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: Following our successful internal testing and validations we’ve deployed our solution. The deployment is approximately 81 percent complete, and user impact is expected to be addressed as it progresses. Our fix deployment timeline estimates it will have completed and that the impact will be remediated by 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: Basic Authentication credentials aren\u2019t being correctly forwarded to the third-party service, resulting in failures when obtaining free\/busy status responses, and resulting in impact. <\/p>\n
