Microsoft 365 can connect a firm's email, documents and collaboration tools. That convenience makes its configuration worth reviewing carefully. One account may reach several parts of the firm's working environment, and a setting chosen during an old migration may still shape today's access. A small law firm does not need to change everything at once. Begin with a documented review of sign-ins, privileged access, sharing and the process for removing access when someone leaves.
Confirm how sign-ins are protected
Ask your administrator which policy currently governs multifactor authentication. Microsoft offers security defaults through Entra ID Free and Conditional Access with appropriate Entra licensing. Business Premium includes Entra ID P1, but the firm's actual subscriptions and configuration should be checked. Microsoft MFA guidance Request evidence of coverage and exceptions, rather than accepting a general statement that MFA is enabled. Include administrators and accounts belonging to contractors. Ask how recovery methods are managed if someone loses a phone or changes a number. Treat policy changes as a planned project. Confirm a tested recovery path, communicate the change and validate it with a small approved group before wider rollout. The person responsible should understand how the firm's existing applications authenticate.
Keep administrative access deliberate
List accounts with elevated privileges and record why each needs them. Ask whether routine email and document work can use ordinary accounts, with administrative activity handled through designated accounts. Review who can grant application permissions and how new integrations are approved. This is also a good time to clarify ownership. The firm should know who controls its tenant, domain and licensing, and how authorized leadership can obtain assistance if the usual administrator is unavailable. Document the recovery process securely without putting passwords into an ordinary shared checklist.
Review external sharing as a workflow
Choose a fictional client document and walk through the sharing process. What link type is selected? Who can open it? Can the recipient edit it? How does staff revoke access when the collaboration ends? Microsoft allows administrators to configure sharing options at organizational and site levels, including default link types and certain guest-access restrictions. The available settings should be evaluated against each workspace's purpose. Microsoft collaboration planning Avoid making a blanket change without checking ongoing work. An unexplained restriction can push staff toward improvised sharing methods. Pair settings with clear instructions and an approved route for legitimate exceptions.
Test the departure checklist
Use a fictional employee to review the sequence for removing access, transferring work, handling shared resources and retaining information under firm policy. Confirm responsibility for active sessions and access to connected applications as well as the core account. Have the firm's legal and records owners determine preservation and retention requirements. Disabling access and deleting information are different decisions. Staff should know which steps need approval and which person makes that decision.
Define what will be checked next
Finish with a short findings list: the setting or process reviewed, the evidence, the owner and the next action. Schedule a follow-up after material changes such as hiring, an office move or a new application integration. Mytek Pros offers Microsoft 365 migration and identity services, including MFA and access configuration. Review the cloud-services scope and contact the team about your California firm's environment. Licensing and service scope should be confirmed before implementation. Technical configuration supports the firm's security program; the firm remains responsible for deciding its legal and professional requirements.
