GAMME system requirements
This feature is not available in the legacy free edition of Google Apps.
Google Apps Migration for Microsoft® Exchange (GAMME) is a utility that migrates mail, calendar, and contact data from your Exchange Server or mail from an IMAP server to Google Apps. You must meet the following system requirements before using GAMME.
GAMME currently doesn't work with 64-bit versions of Outlook.
We recommend that you use the latest patches for both Windows and Outlook.
For complete instructions on using GAMME, see the GAMME Admin Guide (PDF).
