**Mac Mail only provides basic Exchange Support and will not provide full functionality for the Hosted Exchange Environment as it cannot synchronise; Calendars, Contacts, Tasks or Rules.
While we can support the software a lot of the fundamental content of Hosted Exchange is not accessible via Mac Mail and as such we would always advise the use of Microsoft Outlook 2011 for Mac in the first instance**
