Re: Exchange Reporting.
If you want to track the user mailboxes, shared mailboxes and resource mailbox easily via HC panel then there is an option at host-admin level to create the custom Exchange report by navigating to this path: Reports >> Exchange Reports. From here you can add the given below custom Power-Shell command.
Get-Mailbox -RecipientTypeDetails SharedMailbox, UserMailbox, RoomMailbox,EquipmentMailbox
This will solve your problem.
