You can safely disregard this message. Thank you for your feedback.<\/p>\n<p>[Introduction]<\/p>\n<p>This is a reminder based on our previous communication (<a href=\"https:\/\/admin.microsoft.com\/Adminportal\/Home?ref=MessageCenter\/:\/messages\/MC1117814\" target=\"_blank\">MC1117814<\/a>) regarding the Viva Engage email sender domain update. Please ensure your   email configurations are updated, as we plan to roll out the new email domains for your tenant starting Monday, October 6, 2025.<\/p>\n<p>[When this will happen:]<\/p>\n<ul>\n<li>Rollout begins: Monday, October 6, 2025<\/li>\n<li>Expected completion: Tuesday, October 7, 2025<\/li>\n<li>Applies to U.S. and EU tenants currently receiving messages from @yammer.com and @eu.yammer.com.<\/li>\n<\/ul>\n<p>  <\/p>\n<p>[How this will affect your organization:]  <\/p>\n<p>All emails from Viva Engage will now come from a new domain instead of yammer.com or eu.yammer.com The exact sender domain depends on the data residency for your Viva Engage network:<\/p>\n<ul>\n<li>US geo: from @yammer.com to @engage.mail.microsoft  <\/li>\n<li>EU geo: from EU\u200b.yammer.com to @eu.engage.mail.microsoft<\/li>\n<\/ul>\n<p>In addition to the domain change, Viva Engage email addresses will now include a tenant-specific prefix to help differentiate your organization\u2019s environment such as test and production tenants. For example, fabrikam.onmicrosoft.com will result in a \u201cfabrikam\u201d   prefix. Continuing with this example, sender addresses may include:<\/p>\n<ul>\n<li><a href=\"mailto:noreply_fabrikam@engage.mail.microsoft\" >noreply_fabrikam@engage.mail.microsoft<\/a> \u2013 for digest emails, leader identification, community expert identification, delegate notifications and others.  <\/li>\n<li><a href=\"mailto:notifications_fabrikam@engage.mail.microsoft\" >notifications_fabrikam@engage.mail.microsoft<\/a> \u2013 for community posts, storyline updates, and other user activity notifications.  <\/li>\n<li><a href=\"mailto:announcements_fabrikam@engage.mail.microsoft\" >announcements_fabrikam@engage.mail.microsoft<\/a> \u2013 for leadership announcements and other broad communications.  <\/li>\n<\/ul>\n<p>For networks in the EU geo, you should change the sender domain in the examples above to <a href=\"mailto:noreply_fabrikam@eu.engage.mail.microsoft\" >noreply_fabrikam@eu.engage.mail.microsoft<\/a>, etc.<\/p>\n<p>These changes affect all Viva Engage emails, including notifications, announcements, and digests.<\/p>\n<\/p>\n<p>[What you need to do to prepare:]  <\/p>\n<p>Admins should review these configurations before and during rollout:<\/p>\n<ul>\n<li>Email Transport \/ Mail Flow Rules: Update any rules referencing @yammer.com (or EU.yammer.com) to also include @engage.mail.microsoft (and EU.engage.mail.microsoft) so encryption, forwarding, or redirection rules keep working.<\/li>\n<li>Security Filters: Add the new domains to spam filters or allowlists if they were previously trusted.&nbsp;<\/li>\n<li>Outlook Inbox Rules: Notify users to update personal rules that filter by domain (e.g., moving Yammer emails to a folder). Otherwise, Engage emails may land directly in their inbox.<\/li>\n<li>Safe Senders \/ Allow Lists: Add the new domains to org-level and user safe sender lists to prevent misclassification as junk.<\/li>\n<\/ul>\n<p>Please communicate these changes in advance so users know how their rules or filters may be affected. If you don\u2019t use custom rules, no changes are needed; the switch will occur automatically.<\/p>\n<p>  <\/p>\n<p>Learn more: <a href=\"https:\/\/techcommunity.microsoft.com\/blog\/viva_engage_blog\/viva-engage-email-sender-domain-update\/4442161\" target=\"_blank\">  Viva Engage Email Sender Domain Update<\/a><\/p>\n<p>[Compliance considerations:]<\/p>\n<p>No compliance considerations identified, review as appropriate for your organization.<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>MC1162950 | (Updated) Reminder: Update Email Configurations for Viva Engage Email Domain Migration Classificat [&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-13229","post","type-post","status-publish","format-standard","hentry","category-uncategorized"],"_links":{"self":[{"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/posts\/13229","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=13229"}],"version-history":[{"count":0,"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/posts\/13229\/revisions"}],"wp:attachment":[{"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/media?parent=13229"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/categories?post=13229"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/tags?post=13229"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
