Hello,

Trying to move attachments on outbound emails to the matching Task on Cases, however i'm getting the error "System.DmlException: Insert failed. First exception on row 0; first error: FIELD_INTEGRITY_EXCEPTION, Attachment owner must be the same as the owner of the parent task or event.: [OwnerId]"

My aim is to find the userId of the user who created the task, via ActivityID on the emailMessage object and use this when adding  a new attachment with the task as the owner.

The problem is that I can't find any reference to ActivityID when querying the task. Does anybody know how to related the ActivityID on the emailMessage object to the task. One would assume this would be the task Id but this does not seem to be the case?

Cheers

Code snipped- ------

Map<Id, EmailMessage> eMessage = new Map<Id, EmailMessage>([select id, ActivityId, ReplyToEmailMessageId, ParentId, (select Id from attachments) from EmailMessage where ParentId in:cIds]);
     
          
     
      for (EmailMessage a : eMessage.values()){
       system.debug (a.id);
       msgTest += a.id + ' ';
     
       if (a.attachments != null){
        for(attachment atc: a.attachments){
      attIds.add(atc.Id);
      system.debug ('attchment ID' + atc.Id);
     }
       }//if
      }//for


List<Attachment> attCopies = new List<Attachment>();

List<Attachment> Atts = [select Id, name, body, Parentid from Attachment where Id in:attIds];

for(attachment att: Atts)
{
  if (eMessage.get(att.parentID).ActivityId != null) {
       
   
   attachment copyAtt = new Attachment(name = att.Name, body = att.Body, ParentId = eMessage.get(att.parentID).ActivityId, ownerid = xxxxxx);
   system.debug ('this is the activity ID - attachment will be updated' + eMessage.get(att.parentID).ActivityId + ' for item email ID ' +  eMessage.get(att.parentID).ActivityId);
   
   attCopies.add(copyAtt);
   }   
}
