Miruna,

The issue does have something to do with the contents of the folder in Laserfiche. I made a copy of the workflow that just emails the contents of the folder that was created by the previous workflow that errored at the email stage. The new workflow is generating the same error message. I've copied the details above. Does Laserfiche Workflow have known issues with emailing folder contents that have more than one level of subfolders?

Thanks,

Mary
