My SharePoint 2013 workflow keeps suspending itself at the point it's supposed to send an email. The email details have been specified in Central Admin but it's still not working. When the workflow is supposed to send an email out (internally) it suspends with an error. Here is the information that is given about the suspension.
RequestorId: 951f4793-1f5b-7054-0000-000000000000.
Details: An unhandled exception occurred during the execution of the workflow instance.

Can anyone tell me what could be causing this? I'm not 100% on what this error even means.
