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:
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.
Hi, we have an issue when mail poller is trying to download an email with reasnably large (18Mb) attachments from Exchange folder - after a short time, the email gets moved to Expection folder without being processed. In the logs I can see the following error:
2024-04-12 11:33:23 WARNING [OkHttp ConnectionPool] okhttp3.internal.platform.Platform.log A connection to https://graph.microsoft.com/ was leaked. Did you forget to close a response body? To see where this was allocated, set the OkHttpClient logger level to FINE: Logger.getLogger(OkHttpClient.class.getName()).setLevel(Level.FINE);and then shortly after:
