although it worked correctly all day, a few minutes ago when I hit the send/receive button (in outlook) it says "cannot connect to server" with an error # of 0x800CCCOE How do I fix this please?

    0x800CCCOE error occurs when outlook cannot connect the mail server, this is usually caused by internet connection, incorrct IMAP/POP/SMTP server settings, atemporary mail server outage or the connection blocked by FW or security software.

    Hi jack fleming,

    I understand how frustrating it can be when Outlook suddenly stops sending or receiving emails. Error 0x800CCC0E usually means Outlook cannot connect to your email server.

    Please try the following:

    • Sign in to your email account through a web browser to check whether the service is working.
    • Close Outlook, restart your computer and internet router, then try Send/Receive All Folders again.
    • In classic Outlook, select File > Account Settings > Account Settings, choose the affected account, and select Repair.
    • If you recently changed your password, update the saved credentials in Outlook.
    • Verify that the incoming and outgoing server settings, ports, encryption method, and authentication details match those provided by your email provider.

    If the incident continues, please let us know:

    • Whether this is an Outlook.com/Hotmail, Gmail/Yahoo, Microsoft 365 business, or another email account.
    • Whether you can send and receive messages successfully through webmail.

    Thank you for your understanding.
