Existing policy configurations remain unchanged and will resume once normal   operation is restored. <\/p>\n<p>  Current status: We\u2019ve identified a data accuracy issue affecting app usage evaluation, which has the potential to incorrectly classify active apps as unused. As a precautionary measure, we\u2019ve temporarily suspended evaluation of unused OAuth app policies to   prevent unintended actions while we work to address the underlying issue. <\/p>\n<p>  Scope of impact: Your organization is affected by this event, and any users with unused OAuth app policies configured in App Governance may be impacted.  <\/p>\n<p>  Next update by: Tuesday, May 19, 2026, at 1:00 PM UTC<\/td>\n<\/tr>\n<tr>\n<th>Machine Translation<\/th>\n<td>\u30bf\u30a4\u30c8\u30eb:\u30e6\u30fc\u30b6\u30fc\u306f\u672a\u4f7f\u7528\u306eOAuth\u30a2\u30d7\u30ea\u30dd\u30ea\u30b7\u30fc\u3092App Governance\u3067\u4f7f\u7528\u3067\u304d\u306a\u3044\u53ef\u80fd\u6027\u304c\u3042\u308a\u307e\u3059<\/p>\n<p>  \u30e6\u30fc\u30b6\u30fc\u3078\u306e\u5f71\u97ff:\u30e6\u30fc\u30b6\u30fc\u306f\u672a\u4f7f\u7528\u306eOAuth\u30a2\u30d7\u30ea\u30dd\u30ea\u30b7\u30fc\u3092App Governance\u3067\u4f7f\u7528\u3067\u304d\u306a\u304f\u306a\u308b\u5834\u5408\u304c\u3042\u308a\u307e\u3059\u3002<\/p>\n<p>  \u8a73\u7d30\u60c5\u5831:\u5f71\u97ff\u3092\u53d7\u3051\u305f\u30e6\u30fc\u30b6\u30fc\u306f\u30dd\u30ea\u30b7\u30fc\u8a55\u4fa1\u304c\u4e00\u6642\u7684\u306b\u505c\u6b62\u3055\u308c\u3066\u3044\u308b\u3053\u3068\u306b\u6c17\u3065\u304f\u304b\u3082\u3057\u308c\u307e\u305b\u3093\u3002\u3053\u308c\u306b\u3088\u308a\u30a2\u30e9\u30fc\u30c8\u306f\u751f\u6210\u3055\u308c\u305a\u3001\u30a2\u30d7\u30ea\u306e\u7121\u52b9\u5316\u306a\u3069\u306e\u30ac\u30d0\u30ca\u30f3\u30b9\u64cd\u4f5c\u3082\u884c\u308f\u308c\u307e\u305b\u3093\u3002\u65e2\u5b58\u306e\u30dd\u30ea\u30b7\u30fc\u69cb\u6210\u306f\u5909\u66f4\u3055\u308c\u305a\u3001\u901a\u5e38\u306e\u904b\u7528\u304c\u5fa9\u65e7\u3059\u308c\u3070\u518d\u958b\u3055\u308c\u307e\u3059\u3002<\/p>\n<p>  \u73fe\u72b6:\u30a2\u30d7\u30ea\u306e\u5229\u7528\u8a55\u4fa1\u306b\u5f71\u97ff\u3092\u4e0e\u3048\u308b\u30c7\u30fc\u30bf\u6b63\u78ba\u6027\u306e\u554f\u984c\u3092\u7279\u5b9a\u3057\u307e\u3057\u305f\u3002\u3053\u308c\u306b\u3088\u308a\u3001\u30a2\u30af\u30c6\u30a3\u30d6\u306a\u30a2\u30d7\u30ea\u304c\u8aa4\u3063\u3066\u672a\u4f7f\u7528\u3068\u5206\u985e\u3055\u308c\u308b\u53ef\u80fd\u6027\u304c\u3042\u308a\u307e\u3059\u3002\u4e88\u9632\u63aa\u7f6e\u3068\u3057\u3066\u3001\u672a\u4f7f\u7528\u306eOAuth\u30a2\u30d7\u30ea\u30dd\u30ea\u30b7\u30fc\u306e\u8a55\u4fa1\u306f\u4e00\u6642\u7684\u306b\u4e00\u6642\u505c\u6b62\u3057\u3001\u6839\u672c\u7684\u306a\u554f\u984c\u306e\u89e3\u6c7a\u306b\u53d6\u308a\u7d44\u3080\u9593\u3001\u610f\u56f3\u3057\u306a\u3044\u884c\u52d5\u3092\u9632\u304e\u307e\u3057\u305f\u3002  <\/p>\n<p>  \u5f71\u97ff\u7bc4\u56f2:\u8cb4\u7d44\u7e54\u306f\u3053\u306e\u30a4\u30d9\u30f3\u30c8\u306e\u5f71\u97ff\u3092\u53d7\u3051\u3066\u304a\u308a\u3001App Governance\u3067\u672a\u4f7f\u7528\u306eOAuth\u30a2\u30d7\u30ea\u30dd\u30ea\u30b7\u30fc\u3092\u8a2d\u5b9a\u3057\u3066\u3044\u308b\u30e6\u30fc\u30b6\u30fc\u306f\u5f71\u97ff\u3092\u53d7\u3051\u308b\u53ef\u80fd\u6027\u304c\u3042\u308a\u307e\u3059\u3002<\/p>\n<p>  \u6b21\u56de\u66f4\u65b0:2026\u5e745\u670819\u65e5\u706b\u66dc\u65e5 \u5348\u5f8c1\u6642 UTC<\/td>\n<\/tr>\n<\/tbody>\n<\/table><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>DZ1314603 | Microsoft Defender XDR | Some users may be unable to use unused OAuth app policies in App Governan [&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-16352","post","type-post","status-publish","format-standard","hentry","category-uncategorized"],"_links":{"self":[{"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/posts\/16352","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=16352"}],"version-history":[{"count":0,"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/posts\/16352\/revisions"}],"wp:attachment":[{"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/media?parent=16352"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/categories?post=16352"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/tags?post=16352"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
