    Este error sucede tambien con outlook 2007, 2010 y 2013.
    Después de aplicar el último CU11 de diciembre de 2015 a exchange 2013 en un DAG de 2 servidores, uno de ellos no ha arrancado correctamente y teniamos muchos problemas.
    Los sintomas son los descritos en este artículo y la solución también. MUY UTIL.

    Hi,
    We are using Zimbra Mail Server configured over the linux platform and getting the same error message of encryption and pop3 failure so what would be an appropriate solution to get short out of this type of reported root cause.

    Novice computer user looking for help. Sorry if this does not make sense. Outlook 2010 in Windows 7 Professional machine. Received error code 0x800CCC1A after 9/15 windows update. Outlook will not receive any emails. No luck finding a solution online. I noticed in your above post on 9/14/2016 that you also had a similar problem. I know nothing about an Exchange Management Shell. Would I be able to reset the PopProxy to active status and if so how would I go about doing it? Thanks!

    Hi Ken, you will only have access to Exchange Management Shell if you are running an Exchange Server. If this is happening at work then you can try contacting your IT support. If your are experiencing this at home, have you tried the solutions on this Microsoft forum http://answers.microsoft.com/en-us/msoffice/forum/msoffice_outlook-mso_other/in-outlook-2010-i-receive-error-report-0x800ccc1a/74f2a191-69db-4ad2-8a48-a73fd2250d85?auth=1? The topic on that forum specifically addresses the issue in Outlook 2010, which you are running. If none of the solutions work for you then please post your question on that forum so Microsoft can help you. Good luck!
