I just upgraded from NIS 2009 to NIS 2010 (v 17.7.0.12). I know this issue was addressed and solved last September (2009) for Outlook 2003, and I tried the same suggestion given, without success for Outlook Express 6 [deactivated AntiSpam in NIS settings and then reactivated it again afterward]. I, too, checked the "Don't show this again" box, which has no effect either.
I never encountered this "Welcome" box in NIS 2009, and find it really annoying! If someone has found a permanent solution, I look forward to reading it here. Many thanks in advance!
Hi Phil_D -- thank you for your welcome! Hallelujah!! Your solution worked, and it was so obvious . . . I never even saw this option. Many, many thanks!
