Workflow Engine not responding to Approve/Decline Emails

SmartActions functionality no longer works - responses to task notification emails are not getting processed by the K2 server – or at least it’d appear so. We verified the email are being sent out from the user mailbox.

Error Exception:

“61012 Exception from message source System.InvalidOperationException: There is an error in XML document (123, 13296). ---> System.InvalidOperationException: Instance validation error: 'OneOff' is not a valid value for MailboxTypeType.”


This error exception will occur on mailbox account that are set to "OneOff" mailbox type instead of normal "Mailbox" type.


This issue is isolated to a few Appit instances. If you happen to be one of the lucky few please reach out to K2 Support by logging a ticket request for a FIX.

This will be addressed when Appit 1.3 Update 3/Appit 1.4 ships.
