Issue Description: Users may not receive email notifications generated from the SharePoint Online Rules feature.

More info: Users can create a new rule with the same settings as an affected rule to bypass the impact while we work to resolve this issue.

Scope of impact: Any user expecting SharePoint Online rules email notifications may be affected.

Root Cause: A recent feature update contains a code error that’s preventing email notifications from generating as expected, resulting in impact.

Next steps: Microsoft are reviewing our feature update protocols to ensure similar code errors are caught and addressed ahead of deployment to prevent this from reoccurring.
