I'm back - I initially reported (06/23/08), " have begun to receive the error message, "Receiving' reported error (0x80040154): 'Unknown Error 8s80040154'. And I cannot receive e-mails into my Outlook 2007. n response to that post, Hal suggested to reboot and run "regsvr32 inetcomm.dll". That did not resolve the issue. When I inquired (on 06/26/08) whether I could re-install OL '07 over the current installation or did I need to uninstall the enitre office suite and reinstall? Russ Valentine [MVP -Outlook] responded, "I've never seen a single problem that reinstalling Outlook would solve. What makes you imagine you want to? You can certainly do it if you want to waste your time." So now my question is, if I am not to reinstall, what can I do to get my OL back up and running? Any help will be greatly appreciated. Sue
