Some longer time ago I was asked to think about a solution, allowing my client to notify his employes, about changes and news that were being published in the application built on SharePoint 2013. However, client did not want to use alerts, or to develop a dedicated application. No – the client wanted something like a newsletter, which would allow him to sent HTML formatted messages to all users (or SP Groups of users) who were working with the application, or to anyone having account in SharePoint (or to anyone beyond the organization).
Have you ever faced that issue? When your workflow is running smoothly and out of nowhere it gets suspended? Then when you hover the “i” icon to get more details you are informed, that “The workflow instance was too large to persist”? Well I had. Here is what I found and how I recommend to solve it.
