How your SafeSend Web add-in behaves during a network interruption isn't random. It is dictated by the manifest you choose. SafeSend provides three pre-configured manifests to control security policies, offline access, and connectivity rules. Understanding the differences is key to ensuring a seamless and secure experience for your users.

SafeSend Manifest Configuration Options

Choosing the right manifest depends on your organization's security posture, user workflow, and compliance needs. 

Enforced Protection Mode

Choose this if your organization is seeking a balance between robust security and practical usability.

This manifest is the best-of-both-worlds solution. It enforces your security policies to prevent accidental data loss but is designed to handle common issues like network interruptions gracefully, ensuring users remain productive. It provides real security without the heavy-handed restrictions of the strictest mode. 

• Ideal for: A general deployment across most of your users
• User Experience: Secure and reliable, with built-in safeguards
• Core Benefit: Enforces security rules while maintaining a smooth workflow

User Experience

Emails are checked as you're composing. If a review is needed, tips are provided insight at the top of the email asking you to Review. (Clicking Dismiss only dismisses the tip, not the need to review.) If the task pane is pinned, it will also appear in there. In the event of a loss of connectivity to the SafeSend web server, end users will still be able to click Send Anyway and bypass SafeSend. End user won't be able to use Outlook Offline Mode. 

User Prompt Mode

Choose this if your primary goal is to educate users and foster security awareness with minimal disruption.

This manifest acts as a helpful "guardrail" rather than a locked gate. It alerts users to potential issues with their email but ultimately trusts them to make the final decision. It's the best choice for organizations that prioritize workflow speed and user autonomy while still encouraging secure practices. When using in Outlook Offline Mode, 

• Ideal for: Organizations with a strong culture of trust
• User Experience: Lowest friction; policies are advisory
• Core Benefit: Promotes awareness without blocking productivity

User Experience

Emails are checked as you're composing. Tips are provided in the task pane asking you to Review or Send. When the end user clicks Send without reviewing, these three choices come up every time: Send Anyway, Review, or Don't send. In the event of a loss of connectivity to the SafeSend web server, end users will still be able to click Send Anyway and bypass SafeSend. In Outlook Offline Mode, end users can hit Send and the email will wait in the Outbox and send automatically upon reconnection to the internet, bypassing SafeSend (acting as if there is no add-in).

Legacy Compatibility Mode

Choose this if your organization operates under strict compliance regulations or requires the absolute highest level of security with no exceptions.

This is your "zero-trust" option. In this mode, sending is completely blocked until all SafeSend validations are passed—no overrides are possible. It is essential for legal, financial, or healthcare industries where compliance is mandatory. It also perfectly mimics the behavior of the legacy SafeSend add-in (v5.5), making it ideal for organizations that want to maintain that specific, strict user experience.

• Ideal for: Legal, finance, and other highly regulated industries
• User Experience: Most restrictive; security is non-negotiable
• Core Benefit: Guarantees compliance and ensures no email ever bypasses SafeSend

User Experience

Emails are checked at the moment you click Send. If there is something within the message to review, the review dialog box will automatically popup. In the event of a loss of connectivity to the SafeSend web server, messages will be saved to the Draft folder and will need to be manually sent once connectivity is restored. End user won't be able to use Outlook Offline Mode.
