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: Our solution is approximately 95 percent saturated throughout the affected environment and should already be alleviating impact for the bulk of affected users. We’re working with a subset of affected users to validate the efficacy of our solution and obtain additional trace logs capturing the impact should this issue continue to be reproducible, in order to determine any further mitigative actions that may be required to resolve this event. <\/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: Friday, May 29, 2026, at 12:30 AM UTC<\/td>\n<\/tr>\n
