Estimated reading time: 7 minutes

In the evolving legal landscape, remote collaboration is no longer a convenience—it’s a necessity. Hosting secure client consultations and depositions in Microsoft Teams has become an increasingly standard practice for modern legal professionals. When configured properly, Microsoft Teams provides a compliant, secure, and efficient platform tailored to the high standards required by legal workflows.

With privacy regulations tightening, client expectations rising, and legal technology rapidly advancing, law firms must ensure that every virtual interaction upholds attorney-client privilege and court-admissibility. In this blog post, we dive into how Microsoft Teams—when configured correctly—meets the rigorous demands of legal operations. We’ll highlight essential best practices, showcase the platform’s security functions, and offer actionable guidance for attorneys, legal secretaries, and paralegals engaging in remote legal work.

The legal field has seen a dramatic shift toward digital transformation, accelerated by the pandemic and continuing growth of hybrid and remote work environments. According to Microsoft’s official security and compliance overview, Teams supports an entire suite of features purpose-built for sensitive, compliant communication. With support for encrypted communications, retention and legal hold policies, sensitivity labeling, and guest access controls, Microsoft Teams is arguably one of the most secure platforms available for attorney-client interactions and virtual litigation events such as depositions.

Legal professionals need tools that not only enable effective communication but also maintain the integrity of confidential case information. And Microsoft 365—when configured expertly to your firm’s policies—offers these capabilities with built-in governance.

When it comes to legal operations, the top priorities are confidentiality, compliance, and control. Microsoft Teams provides exactly that, provided firms apply the right configurations. Below are the key features every legal team must understand:

1. Encryption: Protecting Sensitive Data in Transit and at Rest

All data transmitted within Teams—be it chat messages, shared files, or video calls—is encrypted end-to-end:

  • In Transit: Communications are protected by TLS (Transport Layer Security), SRTP (Secure Real-Time Transport Protocol), and DTLS for different parts of transmission, such as chat and media.
  • At Rest: Data stored in Microsoft data centers is encrypted using Microsoft-managed encryption keys by default.

For peer-to-peer video consultations or attorney-witness prep calls, Teams can also enable enhanced encryption for added confidentiality. This level of security makes Teams suitable even for regulated case types, including HIPAA-covered matters or international disputes governed by GDPR or EU Model Clauses.

2. Team and Channel Structure: Building a Secure Collaboration Model

Legal firms should adopt a team/channel structure reflecting attorney-client boundaries:

  • Private Teams for Internal Use: Used by attorneys, legal assistants, and paralegals for firm strategies, these are completely inaccessible to external users.
  • Guest-access Teams for Clients/Witnesses: Enable tightly scoped access for external parties using Microsoft’s granular guest permissions. Clients only see the channels, files, and messages pertinent to their own case.

Sensitivity labels can be applied to set rules around sharing, channel visibility, and device usage. They’re especially helpful for managing access based on confidentiality levels—ensuring tight control over deposition materials, medical records, or client financials.

For any legal proceeding, from civil litigation to regulatory investigations, it’s critical to preserve evidence:

  • Legal Hold functionality in Microsoft 365 allows firms to retain Teams content indefinitely, even if an individual user deletes messages or files.
  • Retention Policies can be configured for any team or channel to automatically retain or delete data per compliance protocols. This is key to maintaining chain-of-custody and ensuring admissibility in court.

These tools satisfy a wide range of legal and regulatory obligations, including HIPAA, GDPR, and SOC 2. Teams’ compliance framework ensures firms can maintain document integrity throughout discovery or audit processes.

To optimize Teams for secure client meetings and formal depositions, law firms must go beyond default settings. Follow these proven best practices from experienced legal technology consultants:

1. Use Private Teams & Channels for Confidential Cases

  • Set up separate Teams per matter or client to isolate access.
  • Create channels within each Team for depositions, filings, negotiations, etc.
  • Default permissions should restrict file downloads and discourage unsanctioned recording.

2. Apply Sensitivity Labels Appropriately

Sensitivity labels define access policies and classification levels. Configure them to:

  • Prevent external sharing of confidential case files.
  • Encrypt content through Microsoft Information Protection (MIP).
  • Define device access controls (block mobile downloads, for instance).

This keeps your communications consistent with internal risk management and compliance frameworks.

3. Activate Multi-Factor Authentication (MFA)

All law firm and third-party participants should have MFA enabled. This protects against stolen credentials—an increasingly common threat vector in cyberattacks targeting legal entities.

4. Regularly Audit and Review User Access before Every Deposition

Before every virtual deposition or sensitive client consultation, perform a detailed audit:

  • Who has access to the channel?
  • Are all external parties still relevant to the case?
  • Are any former associates or ex-clients still listed?

Prune access regularly to ensure current, “least privilege” access control—a fundamental cybersecurity principle.

5. Enable Meeting Policies and Lobby Settings

Use Teams admin settings to:

  • Require participants to enter through the lobby—allowing you to vet identities before admitting them.
  • Disable meeting recordings unless necessary, and store them securely when used.
  • Prevent external chat during depositions unless logged and approved.

These protocols mimic and supplement the controlled environment of in-person legal proceedings.

  • Ongoing Microsoft Admin Support & Compliance Monitoring: Ensure your environment evolves with every regulation and technology update.

We understand that confidentiality, accuracy, and productivity must coexist. Microsoft 365 helps achieve that—but only when deployed with intention and oversight.

If you’re planning to use Microsoft Teams for confidential proceedings, here are six steps to implement immediately:

  1. Create a New Private Team for each legal matter to compartmentalize access.
  2. Apply Sensitivity Labels to control guest sharing and define confidentiality levels.
  3. Use Legal Hold on relevant channels to preserve communications during ongoing litigation.
  4. Train Staff on file-sharing protocols and provision of guest accounts.
  5. Audit User Access every time you host a deposition or client consultation.
  6. Enable MFA and Lobby Settings to reduce unauthorized entry.

By building secure Microsoft Teams environments through these best practices, your legal team will be better protected against data spillage, unethical access, and compliance failures.

With the right strategy, Microsoft Teams is a powerful asset for modern law firms. It balances remote productivity, client service, and courtroom compliance through its rich security ecosystem. From encrypted communication to case-specific Teams and forensic-ready legal holds, the platform enables today’s legal professionals to work confidently in a hybrid world.

However, not all firms have the internal expertise or capacity to configure Microsoft 365 to its fullest legal potential—especially those managing complex or high-stakes matters across multiple jurisdictions.

That’s where we come in.
