Quick Answer: Microsoft 365 supports HIPAA compliance but requires seven configuration phases:
Healthcare organizations should consider Microsoft 365 E5, which costs $57 per user per month. This plan offers advanced security and compliance features.
EPC Group provides HIPAA-compliant M365 deployments. Our M365 HIPAA Hardening accelerator is available for $25,000.
Critical Warning: Deploying Microsoft 365 without HIPAA configuration and then handling PHI violates the HIPAA Security Rule. Penalties range from $100-$50,000 per violation, up to $1.5 million per year per violation category. A single misconfigured SharePoint site can expose thousands of patient records. EPC Group ensures HIPAA compliance is configured before any PHI enters the M365 environment.
EPC Group has deployed HIPAA-compliant Microsoft 365 for healthcare organizations of all sizes — from 50-provider clinics to multi-state hospital systems. Our M365 HIPAA Hardening accelerator ($25,000) delivers all 7 configuration phases in 3-4 weeks.
Microsoft 365 supports HIPAA compliance, but it is not HIPAA compliant out of the box. Microsoft provides a signed Business Associate Agreement (BAA) at no additional cost for M365 E3/E5 customers. However, HIPAA compliance requires proper configuration: DLP policies for PHI, sensitivity labels, email encryption, access controls, audit logging, retention policies, and secure data handling procedures. EPC Group configures all of these controls as part of our HIPAA-compliant M365 deployment methodology.
Microsoft 365 E3 ($36/user/month) meets minimum HIPAA requirements with basic DLP, retention, and audit logging. Microsoft 365 E5 ($57/user/month) is recommended for healthcare organizations because it includes: Microsoft Defender for Office 365 Plan 2, Advanced eDiscovery, Insider Risk Management, Communication Compliance, Information Barriers, and enhanced audit logging. EPC Group recommends E5 for organizations handling significant PHI volumes.
Microsoft provides the BAA through the Microsoft Trust Portal. For enterprise customers: navigate to Microsoft 365 admin center → Settings → Org Settings → Security & Privacy → HIPAA → Accept the BAA. The BAA covers M365 core services (Exchange, SharePoint, Teams, OneDrive), Azure services, and Dynamics 365. EPC Group verifies BAA acceptance as the first step in every HIPAA-compliant M365 deployment.
PHI protection in Teams requires: 1) DLP policies that detect and block PHI sharing in chats and channels, 2) Sensitivity labels on Teams and channels containing PHI (restrict external sharing, prevent downloads), 3) Information barriers between clinical and non-clinical departments, 4) Retention policies for clinical communications, 5) eDiscovery holds for legal and compliance, 6) Guest access restrictions for PHI-labeled teams, 7) Audit logging for all PHI access events. EPC Group configures all of these controls during HIPAA M365 deployment.
HIPAA requires encryption for PHI transmitted electronically. Microsoft 365 provides: Office Message Encryption (OME) for encrypting emails to external recipients, Transport Layer Security (TLS) for in-transit encryption between M365 tenants, S/MIME for certificate-based encryption, and sensitivity labels that auto-encrypt emails containing PHI. EPC Group implements DLP transport rules that automatically encrypt outbound emails containing PHI patterns (SSN, MRN, diagnosis codes) — ensuring compliance without relying on user behavior.
HIPAA requires audit trails for all PHI access. Microsoft 365 provides: Unified Audit Log (captures all M365 activity), Mailbox Audit Logging (tracks email access and actions), SharePoint audit logs (document access, sharing, modifications), Advanced Audit in E5 (long-term retention, high-value event logging), and Microsoft Purview Audit (Premium) for forensic investigation. EPC Group configures audit log retention for 1-7 years (depending on state requirements), creates automated alerts for suspicious PHI access patterns, and builds compliance dashboards for HIPAA officers.
| HIPAA Control | M365 E3 | M365 E5 | Recommendation |
|---|---|---|---|
| BAA Coverage | Yes | Yes | Both covered |
| DLP for PHI | Basic (email only) | Advanced (email + Teams + endpoints) | E5 for full coverage |
| Email Encryption | OME included | OME + S/MIME | E3 sufficient |
| Audit Logging | 90-day retention | 1-year retention + advanced audit | E5 for HIPAA 7-year req |
| Insider Risk Management | Not included | Included | E5 required |
| Information Barriers | Not included | Included | E5 for clinical isolation |
| eDiscovery | Standard | Premium (legal holds, review sets) | E5 for investigations |
| Sensitivity Labels | Manual only | Auto-labeling at scale | E5 for enterprise PHI |
EPC Group Recommendation: Healthcare organizations that manage large volumes of PHI must use M365 E5. The E3 plan does not include:
These features are essential for demonstrating HIPAA compliance to auditors. The difference of $21 per user per month between E3 and E5 is small compared to the penalties for HIPAA violations.
Fix: Auto-encrypt via transport rules detecting PHI patterns
Fix: DLP blocking external sharing of labeled content
Fix: Enable Advanced Audit with 1-year retention
Fix: Conditional Access requiring MFA for all users
Fix: DLP for Teams + sensitivity labels on PHI channels
Fix: Accept BAA through M365 admin center

Microsoft 365 supports HIPAA compliance but requires seven configuration phases:
This guide covers each phase. EPC Group delivers HIPAA-compliant M365 deployments in 8–12 weeks.
A HIPAA-compliant Microsoft 365 deployment requires seven sequential configuration phases. Each builds on the previous one. Skipping phases creates compliance gaps.
Execute the Microsoft BAA before any PHI enters the tenant. The BAA is in the Microsoft 365 admin center under Settings → Org settings → Security & privacy → Business Associate Agreement.
Seven controls are required for Teams and SharePoint in a HIPAA deployment:
HIPAA Security Rule §164.312(b) requires activity reviews. Microsoft 365 provides:
E5 is the most complete HIPAA licensing option. E3 with targeted add-ons covers most requirements at lower per-user cost.
| Feature | E3 ($36/user/mo) | E5 ($57/user/mo) | |---|---|---| | BAA support | Yes | Yes | | Purview DLP | Yes | Yes | | Purview Audit standard | 90-day retention | 90-day retention | | Purview Audit Premium | Add-on required | Included | | Defender for Office 365 Plan 2 | Add-on required | Included | | Insider Risk Management | Add-on required | Included | | Customer Lockbox | Add-on required | Included | | Communication Compliance | Add-on required | Included |No, Microsoft 365 is HIPAA-capable. However, compliance requires your organization to take specific actions. These include:
EPC Group completes these seven phases in 8–12 weeks.
Yes, Microsoft offers a standard HIPAA Business Associate Agreement (BAA) at no cost for enterprise M365 customers. You can find it in the Microsoft 365 admin center.
Make sure to execute the agreement before any PHI enters the tenant. Microsoft will not sign it retroactively.
E5 is the most complete option at $57 per user per month. It includes:
E3 is available at $36 per user per month. It meets most HIPAA requirements with specific compliance add-ons.
Yes, Microsoft Teams can be secure when set up correctly. This includes using DLP policies, sensitivity labels, information barriers, and audit logging.
Many health systems use Teams for clinical care coordination. They do this under a valid Microsoft BAA.
EPC Group ensures compliance by configuring and validating HIPAA controls before any PHI enters Teams.
EPC Group completes HIPAA-compliant M365 deployments in 8–12 weeks. This process includes:
Larger organizations with multiple sites or existing legacy compliance controls may take 12–16 weeks.
