The recipient may have received the OME email messages but attempts to open the message were met with continuous loading prompts.<\/p>\n<p>  Final status: We&#8217;ve completed the redeployment of the recent Exchange Online update and confirmed with affected users that impact is remediated. Some users will need to clear their browser&#8217;s cache before they are able to access OME email messages.<\/p>\n<p>  Scope of impact: Impact was specific to users sending OME email messages who were served through the affected infrastructure&nbsp;and their recipients&nbsp;that used third-party email clients.<\/p>\n<p>  Start time: Thursday, April 27, 2023, at 5:00 AM UTC<\/p>\n<p>  End time: Thursday, April 27, 2023, at 1:55 PM UTC<\/p>\n<p>  Root cause: A recent update to Exchange Online wasn&#8217;t properly deployed to the affected environment and was missing some scripts necessary to facilitate access to encrypted email, resulting in impact.<\/p>\n<p>  Next steps: <br \/>  &#8211; We&#8217;re reviewing the infrastructure responsible for deploying updates to Exchange Online to identify where the failure occurred within the deployment process, allowing us to prevent similar impact in the future.<\/p>\n<p>  This is the final update for the event.<\/td>\n<\/tr>\n<\/tbody>\n<\/table><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>EX547161 | Exchange Online | Users\u2019 Office Message Encryption (OME) email messages sent through Exchange Onlin [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-1310","post","type-post","status-publish","format-standard","hentry","category-uncategorized"],"_links":{"self":[{"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/posts\/1310","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/comments?post=1310"}],"version-history":[{"count":0,"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/posts\/1310\/revisions"}],"wp:attachment":[{"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/media?parent=1310"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/categories?post=1310"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/tags?post=1310"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
