Message Trace Attachment Attribute missing
Message Trace do not include Attachment property and by only knowing attachment name you cannot find it. For example knowing a specific attachment has been leaked out from company but you cannot search it from the Trace.
Yes, it would be very helpful to have attachment details in message trace. Thanks.
