Latest Message<\/th>\nTitle: Users may be unable to view free\/busy status for Gmail users within the Exchange Online calendar <\/p>\n

User impact: Users may be unable to view free\/busy status for Gmail users within the Exchange Online calendar. <\/p>\n

More info: Affected users may see an “Unknown” status for the external Gmail contacts. <\/p>\n

Current status: We’ve initiated the deployment of our fix to our internal environment for final validations. Once complete, we’ll proceed with deploying the fix to the broader affected environment. We anticipate this may take until Wednesday, May 27, 2026 to complete, and will provide an update on the deployment timeline with our next scheduled communication update. <\/p>\n

Scope of impact: Impact is specific to any user attempting to view free\/busy status for Gmail contacts in their Exchange Online calendars. <\/p>\n

Start time: Monday, May 11, 2026, at 7:01 AM UTC <\/p>\n

Root cause: A feature was recently disabled to mitigate an unrelated event, resulting in this impact. <\/p>\n

Next update by: Tuesday, May 26, 2026, at 7:30 PM UTC<\/td>\n<\/tr>\n
