Greetings:

I'm using Nintex workflow on SharePoint 2010 and find that I get an error when trying to CC members of a group, specified through a Person/Group workflow variable. However, I can send the notification using that same variable in the To field. Also, I can send to that same group if specified directly in the cc field instead of using a variable. It appears that Nintex (or SharePoint) cannot lookup the addresses of group members in the CC field when specified as a variable.

The error I get when using the CC field with a Person/Group variable is something like:

Failed to send notification. Cannot get the full name or e-mail address of user "521".

Is this a known issue? 

Thanks,

Bruce
