Hi [mention:7fe03aa321af4cadbca97d8d1fc1a492:e9ed411860ed4f2ba0265705b8793d05]

We’ve been using this plugin for a while, and recently noticed some issues while processing emails related to the charset (see error below). The main problem is that when an error occurs, the smart service doesn’t return any error message, and there’s no option to mark the email as unread on failure. This makes it difficult to identify which emails failed to process. Ideally, we’d expect the error details to be included in the error message or have the email marked as unread when a failure occurs. At the very least, if we can capture the error message, we can set up alerts and better understand what’s happening.

I want to know the values of two parameter
1.Java Mail Keys
2.Java Mail Values

"mail.imaps.connectiontimeout " is this correct?

Hi [mention:7fe03aa321af4cadbca97d8d1fc1a492:e9ed411860ed4f2ba0265705b8793d05] Does this plugin support self signed certificates? We have some issues after changing server certificates to self signed certificates

We are on 25.2 and this plugin is working fine till last week. but we are receiving the below message adhoc and even though we configure the time limit for 3 minutes the log says its polling and reading the data for 30-46 minutes in the background. No changes to code. Any thoughts to troubleshoot

"The amount of time allocated for the completion of an unattended activity was insufficient to allow the activity to complete"

We suspect the plugin is incompatible with recent updates in Appian's runtime environment.

Hi,

We are facing an issue with the Mail Poller plugin after upgrading to Appian 25.2. The plugin is no longer working, and our email poller process model is failing.

We suspect this is due to the version upgrade, as it was working fine before. Has anyone else experienced a similar issue with this plugin after upgrading to 25.2?

Appreciate any help or suggestions.

Thanks

Hi,
We are facing an issue with the Email Poller plugin. Specifically, email attachments (Doc Type: PDF) sent from a particular email ID are not being read correctly on the Appian end. However, emails sent from other email IDs are working fine.

We have verified the EML file, and the documents are present. Unfortunately, we have been unable to find a solution to this issue. Please help us resolve it.

Thanks in advance.

Hi,

We have recently been experiencing cases where emails are moved to the "Exceptions" folder, but metadata is still written to the database. On other cases, email messages are moved to the "Exceptions" folder but on moving them back into to the Inbox folder, get successfully polled in.

Is there an explanation for the behavior we are experiencing and how can we fix it?

Thanks,

Hello,

we are currently using version 1.1.7 on Appian 21.3.

Mail Poller does not recognize attachments for a specific email address. The email itself is stored normally, but the attachment is nowhere to be found. According to the email exchange team, they don't see an issue with this email address or the attachment.

Is there any way to find out what the issue might be? Which email property does mail poller access to find attachments?

"X-MS-HASATTACH: yes" is present in the header.

Thank you in advance.
