As a result, messages that should be blocked may continue to be delivered. This applies   to all Microsoft Teams channels. <\/p>\n<p>  Current status: We&#8217;ve identified an issue with DLP policies in Microsoft Teams not being enforced correctly. We\u2019ve investigated the impacted service environment and identified a token error in the service infrastructure logs, and we believe we&#8217;ve correlated   the error with a recent authentication configuration change that may be causing impact. We&#8217;ve developed a potential fix, and we\u2019re validating this fix in a small testing environment to confirm this fix addresses the impact fully.  <\/p>\n<p>  Scope of impact: Any admin may be impacted and may be unable to enforce DLP policies in Microsoft Teams. This section may be updated as our investigation continues.  <\/p>\n<p>  Next update by: Thursday, July 23, 2026, at 2:30 AM UTC<\/td>\n<\/tr>\n<tr>\n<th>Machine Translation<\/th>\n<td>\u30bf\u30a4\u30c8\u30eb:\u7ba1\u7406\u8005\u304cMicrosoft Teams\u3067\u30c7\u30fc\u30bf\u640d\u5931\u9632\u6b62(DLP)\u30dd\u30ea\u30b7\u30fc\u3092\u5f37\u5236\u3067\u304d\u306a\u3044\u5834\u5408\u304c\u3042\u308b <\/p>\n<p>  \u30e6\u30fc\u30b6\u30fc\u3078\u306e\u5f71\u97ff:\u7ba1\u7406\u8005\u304cMicrosoft Teams\u3067DLP\u30dd\u30ea\u30b7\u30fc\u3092\u5f37\u5236\u3067\u304d\u306a\u3044\u5834\u5408\u304c\u3042\u308a\u307e\u3059\u3002 <\/p>\n<p>  \u8a73\u7d30\u60c5\u5831:Microsoft Purview\u3067\u8a2d\u5b9a\u3055\u308c\u305fDLP\u30dd\u30ea\u30b7\u30fc\u306f\u30dd\u30ea\u30b7\u30fc\u30de\u30c3\u30c1\u3092\u6b63\u5e38\u306b\u691c\u51fa\u3057\u307e\u3059\u304c\u3001Microsoft Teams\u5185\u3067\u671f\u5f85\u3055\u308c\u308b\u5f37\u5236\u63aa\u7f6e\u304c\u9069\u7528\u3055\u308c\u3066\u3044\u307e\u305b\u3093\u3002\u305d\u306e\u7d50\u679c\u3001\u30d6\u30ed\u30c3\u30af\u3055\u308c\u308b\u3079\u304d\u30e1\u30c3\u30bb\u30fc\u30b8\u304c\u5f15\u304d\u7d9a\u304d\u914d\u4fe1\u3055\u308c\u308b\u3053\u3068\u304c\u3042\u308a\u307e\u3059\u3002\u3053\u308c\u306f\u3059\u3079\u3066\u306eMicrosoft Teams\u30c1\u30e3\u30cd\u30eb\u306b\u5f53\u3066\u306f\u307e\u308a\u307e\u3059\u3002  <\/p>\n<p>  \u73fe\u72b6:Microsoft Teams\u306eDLP\u30dd\u30ea\u30b7\u30fc\u304c\u6b63\u3057\u304f\u9069\u7528\u3055\u308c\u3066\u3044\u306a\u3044\u554f\u984c\u3092\u7279\u5b9a\u3057\u307e\u3057\u305f\u3002\u5f71\u97ff\u3092\u53d7\u3051\u305f\u30b5\u30fc\u30d3\u30b9\u74b0\u5883\u3092\u8abf\u67fb\u3057\u3001\u30b5\u30fc\u30d3\u30b9\u30a4\u30f3\u30d5\u30e9\u306e\u30ed\u30b0\u306b\u30c8\u30fc\u30af\u30f3\u30a8\u30e9\u30fc\u304c\u898b\u3064\u304b\u308a\u3001\u6700\u8fd1\u306e\u8a8d\u8a3c\u8a2d\u5b9a\u5909\u66f4\u3068\u95a2\u9023\u4ed8\u3051\u3066\u5f71\u97ff\u3092\u4e0e\u3048\u3066\u3044\u308b\u53ef\u80fd\u6027\u304c\u3042\u308b\u3068\u8003\u3048\u3066\u3044\u307e\u3059\u3002\u6f5c\u5728\u7684\u306a\u4fee\u6b63\u6848\u3092\u958b\u767a\u3057\u3066\u304a\u308a\u3001\u3053\u306e\u4fee\u6b63\u304c\u5f71\u97ff\u306b\u5b8c\u5168\u306b\u5bfe\u51e6\u3067\u304d\u308b\u304b\u3092\u78ba\u8a8d\u3059\u308b\u305f\u3081\u306b\u3001\u5c0f\u898f\u6a21\u306a\u30c6\u30b9\u30c8\u74b0\u5883\u3067\u691c\u8a3c\u3057\u3066\u3044\u307e\u3059\u3002  <\/p>\n<p>  \u5f71\u97ff\u7bc4\u56f2:\u3069\u306e\u7ba1\u7406\u8005\u3082\u5f71\u97ff\u3092\u53d7\u3051\u3001Microsoft Teams\u3067DLP\u30dd\u30ea\u30b7\u30fc\u3092\u5f37\u5236\u3067\u304d\u306a\u3044\u5834\u5408\u304c\u3042\u308a\u307e\u3059\u3002\u3053\u306e\u30bb\u30af\u30b7\u30e7\u30f3\u306f\u8abf\u67fb\u304c\u9032\u3080\u306b\u3064\u308c\u3066\u66f4\u65b0\u3055\u308c\u308b\u5834\u5408\u304c\u3042\u308a\u307e\u3059\u3002  <\/p>\n<p>  \u6b21\u56de\u66f4\u65b0:2026\u5e747\u670823\u65e5\u6728\u66dc\u65e5 \u5348\u524d2\u664230\u5206 UTC<\/td>\n<\/tr>\n<\/tbody>\n<\/table><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>TM1436888 | Microsoft Teams | Admins may be unable to enforce Data Loss Prevention (DLP) policies in Microsoft [&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-17434","post","type-post","status-publish","format-standard","hentry","category-uncategorized"],"_links":{"self":[{"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/posts\/17434","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=17434"}],"version-history":[{"count":0,"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/posts\/17434\/revisions"}],"wp:attachment":[{"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/media?parent=17434"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/categories?post=17434"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/tags?post=17434"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
