Due to the many gigabytes of email saved on server NC018, the migration is still ongoing.
We are disabling domains on server NC018 as they are migrated to server NC027. What this means to you is that, if you find that you can no longer access your email account, it has probably been transferred and you should start using the settings for server NC027. Please see the “Things you need to do” heading in the Email migration: Update 1 post for that information.
Thanks for your patience.
