You want to have mobile access to the mailboxes managed by the help desk or the departments via Active Sync. No administrative rights on the Exchange Server should be required. You therefore have the following requirements:
- Manage Active Sync for mobile access to email, calendar, contacts etc.
- Reset and delete data on mobile devices via Active Sync
- Secure delegation of this task to the help desk or department
- Exclusively for assigned mailboxes or users
- No administrative rights to Exchange Server required
