Latest Message<\/th>\nTitle: Some users may receive failures when creating channels or adding members to shared channels in Microsoft Teams <\/p>\n

User impact: Users may have received failures when creating channels or adding members to shared channels in Microsoft Teams. <\/p>\n

Final status: After a period of monitoring, we confirmed that rolling back the offending update remediated impact. <\/p>\n

Scope of impact: Your organization was affected by this event, and some users may have received failures when creating channels or adding members to shared channels in Microsoft Teams. <\/p>\n

Start time: Saturday, August 1, 2026, at 1:35 AM UTC <\/p>\n

End time: Monday, August 3, 2026, at 7:07 PM UTC <\/p>\n

Root cause: A recent service update migrated JavaScript Object Notation (JSON) deserialization behavior, resulting in scenarios that rely on deserialization to utilize incorrect values and causing users to receive failures, such as when creating channels or adding users to shared channels in Microsoft Teams. <\/p>\n

Next steps:
– To help prevent similar impact in the future, we’re further reviewing our update release procedures to ensure we’re able to better identify issues before changes are deployed. <\/p>\n

This is the final update for the event.<\/td>\n<\/tr>\n
