Calendar Sharing Exchange 2010
Posted on 2014-03-14
We are using Exchange 2010.
We want to be able to access calendar only on an iPhone client; but our security policy does not allow us to enable full ActiveSync access.
Our remote email access is via TMG.
I had an idea to create an Office 365 account and to share the calendar with this account; then to access the Office 365 account from the iPhone.
I set up federated trust for our domain successfully.
I then set up an Organization Relationship to allow free/busy access with time, plus subject and location, allowing a specific security group and a specific domain (the Office 365 account).
I then configured a Sharing Policy (not sure if I needed to do this - specifying the Office 365 domain and Calendar sharing with free/busy information plus subject, location and body) and applied to the specific mailbox.
When I go to OWA 2010 (as my desktop uses Outlook 2007) I can share my calendar with the Office 365 address - this appears as a Reviewer for the Calendar.
However from the Office 365 account, the calendar appears in the list but is empty of any information.
As I'm not receiving any errors in the setup I'm not sure if I've set this up correctly or if my firewall or TMG might be blocking this - or if it's not possible.
Any help gratefully received, thank you
