"ObjectClass: Unknown" is returned when you use the Get-MailboxStatistics cmdlet


When you use the Get-MailboxStatistics Windows PowerShell cmdlet to get information about a mailbox in on-premises Exchange Server or Exchange Online in Office 365, the ObjectClass property unexpectedly returns a value of Unknown

For example, when you run the Get-MailboxStatistics admin | FL *object* command, you receive the following output:
ObjectClass : Unknown
ObjectState: Unchanged
In earlier versions of Exchange Server and in Exchange Online in Office 365, the ObjectClass property returns the correct value. For example, this property returns Mailbox for user mailboxes and Mailbox, Disabled for equipment and room mailboxes.


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
