## Timeline of updates

- **update** 2026-10-02 21:25 UTC: Between 20:55 UTC on September 25 and 18:46 UTC on September 26, customers using the Microsoft Teams connector may have been unable to authenticate or maintain their connection. Our team traced the issue to an expired authentication credential, immediately issued a new one, and rolled it out across all affected environments, restoring connections.  Some connections may still show a Needs Attention status. Additional action from admins and users may be required. Please see the following Known Issue article for more details: https://www.sfdc.co/je59Zp We apologize for how this incident affected you and your business. We will undertake a full investigation of the incident, establishing the technical trigger, the underlying cause, and preventive action to avoid a repeat in the future.
