TFS/VSTS does not consider the action of creating links or updating links or removing links as an update of the workitem. Therefore, TFS4JIRA Synchronizer will not be able to detect the changes. The links would be synced when there are any updates at the workitem such as field's value change. |

Links which point to issues/workitems outside the project in sync profile will not be created/updated, and there will be warning messages showing in Logs. |
