I've setup our Exchange 2013 in hybrid mode with Office 365. I'm able to migrate mailboxes to Office 365 just fine and I can create new mailboxes from the Exchange 2013 ECP by choosing "Office 365 mailbox" just fine, but my co-worker who already has rights to create mailboxes does not see the option to create Office 365 mailboxes.
My user account is part of the domain admins group, my co-worker does not have those permissions.
What permissions or roles are we missing?
Carlton.
