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:

Could you share the Tomcat error stack trace?
I've tried this workaround but didn't works.Appian release 25.2Plugin ver. 4.2.10
MejulLawrence Have you solved?Megha Narayanan Any other suggestions? Thanks!
If you're using Appian 25.2, there's a known library incompatibility that's resolved in the latest version. You can also try the following steps:
Remove the plugin from the Admin Console.
Reinstall the plugin.
Delete and recreate the smart service
Hi Community,
We’re facing an issue with the MS Graph Mail Poller smart service in Appian. When the process executes, it fails with the error:
An error occurred in executing an Activity Class Node Name: MS Graph Mail Poller
We've confirmed the connected system credentials are correct, and the token is valid. However, the node consistently fails without detailed explanation.
Things we've already checked:
Input parameters like mailbox/folder are populated correctly.
Connected System connection test is successful.
Plugin version might be outdated(Current version - 4.2.6) , but we’re unsure if that’s the root cause.
No custom error message or stack trace from the node itself — just a generic execution error.
Has anyone else encountered this issue? Is this likely due to plugin incompatibility, or is there a specific known limitation or fix for this error?
Any guidance or troubleshooting steps would be appreciated.
Thanks in advance!
Hello, we are trying to use "MSGraph Email Poller" for the first time, configured all the attributes in admin console and process model, however, seeing the below error. Anyone has faced before during initial setup?
Error code: ErrorInvalidUser Error message: The requested user 'abc@xyz.com' is invalid. GET https://graph.microsoft.com//v1.0/users/abc@xyz.com/mailFolders/deleteditems SdkVersion : graph-java/v5.80.0 404 : [...] [Some information was truncated for brevity, enable debug logging for more details]
BCC columns will not be populated as they are hidden by the mail server on purpose. The only time you could populate them is if you are sending an email and preserving details.
Honestly, not sure why we have these columns in a mail poller.
