Task Notifications not being sent

Hi itjwstl, 

Do you have HostServer logs from when the email should have sent? (These are typically located in [INSTALLDIR]K2Host Serverin) If so, are there any error messages in the logs? 

If there are no errors in the HostServer logs, are task notifications sending from other processes? If there are no other processes with task notifications, and there are no errors in the logs, can you check the EventBus.ClientRecorderError table in the K2 database and see if there are any entries that correspond with the time the task notifications should have sent?

Hi ltjwstl,

Out of curiosity, can you reset the Recipient to the Originator and see if the email will send out?

Hi ltjwastl,

After you have started the instance of the workflow was there any error shown in K2 Management ?

you may check in the below path

K2 Management site > Workflow Servers> Errors

If there are errors from that certain instance kindly click on details and attach the screenshot here

Cheers,

Kate

Hello,

looking through the log, this error is occurring each time the workflow is being executed

"270232168","20*personal details removed*:51:13","Error","MessageBus","61007","SendMessageException","MessageBusRuntime","61007 Permanent failure sending message : System.Exception: No destinations could send the message .

looking at the following knowledge article, I noted the values are not matching as suggested. the service account is not associated with the email account.

could this be the source of the issue?

sendmailfrom=*personal details removed*
<system self="K2:domaink2service" enableListeners="True" allowAmbiguity="true">

thank you for the suggestion, unfortunately this did not solve the issue

Hello,

Can you please confirm that you have the correct mail server set as 'Default' in the server's corresponding Environment Library?  Please see this KB https://help.k2.com/support-services/kbt171668.

Hi ltjwstl,

Could you share some details on the error that you saw in the Hostserver log? If the Send Task Notification starts in K2 then it will have the following events in the log, see sample below.
