EAC logging only logs commands when the EAC logging window is open and it is not enabled on by default.
Exchange Online Protection offers some great compliance functionality in the cloud such as real-time DLP policy and rule matching. Adding these reporting features would be a great addition to the On-Premises product and helpful for validating localized transport of email containing PCI or PII data.
In Exchange 2013, there are many options available when running a search cmdlet in PowerShell in particular to target those results to a Discovery Mailbox of your choice (i.e. New-MailboxSearch -TargetMailbox), but this option does not exist in the Exchange Admin Center. Allowing these options in the EAC will be helpful for non Exchange Admins, such as Compliance Officers to perform their daily tasks.
It would be great to have a way to centrally manage the CMDlet Extention Agents instead of per server.
Aditionally preserving them through a CU upgrade would be equally appreciated!
