(Updated) Outlook: Delimiter setting admin policy

🚨 The Signal: A new Exchange Online admin policy allows setting a tenant-wide default for comma use as recipient separators in Outlook. This provides granular control over email addressing formats, reducing potential misdelivery risks for organizations using specific naming conventions.

The Impact

Exchange Online admins are affected, with a low security risk related to potential misaddressed emails if not configured appropriately.

• Exchange Online Admins: Gain new policy control over recipient separator defaults.
• All Users: Default email recipient separator behavior may change based on admin policy, potentially reducing addressing errors.

The Action

1. Review the new Exchange Online policy settings for 'Use commas as recipient separators' once available.
2. Determine if your organization's naming conventions (e.g., 'Last name, First name') necessitate enabling or disabling this default.
3. Communicate any changes in default email recipient separator behavior to end-users if the policy is modified.
