we are currently facing an issue where Campaign won't publish or send Transactional Messages when the Message contains a Link to a Landing Pages that is assigned to an Organizational Unit other than "All" (i.e. a custom OrgUnit).
The message icon in the log simply turns gray:
and the message itself won't display any error message in the log. As soon as the Landing Page is assigned to the "All" OrgUnit the message can be sent without any issues. The OrgUnit of the Transactional Message itself seems to have no significance.
Is that a known issue or is there any way to change this behavior?
