Using the IONOS Email Migration Tool

In this article, you will learn how to move the emails and folders of an IONOS email account to another using the IONOS Email Migration Tool powered by audriga. This may be helpful/necessary, for example, if you want to use your email accounts with a domain in another IONOS contract within your account or another account altogether. You can migrate the following data:

• Emails and folders using IMAP or POP3
• Emails and folders, contacts, calendars and tasks from Open-Xchange and Microsoft Exchange

Depending on the type of email account (Standard, OpenXchange, Microsoft Exchange), you may also be able to migrate additional data, such as contacts or calendar entries.

You won't need to install any special software. The IONOS Email Migration Tool powered by audriga connects using the same protocols as an email program and copies your emails from account to account.

After Transferring a Domain to Another IONOS Contract or Account

When you transfer a domain, all email addresses that you have set up for that domain are deleted. However, in order to prevent unintentional data loss, the mailboxes with all of the emails in them remain in place.

To ensure that you continue to have access to your mailboxes, they are assigned a backup address in the following format:

old_address.com_0@mailboxbackup.info

If the domain ionoshelp.com is deleted, for example:

• The address mail@ionoshelp.com will be renamed to mail_ionoshelp.com_0@mailboxbackup.info

• The address john@ionoshelp.com will be renamed to john_ionoshelp.com_0@mailboxbackup.info

• And so on

If the email address has more than 25 characters, it will be shortened to 25 characters when the backup addresses are created.

To move the emails and folders of an email account using the IONOS Email Migration Tool powered by audriga, simply follow these steps:

• Set up an email account in the contract containing the transferred domain for each mailbox being migrated.

• Check how much disk space the source mailbox is using. If this exceeds the size of the newly created accounts, the migration will fail. If this is the case, you can simply upgrade the new accounts to a type with as much or more storage space.

• Follow the steps below called Starting the Email Migration.

Moving Emails and Folders Between IONOS Email Accounts

To use the Email Migration Tool, you must set up a destination (receiving) mailbox for each source (sending) mailbox. You also need the login details for the source and destination mailboxes.

We recommend that you assign temporary passwords for your mailboxes and use them during the migration.

Before moving, check how much space is being used in the source mailbox. This must not exceed the size of the newly created target mailbox.
