Task and Appointment Synchronisation with CRM Online and Office 365

Hi there

I have a CRM Online instance. I have set up a mailbox with server side synchronisation enabled.

It seems to be working, if I sent an email from CRM it works correctly, if a reply comes in I will see it.

My contacts have been synced to the office 365 account.

If I create a task or appointment in crm, that also gets synchronised to my office 365 account.

Does this synchronisation work the other way?  If I create a task or appointment in Office 365, it does not get synchronised into CRM (seemingly) at the moment.  Am I incorrectly assuming that this should be possible?  Is there a way for this to work?

Thanks in advance
