  • Lists all user display name and mailbox size in KB for individual database:  

 

Example database name in below script is DB02.

$_.DisplayName.ToString()+" "+ ($_.TotalItemSize.Value.ToKB()+$_.TotalDeletedItemSize.Value.ToKB())

}

$_.DisplayName.ToString()+" "+ ($_.TotalItemSize.Value.ToKB()+$_.TotalDeletedItemSize.Value.ToKB())
