Shared Mailbox audit

Hello,

I am having trouble auditing a shared mailbox.  I have enabled auditing on a shared mailbox. When viewing the audit logs via the Compliance Manager the only audited event I have are from a user working in OWA. I do not see any events logged from any users using outlook.

 

 

Here is the status of the mailbox

 

PS C:\WINDOWS\system32> Get-Mailbox MAILBOXNAME | fl au*


AutoExpandingArchiveEnabled : False
AuditEnabled                : True
AuditLogAgeLimit            : 60.00:00:00
AuditAdmin                  : {Update, Move, MoveToDeletedItems, SoftDelete...}
AuditDelegate               : {Update, Move, MoveToDeletedItems, SoftDelete...}
AuditOwner                  : {Update, Move, MoveToDeletedItems, SoftDelete...}
