I just upgraded from NIS 2009 to 2010 and now this error message pops up whenever I send an email from Outlook 2007. The email shows up in the Sent Items folder but never actually gets delivered to the recipient. All the other accounts with this mail server are functioning properly. It seems to be a conflict with NIS and Outlook. Any ideas what this is about and how to fix it? I have other machines with Outlook 2007 and NIS 2010 that function fine.
Thanks,
Owen
