Latest Message<\/th>\nTitle: Some users may see unwanted add-ins appearing automatically across all Outlook clients <\/p>\n

User impact: Users may see unwanted add-ins appearing automatically across all Outlook clients. <\/p>\n

More info: These add-ins are configured to be available to users by admins but aren\u2019t expected to be automatically installed. <\/p>\n

Current status: We’re coordinating with a subset of affected users who are performing the actions needed to remediate the impact to ensure that running the command and installing previously installed apps fully resolves the issue. <\/p>\n

Scope of impact: Impact may occur for some users that may see unwanted add-ins appearing automatically across all Outlook clients. This section may be updated as the investigation progresses. <\/p>\n

Start time: Friday, July 17, 2026, at 10:26 AM UTC <\/p>\n

Root cause: A portion of the Exchange Online add-in sync pipeline isn’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
