When managing roaming users in Microsoft 365 (Office 365)—users who regularly work outside of the corporate network or move between locations/devices—it’s essential to implement policies that balance security, accessibility, and productivity.
🔐 1. Identity & Access Management
- Azure AD Conditional Access Policies:
- Require MFA for logins outside known/trusted locations.
- Block access from unsupported or risky countries/regions.
- Require compliant or hybrid Azure AD-joined devices.
- MFA (Multi-Factor Authentication):
- Enforced via Azure AD.
- Use Microsoft Authenticator App or FIDO2 keys for mobility ease.
- Named Locations & Sign-In Risk Policies:
- Define trusted IP ranges (e.g., office IPs).
- Enable Risk-Based Conditional Access for anomalous login detection.
💼 2. Device Management (MDM/MAM)
- Use Intune for full MDM on company-owned devices.
- Use App Protection Policies (MAM) for BYOD/mobile scenarios.
- Prevent copy/paste from O365 apps.
- Require PIN for Outlook/Teams.
- Selective wipe on non-compliant devices.
- Compliance Policies:
- Ensure encryption, AV, OS patch levels.
- Auto-remediation or quarantine access for non-compliant endpoints.
🧳 3. Data Loss Prevention (DLP)
- Apply DLP policies in:
- Exchange Online, OneDrive, SharePoint, Teams.
- Define rules for:
- PII, financial data, health data, etc.
- Block or notify on data exfiltration attempts.
- Enable endpoint DLP for off-network file activity tracking.
📨 4. Email & Collaboration Security
- Safe Links & Safe Attachments (Microsoft Defender for Office 365).
- Anti-phishing, anti-malware, and spoof intelligence features.
- External email tagging to alert users.
☁️ 5. Cloud App Security (Defender for Cloud Apps)
- Monitor cloud activity from roaming users.
- Block unsanctioned apps or shadow IT.
- Create session policies for real-time control (e.g., block downloads from OneDrive on unmanaged devices).
📁 6. Data Governance & Access
- Use Sensitivity Labels for classifying documents/emails.
- Implement Auto-labeling for key content types.
- Enable Information Rights Management (IRM) for content protection.
