error message 603 e-mail scanning is not functioning due to a severe error

I am regularly getting this message when I boot up my pc and before I have opened Outlook. Has anyone come across this before and if so what does it mean and what should I do?

    Please clarify as to which F-Secure product, operating system and Outlook version is used here.

    Do also note, the E-mail and Web Protection board is for discussing gateway level web filtering solutions.


    To check the F-Secure version, right-click the F-Icon and select About.

    What are doing on your computer when getting the error message?


    Do you have a reliable way to reproduce the error?


    One question are you connection on SSL to your mail server, encrypted mail traffic can not be scanned and will cause an error.

    Hi jl,

    Please find out which e-mail protocol in used?
    - Open Outlook 2007 > Tools > Options > Account Settings.
    - Email Accounts > Select your account > Change > More Settings > Advanced tab.
    - Look for
    a. Incoming server port number, does it use encrypted connection?
    b. Outgoing server port number, does it use encrypted connection?


    Best Regards,

  • I am also getting this error on bootup, before user even logs into system. Win XP SP3, all updates current; Outlook 2003 SP3. POP3 port 995, SMTP port 465, both with SSL enabled. However, to reitereate:L this error appears before use even logs into Windows, at which point Outlook is not even started!
