To bypass this issue, admins can run the \u201cSet-App -Identity -OrganizationApp -PrivateCatalog -DefaultStateForUser Disabled\u201d command to remove add-ins that are unintentionally appearing. <\/p>\n<p> Current status: Our deployment is ongoing, and more users may see remediation as it continues. Based on the current rate of progress, we anticipate that this may fully complete deployment by Friday, October 2, 2026. We&#8217;ll provide further updates on this timeline  for remediation with our next scheduled communication update. <\/p>\n<p> Scope of impact: Impact may occur for some users that are viewing their add-ins across all Outlook clients. This section may be updated as the investigation progresses. <\/p>\n<p> Start time: Friday, July 17, 2026, at 10:26 AM UTC <\/p>\n<p> Estimated time to resolve: We anticipate impact to be resolved by Friday, October 2, 2026. <\/p>\n<p> Root cause: A portion of the Exchange Online add-in sync pipeline isn&#8217;t processing add-in state information as expected. This is causing incorrect EnabledStatus values being returned and Outlook automatically displaying add-ins configured as Available, which  is resulting in impact. <\/p>\n<p> Next update by: Wednesday, September 30, 2026, at 7:00 PM UTC <\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>EX1441488 | Exchange Online | Some users may see unwanted add-ins appearing automatically across all Outlook c [&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-18749","post","type-post","status-publish","format-standard","hentry","category-uncategorized"],"_links":{"self":[{"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/posts\/18749","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=18749"}],"version-history":[{"count":0,"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/posts\/18749\/revisions"}],"wp:attachment":[{"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/media?parent=18749"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/categories?post=18749"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/tags?post=18749"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
