Last night’s batch of users, including all of Raymond Hall, was the largest single group we have migrated so far. Users’ mail is still being copied as of this writing. Please be patient and give the process some more time to complete.
Be advised that the process is NON-DESTRUCTIVE, and that all of your pre-migration e-mail still exists on our old server where you can still reference it via Apple Mail, Thunderbird, BearMail, or SOGo. If you need to reference e-mail that has not yet made its way into Office 365, you can find it there in the meantime.
