    Tried this and all sorts of other methods found on the internet. Outgoing mail is still "stuck" in the Outbox. Don't understand why it went from working property to all of a sudden being stuck. i didn't do anything differently.

    Hello Diane,
    I have been working on this issue for 2 weeks. I have done all fixes I can find on Microsoft's website along with your suggestions. I have restarted my computer endless number of times after trying each fix. The error codes are: 0x800CCC0F and 0x800CCC90. There are 3rd party fixes I have found online, though I have avoided using them thinking this could be further trouble. Can you please point me to the fix for this. I am really tired of this and this is an Outlook 2010 problem that may be to be related to an auto update. Please advise.

      Was an update installed about the time the problem started? If so, which one?

    Hello Diane,

    I am getting the error code:
    Sending reported error (0x800CCC80): 'None of the authentication methods suported by this client are supported by your server.'

    I am getting this error since I updated QuickHeal Antivirus 2013. I disabled-uninstalled and then installed QuickHeal 2014, but the problem could not be resolved at any point of time.

    Using the "Repair" button and toggling the check mark on "My outgoing server (SMTP) requires authentication" is of no help either. Please assist.

    Task 'SSINHAROY@SCIGENIN.COM - Receiving' reported error (0x80042108) : 'Outlook cannot connect to your incoming (POP3) e-mail server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).'

    But all setting are correct

      That error is most common when antivirus software is scanning email. Does it work in safe mode?

    My outlook e-mails get stuck in the outbox only with certain wireless networks? If I create a hotspot with my mobile they all fly out no problem! Why is this?
