Individual users can use the mailbox migration tool within the webmail interface to import existing email and collaboration data from most third-party mail servers.
Follow these steps to use the mailbox migration tool:
NOTE: The mailbox migration tool will only transfer email, contacts, calendars, tasks, and notes (if supported) from a single third-party mailbox to your SmarterMail mailbox. System administrators can use mail server conversion tools to migrate multiple mailboxes or entire domains from mail server applications like MailEnable, Merak, MailMax, or Imail quickly and easily. System administrators can also use Web services to run migrations for multiple accounts.
