I cannot get Outlook 2003 to receive e-mails. It seems to stick at 50% complete in the status bar and goes no further. To be fair it has been doing this on and off for a while, more so since installing the free Norton 360 from the last beta testing, but that usually corrected itself at the second attempt. This does not happen with the latest product; it simply refuses to go beyond 50% whatever I try and do.
At this stage I cannot say that NIS is to blame. It may just be a coincidence. When I have more time, I shall uninstall NIS 2013 and see if that solves it.
