For Mail Basic and Mail Business Accounts
Learn how to migrate the email messages from your old 1&1 IONOS Mail Basic or 1&1 IONOS Mail Business accounts to your recreated accounts after you've completed an internal domain transfer.
Your email accounts do not move with your domain when you move the domain from a package, such as with an internal domain transfer between packages. Instead, the email accounts associated with the transferred domain are renamed with a new domain since the domain they were originally created with is no longer available. This helps to ensure that your messages are not accidentally deleted by moving the domain.
The email accounts will be renamed with the ending email@example.com and the original @ symbol will be changed to an underscore (_). For example, an email address originally named firstname.lastname@example.org will be renamed to email@example.com.
There is a 25-character limit for the renamed backup mailbox. For example, firstname.lastname@example.org would be renamed as email@example.com since "jonathansmith_verylongexa" is the maximum 25 characters.
You will need to recreate the original email address (in our example, firstname.lastname@example.org) in the package that the domain was transferred to and then import the emails from the email@example.com address (in our example, firstname.lastname@example.org) to the recreated email address in the Webmail interface using the steps below.
Log in to 1&1 IONOS Webmail.
Click the Add Mail Account link in the Mail tab.
Click the Manual button.
In the Account Settings section, enter an Account name (used to describe the account), Your name, and the email@example.com address you are migrating.
Scroll down to the Incoming Server section and choose/enter the following information:
|Username||The firstname.lastname@example.org address entered in Step 4|
|Password||The password previously used for the mailbox|
Scroll down to the Outgoing server (SMTP) section and choose/enter the following information:
|Authentication||As incoming mail server|
Click the arrow (A) next to the newly-added account and click on its Inbox (or other folder containing messages you would like to migrate).
Either check the box Select all (B) or click on a message you want to move. Now you can drag emails (C) from here to the Inbox located at the top-left of the page. This will move the emails from the old (backup) email account to the Inbox for this email account.
Your new email account will now contain all of the messages you migrated. If you find that any messages were missed during this migration, you will still be able to access them and repeat this process as long as you do not deleted the email@example.com mailbox or cancel the package it is contained in.
