Hi Rick，
To understand the issue better, I’d like to confirm the following things:
1. What Office 365 plan are you using?
Office 365 Home Premium is an consumer product which just includes the Office software such as Word, Excel and Outlook, and it doesn’t include the Exchange Online service.
2. When you say “single user setup of Office 365 Exchange Online”, do you mean you have bought a standalone Exchange Online, Office 365 Small Business or Office 365 Enterprise?
3. Do you have an Exchange local Server by “Personal Exchange Server”?
4. “ I've managed to sync my exchange account (email, contacts, and calendar) with the local version of Outlook Mac 2011 (on the Macbook) “exchange account” “, do you mean the Office 365 account set up on Outlook 2011?
5. What does the sync services mean?
6. How many email accounts do you use?
7. Could you please take an example to describe your situation and goal you want to achive?
Thanks,
Vivian Wang
