MSGraph Email Poller

Overview

Need to poll emails from your Exchange server? This smart service can be used in a poller process and extract the data from the Microsoft Exchange server. Messages are stored in the Appian Document System, as well as the attachments. Meta data is stored in a database table for further processing.

This plug-in provides an alternative to sending emails to an Appian process model when inbound email integration is requested. Instead of the email being forwarded to Appian, this plug-in reads the emails directly from the Exchange mailbox using the MS Graph API as described below:

  • Reads the mailbox(including digitally signed emails) using the MS Graph API
  • Convert the email to an EML file stored as an Appian document, with attachments removed from it
  • Store all email attachments as separate Appian documents
  • Store all email metadata (subject, author, recipients, etc...) into a set of tables in the database

Key Features & Functionality

  • All information how to deploy, configure and use the smart service is in the 'MS Graph Mail Poller.pdf' document in the downloaded zip.
  • Extract the files in the ZIP and follow the instructions in the document.
  • This plugin currently supports only MySQL and Oracle databases

    Any idea what it could be ?

  • in reply to jesusa583

    It cannot be downloaded anymore. However, if you open a support ticket, they can help you with a version compatible to the 22.1 version of Appian

  • Is it possible to download a version for Appian 21.3?
