    Every day we can find some discarded messages and we are not be able to trace the message with the command get-messagetrackinglog. It seems that the message is discarded and deleted and we can't find trace of it...

  • Hi Emilio_José,

    To narrow down this issue, I want to confirm with you:

    1. When this issue occur and whether this issue occur on all mails that send from this users?

    2. Whether this sender receive NDR about this issue?

    You can also try to recreate Sender connector.

    Regards,
