Description

A mailbox can have hidden items that are never visible to the user and are only used by applications. The Get-EXOMailboxFolderStatistics cmdlet can return hidden items for the following values: FolderSize, FolderAndSubfolderSize, ItemsInFolder and ItemsInFolderAndSubfolders.

Don't confuse Get-EXOMailboxFolderStatistics cmdlet (folders) with the Get-EXOMailboxStatistics cmdlet (mailboxes).

This example returns statistics only for calendar folders.

Example 3

Get-EXOMailbox -ResultSize Unlimited | Get-EXOMailboxFolderStatistics -FolderScope Inbox | Format-Table Identity,ItemsInFolderAndSubfolders,FolderAndSubfolderSize -AutoSize

This example uses the FolderScope parameter to view Inbox folder statistics for all mailboxes.
