    All my installs are standalone. No FortiGate at all. I first Shutdown FortiClient using tray icon right click. Checked for incoming e-mails. It worked in my case. So I run FortiClient diagnostic tool on that system. That took about 5-10 minutes to complete. I then re-run FortiClient doing nothing in configuration files and no rebooting the system. Checked for incoming e-mails. It worked in my case (I just couldn' t understand what fixed the problem at all) I then rebooted the system. No change on config files, again. I checked if Outlook is ok. It was OK. I then shutdown the computer, waited some minutes. Re-open it. Try to see if Outlook is working, yes it is working. Several trials on reboot and shutdown/re-open, nothing unusual now. So, I am not sure, only logical explanation I can think of is FortiClient Diagnostic Tool is automatically fixing some very basic errors in config files. That computer has no problem now. Btw, I checked registry for key given above by ducachris, no such key was present in that system. Not even close.

    Today I am informed that Outlook cannot receive e-mails, again. Seems like what happened is temprorary. If I find more, I will post here. Will it be of help if I send FortiClient Diagnostic tool compressed file to support e-mail?

    If not using the Web Filtering feature, consider disabling Proxy from the settings page. Otherwise, report a new issue through Fortinet support.

    I am using web filtering. So, I believe, I will report this issue since it seems to be happening more than one computers. Is it required to send FortiClient Diagnostic report attached as reporting an issue?

    FortiClient Diagnostic report is not required, but is very useful.

    Hi theputter, thank you to share your experience with us! That was definitely my issue. Like you said after disabling the proxy on the forticlient everything works fine. I had used your first suggestion: 1. Disable the proxying all together within the Forticlient. Settings-->Disable Proxy Thanks again!

    If you only needs the VPN, you can disable the proxy. But if you need the Anti-virus and Web Filtering. For outlook and live mail just enable the Pop3s or encrypted Pop3 using port 995 from Properties > Advanced.

    FYI I ran into this same issue awhile back.

     

    https://forum.fortinet.com/tm.aspx?m=113423

     

    We've since moved on from using the POP3 server so obviously we don't have the issue but I will say I remember seeing some improper AUTH strings from the client in my POP3 logs on the server. When you disable the Forticlient proxy the client would communicate with the server properly. It was something that happened out of the blue after running Forticlient for quite some time so it had to be something that was updated at some point.

     

    Now I have a new issue where the Trusteer Rapport security plugin that several banks require is somehow conflicting with Forticlient causing continual blue screens.

     

    Good luck!
