SendGuard now works on iOS and Android

SendGuard for Outlook stop emails from being sent to the wrong recipients, protect sensitive data—even after you click send. Many organizations use SendGuard to reduce human error and strengthen email protection across their teams.

SendGuard now works on iOS and Android. This update brings important safeguards to mobile devices. People who respond to emails on their phones often work with less screen space and faster tapping, which increases the chance of sending information to the wrong contact. The new mobile support gives you a checkpoint before your message leaves your device.

Why this matters

How often do you use your phone to send out emails?

• Mobile screens show less detail and users respond faster. These conditions increase the chance of selecting the wrong contact or replying to a large group without noticing.
• Users often select the wrong recipient or reply to large groups without realizing.
• Mobile email use continues to grow across organizations, which increases the need for consistent safeguards.
• Users often send emails while moving between tasks, and quick responses on a phone increase the chance of selecting the wrong recipient.

Now with SendGuard on mobile, it provides a checkpoint before your email leaves your device and reduces the chance of sending information to unintended recipients.

Key features

This release includes the most important protections for mobile users. The notifications are clear and simple so they fit naturally into the Outlook app.

• Recipient notifications show you whether you are emailing internal or external contacts. This gives you a clear review step before you send.

• Reply all alerts notify you when you are about to respond to many people, which helps reduce unintentional wide distribution.

The layout fits into the Outlook mobile experience so the notifications guide you without slowing you down.

Practical Benefits

Mobile users gain an extra review step during fast communication. Protection stays in place whether someone is at their desk or away from the office.

• Users who handle messages during travel or between meetings receive a notification before they send sensitive information.
• Administrators gain coverage across both desktop and mobile, so protection stays consistent.
• Professionals who use their phones for quick responses gain confidence that they are sending messages to the right contacts.

Current limitations

This first release focuses on essential alerts. Advanced features remain part of the desktop version until further development.

• This release focuses on essential alerts.
• Advanced scanning and detailed policy rules remain available on the desktop version only.
• Mobile settings have fewer customisation options because the interface needs to stay simple.
• Larger teams may need planning if they want to enforce specific mobile alerts across all users.

Development Pipeline

More improvements will follow. The goal is to expand functions while keeping the mobile interface simple and efficient.

• More alert types will be added over time.
• Administrative controls will expand so organizations can manage mobile settings with greater accuracy.
• Additional improvements will focus on mobile workflows while keeping the interface straightforward.

We are very enthusiastic about this development and look forward to adding even more features as Microsoft continues to enhance its platform.
