All mail on the Exchange server will be automatically migrated for you. However, if you were archiving or saving content locally through your previous client (eg. Outlook or Entourage), this page will provide instructions for you to import that content into your new account. Please wait at least 24 hours after your migration to import content.
Find your email client on the list below to see the best tool to migrate your locally saved mail data:
PC / Outlook- Google Apps Migration for Microsoft Outlook (recommended) or Google Apps Sync for Microsoft Outlook
Other Platforms / Clients - IMAP Drag/Drop
Other mail clients are NOT supported by the Gmail Uploader for PC. Trying to upload mail from these programs will not work. The Google Email Uploader for Mac OS will upload Eudora (Mac) mail archives as long as Eudora is installed in the default location on your mac (~/Eudora Folder). Eudora and Windows Mail are not supported by CIS.Eudora
Some people have had success migrating their Eudora mail into Thunderbird and then using the Google Email Uploader from the resulting Thunderbird mailbox. This is not supported by CIS but may be successful in some cases.
