If your simple SharePoint Designer workflow won’t start, look at this.

So I have been building some custom SharePoint Designer activities, and testing them on a Virtual Machine of mine. I log into that machine as the System Administrator, and of course browse SharePoint. I noticed that for even the most simplest workflow, while I could start it manually, it wouldn’t start automatically no matter what. I searched through the logs and found this:

“Declarative workflows cannot automatically start if the triggering action was performed by System Account. Canceling workflow auto-start.”

Well, there ya go. If you are logged in as the System Administrator, workflows won’t automatically kick off. Simple fix.
