.1 – #1.5 above. This same error message can also occur due to an incorrect username / password as described in E1. If you continue to receive this error message after double-checking the settings of your Gmail account, please contact Faster Solutions at


        • E4: Error Message: “Log onto incoming mail server (IMAP): The connection to the server failed.”
          1. This typically means that the incoming mail server address was not entered correctly. Review the information in step #2.6B and confirm that the information you entered matches exactly. It may also indicate an issue with your internet connection itself.
