I have a simple list with one field I named ‘Recipient’. It is a name field that allows you to select other sharepoint users. The workflow has one action, send email that does a workflow lookup at the Recipient filed on the current item and returns the field as a semicolon delimited email address. When I create a new item and select myself as the recipient the email gets sent but if I select anyone else the workflow goes into suspend status with the following status:
It confirms what we suspected, when I select my name from the people picker it returns my email address. But if I select anyone else the email is blank. Only thing I see funny is when I’m in the people picker I don’t see any names in the ‘All Users’ bucket. I get them from the ‘Active Directory’ or ‘Organizations’ bucket. Don’t know if that means anything, we just started using sharepoint.
