Send/Cancel Meeting Request and Generate iCalendar

Overview

Send and cancel a meeting request (iCal/vCal event) and generate the iCal String so that it can be written to a file.

This version is for Appian 22.3 and above. Cloud customers on a lower version of Appian that want to install this plugin should open a support case. Self-managed customers can find the latest jar for Appian 22.2 and lower version in the appmarket download file.

Key Features & Functionality

Contains three Smart Services that can

  • Generate an iCalendar String so that it can be written to a file
  • Send a Meeting Request (iCal/vCal event)
    • Returns the meeting unique identifier (uid) so that it can be used later to cancel the meeting request if needed
  • Cancel a Meeting Request (iCal/vCal event)
    • Given a uid returned by a previous execution of "Send Meeting Request", it allows you to cancel the meeting request and have it removed from the guests' calendar

A sample Appian application is included with the download of this Plug-in.  Release notes are also provided as part of the download package.

  • Hello all

    I am using the "Send meeting request" Smart service in the process model.

    The smart service was properly executed without any error but I am not getting any meeting email or Invite.

     

    In the System logs, I am getting the below exception.

    ERROR com.appiancorp.ical.Mail - Could not send mail via us-east-1.smtp-gateway.appian-customer.com:587 to com.sun.mail.smtp.SMTPSendFailedException: 530 5.7.0 Must issue a STARTTLS command first

  • Hi, iCal string and meeting uuid has been generated. But how can we integrate that event with outlook . Can anyone elaborate the use case of this plugin ?

  • Hi everyone, 

    I am facing an issue with this smart service. It doesn't work. In the process model monitoring, the node is completed, but it doesn't send any meeting. 

    Can anyone help me?
    Thanks

  • Hi,

    we are testing the plugin on Appian Community Edition 22.3 and we are facing a similar issue as Simone, the log reports:

    ERROR com.appiancorp.ical.Mail - Could not send mail via eu-central-1.smtp-gateway.appian-customer.com:587 to 
com.sun.mail.smtp.SMTPSendFailedException: 530 5.7.0 Must issue a STARTTLS command first

    Is there a solution?

  • While executing the plugin in Appian, the Process instance was completed but the plugin is not getting initiated . I think a java library is missing and waiting for you to update. Kindly accept my request and look for the update

  • Release Notes - v5.0.0
    • Updated to support the jakarta mail library introduced in Appian 22.3

  • Will this plug-in be affected by Appian's transition to Jakarta Mail from Java Mail?
