issues relaying to 365 for one user
admiral_sulu : You might have already checked this but just to confirm, this new user was provisioned on-premises and then migrated to office 365? or a remote mailbox was created directly in office 365. Check if remote routing address is properly stamped against the user. Another good test would be if you have any mailbox on-premises or you can create one, see if you are even able to send emails to the new user from your exchange server.
that seems correct
I have created mailboxes since then and no problems have been reported.
create the mailbox on exchange, then migrate to 365.
admiral_sulu : Yup, the remote routing address is of the format: user@mail.onmicrosoft.com, you should see that in your email address policy/ proxy addresses of users you migrated.
Going forth, you can either create the mailbox on exchange and migrate it or simply use the following command to create the mailbox directly in cloud :
Enable-RemoteMailbox "Kim Akers" -RemoteRoutingAddress "kima@contoso.mail.onmicrosoft.com"
This has same effect as migrated user.

Just to confirm, the issue has been resolved and you dont need any further assistance on this one?
