I have a number of site workflows that run on a loop and notify users if items are due.
The workflows run on the same lists, and are nearly identical except the ones that have "Add Time to Date" with days or months subtracted from the date when action is executed (see screenshot attached) are immediately suspended with the following error. The other workflows run fine. I can't understand how "Add Time to Date" would affect the sending of e-mail messages?
Help?
