Automatically Deleting Jira Issues

Question: Can deleting a task in MS Project automatically delete the linked Jira issue?

Answer: No, it is not possible to automatically delete a Jira issue when the corresponding task is deleted in MS Project. This limitation exists because there is no reliable way to track task deletions in MS Project. However, the reverse — deleting a task in MS Project when the linked Jira issue is deleted — is supported by enabling the corresponding option in the Options tab of the Project Settings dialog.
