Hello!
I can't enable mailbox audit logs. I use cmdlet Set-Mailbox -Identity "mailbox" -AuditEnabled $true and Get-Mailbox shows that audit is enabled. But when i check Get-Mailbox| Get-MailboxFoldersStatistics there is no "Audit" subfolder, and all audit searches also return no results.
I am working now with several Exchange installations (five actually, and one is brand-new test lab) and checked the same in each organization. Result was the same!
I am stronly sure i miss something important, could you point it to me?
