  • Hi, 

    when I use this plugin in mails that includes accent marks, the body doesn't show well:

    In the last version (before 22.3), this didn't happen. Anyone with the same bug?

    We updated our process model to use the new smart service node and are now receiving this error:

  • Release Notes - v2.0.0
    • Updated to support the jakarta mail library introduced in Appian 22.3
  • in reply to Venkatesh Suram

    We've been working with Appian to get them to update it.  Hopefully it'll be ready sooner than later.

  • Hello Everyone,

    We are also facing the same issue after upgrade to 22.3 version. Is there any update on the remove deprecate Java API and update to latest one?.

    Thanks!!

  • in reply to keitht

    This is caused by the Javax mail package change in 22.2, so the plugin will need to be updated: docs.appian.com/.../Appian_Release_Notes.html

  • Hello,

    We upgraded to 22.3 and are no longer able to use the Create Eml File functionality (smart service or expression).

  • Hi,

    Is it possible to retain the html tags of the email body? 

    I have a requirement where in I need to fetch the selected data out of the mail body. Is this plug-in a right fit for such requirement ?
