I have a simple workflow that is just meant to send an automatic notification email when a document is updated. It works fine when I put in specific users in the 'to' field of the email. However, the actual list of recipients is ~40 people, and in order to manage this I had created a SP group "Email recipients" and wanted to send the email to this group. When I do this, the workflow hangs (although it doesn't suspend), and I get the following error message:
Retrying last request. Next attempt scheduled after 04/04/2016 16:54.

It works fine for a smaller Sharepoint group (4 people)... I have no idea what could be causing this problem. Can anyone help?
