My organization is in the process of switching to Google Apps for Education. I have successfully used Google Email Uploader to migrate my emails (as an admin of the domain). However, when I attempt to upload another users email, I encounter the following error:
Username or password not accepted
This domain does not allow users to access the Email Migration API.
Error 403
API Access has been enabled in the User Settings for our domain. Does this take some time to activate? Are there other steps I must take prior to migration? Thanks.
