While they share similar symptoms, they often point to slightly different underlying issues:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>0x800CCC0E:<\/strong> Usually a &#8220;Connection Failed&#8221; error. It occurs when Outlook cannot find or reach the server at all, often due to a blocked port or incorrect server name.<\/li>\n\n\n\n<li><strong>0x800CCC19:<\/strong> Often a &#8220;Timeout&#8221; error. This occurs when a connection is established, but the server does not respond within the expected timeframe, frequently caused by security software interference.<\/li>\n<\/ul>\n\n\n\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_86 ez-toc-wrap-left counter-hierarchy ez-toc-counter ez-toc-custom ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\" style=\"cursor:inherit\">Table of Contents<\/p>\n<span class=\"ez-toc-title-toggle\"><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1' ><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/mybox.com\/help\/ro\/knowledgebase\/troubleshooting-outlook-errors-0x800ccc0e-and-0x800ccc19\/#Common_Causes\" >Common Causes<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/mybox.com\/help\/ro\/knowledgebase\/troubleshooting-outlook-errors-0x800ccc0e-and-0x800ccc19\/#How_to_Resolve\" >How to Resolve<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/mybox.com\/help\/ro\/knowledgebase\/troubleshooting-outlook-errors-0x800ccc0e-and-0x800ccc19\/#Practical_Implications\" >Practical Implications<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/mybox.com\/help\/ro\/knowledgebase\/troubleshooting-outlook-errors-0x800ccc0e-and-0x800ccc19\/#Summary\" >Summary<\/a><\/li><\/ul><\/nav><\/div>\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Common_Causes\"><\/span>Common Causes<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li><strong>Blocked Ports:<\/strong> Your Internet Service Provider (ISP) may be blocking port 25, or your local firewall is preventing traffic on port 587.<\/li>\n\n\n\n<li><strong>Antivirus Interference:<\/strong> Many antivirus programs include &#8220;Email Scanning&#8221; features that act as a proxy between Outlook and the internet.
