We&#8217;re evaluating potential remediation strategies to resolve user impact as soon as possible.  <\/p>\n<p>  Scope of impact: Your organization is affected by this event, and some users may receive failures when creating channels with Channel Capabilities or shared channels in Microsoft Teams. This section may be updated as the investigation progresses.  <\/p>\n<p>  Start time: Saturday, August 1, 2026, at 1:35 AM UTC <\/p>\n<p>  Root cause: A recent service update migrated JavaScript
