I have just installed NOD32 throughout the company (40+machines). No problems so far, except one.... One client has problems receiving email from our Exchange server, we use NT4SP6 with Exchange Server V5.5SP4 and use Outlook2k clients on Win2kProSP4 machines. Basically, in order for this one user to see if they've had email, they either close and restart Outlook or click any other folder other than Inbox. I have stripped and removed Office completely - still the same. Just removed Nod32 and the email client works perfectly, put it back in and the problem is back. I have disabled NOD via it's control panel and the problem is still there. All users hae the client installed via login script and all have the same config.. Any Ideas please?
