Smart action replies are not working and are not actioned on as expected. Worklist items on K2 Workspace are not updated or actioned.
After moving On-premises Exchange mailboxes to Exchange Online mailboxes, Smart actions are not working and are being picked up by the K2 Service mailbox as Spam and cannot be processed.
This was identified by applying debugging and the below errors were presented:
OnMessageReceived tmp SPAM!
To resolve this issue, add the entries below in the K2HostServer.exe.config, and restart the K2 Blackpearl service:
<system self="K2:Domain\ServiceAccount" enableListeners="true" allowAmbiguity="true">
<security spamSecurity="Off"> <!-- Default is InternalMail. -->
