POP email typically stores messages locally on a computer and removes them from the mail server after a client downloads them. In many cases, you can’t migrate this data with our migration tool when it does not exist on your source mail server. This article walks you through performing a manual migration of POP data by using Outlook® to a Rackspace Email account via IMAP.
You accomplish this task by adding your new Rackspace Email IMAP account to the same profile that your POP account is on. This change enables you to move all of the locally stored email messages to your new Rackspace Email account.
To learn more about the differences between POP and IMAP, see IMAP and POP mail protocol comparison.
Before performing the steps, ensure that you have already created mailboxes on the Rackspace environment and updated the MX records so that email routes correctly to Rackspace.
For increased security, we recommend that you use our secure (SSL) servers. If your internal system configurations require non-SSL ports, those settings are available in the previously referenced article, IMAP and POP mail protocol comparison.
In Outlook, navigate to Account Settings. For example, in Outlook 2013/2016, go to File > Account Settings > Account Settings.
To add your IMAP account, click New.
Enter your name and email address,
IMAPfor the account type,
secure.emailsrvr.comfor the incoming and outgoing mail servers, and your user name and password.
Select the Remember Password check box if you don’t want to type your password each time you launch Outlook.
Click More Settings.
Click the Outgoing Server tab.
Select the My Outgoing Server (SMTP) Requires Authentication check box.
Leave the default setting, Use Same Settings as My Incoming Mail Server.
Click the Advanced tab.
Set the incoming port to
993and the outgoing port to
465, and enable SSL encryption.
Navigate to your Inbox. Your new IMAP account link displays in the left folder pane. Click on the account to expand the folders. You should see mail items for that account start to appear.
Now that you have added your Rackspace account via IMAP, you can drag emails from your POP inbox to your IMAP inbox. As items start moving over, those emails automatically upload to our server and are visible across all of your devices connected via IMAP to that account.
NOTE: Depending on the number of emails in your POP account, this process can take a while. You can also consider moving emails over in batches by selecting groups of email messages. After you’ve confirmed that all emails have moved to the new account, you can remove the configuration for the POP account because you no longer need it.
After the change, your email looks similar to the following screenshot.
