Latest Message<\/th>\nTitle: Some users may be unable to view location and subject details for other users’ Exchange Online calendar items<\/p>\n

User impact: Users may be unable to view location and subject details for other users’ Exchange Online calendar items.<\/p>\n

More info: Affected users may only be able to view the free\/busy availability of other users’ Exchange Online calendars despite having been configured to also view location and subject details for calendar items.<\/p>\n

Current status: We\u2019ve completed the aforementioned final validation of our developed code fix and have begun deploying it to the affected environments. We\u2019ll provide a timeline to remediation as it becomes available. When the fix has completed deployment, admins will need to reapply access permissions for the previously impacted users to restore access and fully resolve the impact. <\/p>\n

Scope of impact: Some users attempting to view Exchange Online calendar items for users’ calendars that they’re configured to have access to may be impacted. This information may be updated as our investigation continues.<\/p>\n

Start time: Tuesday, July 14, 2026, at 12:00 AM UTC<\/p>\n

Root cause: A recent Exchange Online service change introduced a permissions issue that’s preventing some users from viewing location and subject details for other users’ calendars, which is resulting in impact.<\/p>\n
