Exchange 5.5 Monitoring/Auditing Tools

Does anyone know of/have experience w/ a product that is “intuitive” and “user-friendly” that meets the following requirements:
– Track/report Exchange obj./NT Domain account associations
– Extract Exchange account data from ALL available fields (tried several tools, but certain fields are always excluded — e.g. Supervisor field)
– Track/report permission changes on Exchange objects
– Track/log Exchange object deletions

Thanks in advance.
