Office 365 has been available for quite some time and there have also been two exams available:
70-321 Deploying Office 365
70-323 Administering Office 365
These exams focussed on larger enterprises and features corresponding with this use. More information about these exams can be found in my previous blog post. Keep in mind however that Office 365 is an ever evolving service and that things might have been changed since I wrote this blog post. Even Microsoft has retired and replaced some of their learning content.
Recently a third exam became available that focusses on smaller businesses 74-324 Administering Office 365 for Small Businesses. At the end of August a Jump Start event was held and now the recordings of this event have been made available on Technet Video.
I hope this is useful to you and that it will help you leverage Office 365 better.
