Issues migrating from Exchange 2013 to Google Mail and Calendar
Posted on 2016-11-08
We are in the process of migrating from our in-house Exchange 2013 server to Google Mail and Calendar. I've tried using 2 separate methods to do a test migration and neither is working.
The Google Apps Migration for Microsoft Exchange (GAMME) tool fails with an error message "Rerun migration. The GAMME retry limit is 10, but if the server was either heavily loaded or unreachable it will eventually exit. Admin must re-run the job to migrate pending emails." Super helpful message I know. I've also tried using the Data Migration Tool that is part of G Suite (the new brand name for Google Apps) and get the error "Authentication error. The username or password you entered is incorrect. Please verify."
Anyone run into this issue with a migration? How did you get it resolved?
