Support for custom contact/task fields and for "other peoples calendar" in Exchange

Does eM client support custom contact/task fields in Exchange (created using Outlook). We have added a number of custom fields both to some of our address lists and to some of our tasklists.

Is it possible to open other people’s Exchange calendar? I can add other user’s accounts via “Delegation”, but that not only adds their calendar, but also their entire mailbox. I only want to see their calendar.

Thanks for your reply.
