EWS Migration to Graph Error

We recently migrated a K2 5.9 FP14 system from EWS Online to Graph and noticed issues with mails.

The mails for tasks and redirects are not going through but email action ones are, has anyone had a similar issue with Graph and found a solution?

We checked the HostServer and Event View logs, but no errors are showing up.

Hi ​@StevenK1,

Thanks for sharing this. We believe the issue you’re describing with task and redirect emails after migrating from EWS to Microsoft Graph is addressed in K2 5.9 Fix Pack 15.
 


Could you please upgrade the environment to FP15 and test the task and redirect email scenarios again?
 

If the issue still occurs after upgrading, please log a Support ticket with some additional details around the affected workflows and email scenarios. That will allow us to investigate the specific behaviour further.
 

Thanks!
Tiaan
