How can I get the Mail ID from an email?

You can use the following script in a Javascript Task.

  2. require("validation.js");

  4. task.parameters = {
  5.     MailVariable: {
  6.         description: "The variable containing IMailInfo mail item.",
  7.         category: "Settings",
  8.         type: { id: "variable", variableTypes: "object" },
  9.         order: 1,
  10.         validate: validation.required
  11.     },
  12.     MailIDVariable: {
  13.         description: "The variable that will receive the MailId.",
  14.         category: "Settings",
  15.         type: { id: "variable", variableTypes: "string" },
  16.         order: 2,
  17.         validate: validation.required
  18.     }
  19. };

  21. task.run = function () {
  22.     var mi = this.variables[this.parameters.MailVariable.value].value;
  23.     this.variables[this.parameters.MailIDVariable.value].value = mi.ID;
  24. };
Pass in a variable of type object with your mail item.
Get back the ID for the mail item in the variable of type string you specify in MailIDVariable.
