It was a 50k image that contained a scanned paragraph of text relating to some employment issue in Australia &#8211; clearly a very focused subject and one that should never really have made it on to a global e-mail. However, for some reason this image (a jpeg) was sent to many thousands of recipients globally&#8230;including the e-mail alias abc@def.com!<\/p>\n<p>The original e-mail, including its 50k image attachment was 4MB in size, the first FW: e-mail in the screenshot below. As folks started to Reply All asking to be removed from the list, the size of the e-mail grew, reaching 6MB in the screenshot &#8211; I did see one that had reached 7MB. Each Reply All message included the original recipient list as text which added to the size. As time went by, hundreds of MB&#8217;s of e-mail hit mailboxes&#8230;slowing down the entire global network.<\/p>\n<p>Even as IT staff issued warnings about Reply All, still people did it&#8230;it took the best part of 48 hours before the e-mails ceased and who knows how long to clean up the mailboxes. You can be sure that some of the mailboxes in the 000&#8217;s that were affected would be unattended in someway, so the legacy of the many 4MB e-mails will live on in the OST&#8217;s (perhaps PST&#8217;s too) and backup devices for a long time to come. A very costly e-mail&#8230;<\/p>\n<p>Lesson learned from this: do not click on Reply All unless it is absolutely necessary. If you do find yourself in the position of having to use Reply All, do try and slim down the e-mail body, i.e. remove unnecessary content such as embedded e-mail addresses etc.<\/p>\n<p><img decoding=\"async\" src=\"http:\/\/www.craigmurphy.com\/blog\/wp-content\/uploads\/2008\/07\/Outlook.jpg\" alt=\"reply all\" \/><\/p>\n<p>Technorati Tags: <a href=\"http:\/\/technorati.com\/tag\/Reply+All\" rel=\"tag\">Reply All<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>An e-mail &#8220;did the rounds&#8221; at our client site last week.
