We have had a migration from SharePoint 2013 to SharePoint 2016. We are using email enabled lists in our environment. Since the migration workflows do not start anymore when items are created by mail. This behavior was not the case in SharePoint 2013 last week. Has anyone seen equal behavior in his farm?
Workflow in the lists start as expected when creating new items "by hand". But when items are created by mail the workflow does not start.
Anyone any suggestions how to get by this problem?
