Why Microsoft 365 Copilot for Client Communications and Reports
Microsoft 365 Copilot taps the information your firm already stores in SharePoint, OneDrive, Outlook, and Teams to accelerate drafting and summarization. For lawyers, the value is practical:
- Turn discovery updates, meeting notes, and filings into concise client letters and executive summaries.
- Maintain tone and format consistency across the team using reusable prompts and templates.
- Reduce back-and-forth time by starting from a high-quality draft that’s grounded in your firm’s documents and decisions.
- Enhance accountability by pairing Copilot with review workflows, tracked changes, and sensitivity labels.
Best practice: Treat Copilot as a drafting accelerant, not an author of record. Always verify facts against the underlying record and apply your professional judgment before sending to clients or opposing counsel.
Prerequisites and Secure Setup
Before deploying Copilot for client-facing work, confirm the following with your IT team:
- Licensing: Microsoft 365 Copilot enabled for your tenant and users, with access to Outlook, Word, Teams, SharePoint/OneDrive. If you use Teams meeting recap features, ensure appropriate licensing is enabled.
- Data access and permissions: Matter files stored in SharePoint with least-privilege access. Confirm that users drafting communications have access to the relevant matter sites and channels.
- Compliance: Sensitivity labels, retention policies, and DLP rules configured for client/matter content. Audit and eDiscovery settings aligned to your firm’s policies.
- Templates: Your firm’s Word and Outlook templates (letterhead, email footers, disclaimers) stored centrally for reuse.
Quick Wins: 10-Minute Actions
- Summarize a deposition transcript in Word: Open the file, select “Catch up with Copilot,” and ask for: “Two-paragraph summary, three key admissions, two open issues.”
- Rewrite an email in Outlook: Draft the gist in bullet points, then “Draft with Copilot” and request “Client-friendly tone, 200 words, bullet-point next steps.”
- Turn a Teams meeting into a client update: In the meeting recap, use Copilot to extract action items and risks, then paste into Word with your firm’s letterhead and refine.
Tutorial: Draft a Client Status Update Email and a Board-Ready Report
This hands-on workflow shows how to move from matter materials to a polished client email in Outlook and an executive report in Word—both accelerated by Copilot.
Scenario
You need to brief a corporate client on litigation status: recent filings, implications, upcoming deadlines, and recommended next steps. The matter has a SharePoint site with pleadings, a case timeline in Excel, and a Teams channel with meeting notes.
What You’ll Use
- SharePoint matter site (source documents and timeline)
- Word with Copilot (for the report)
- Outlook with Copilot (for the client email)
- Optional: Teams meeting recap (to pull action items)
Step-by-Step
- Collect your sources. In the SharePoint matter library, identify:
- Most recent pleading or order
- Case timeline (Excel)
- Latest meeting notes in Teams/OneNote
- Open Word and start a firm template. Use your letterhead/report template so headers, footers, styles, and disclaimers are in place.
- Invoke Copilot in Word. Click the Copilot icon and specify the sources to ground your draft. If the files are in the same tenant and you have access, Copilot can reference them as you prompt.
- Draft the executive report. Use a clear, scoped prompt:
“Draft a two-page litigation status report for a corporate general counsel. Use the complaint filed on [date], the court’s order on [date], and the case timeline in SharePoint. Sections: Background (3–4 sentences), Procedural Posture (bulleted), Key Risks (top 3, with probability/impact), Upcoming Deadlines (table), Recommendations (actionable bullets). Use neutral, concise tone suitable for board distribution.”
Example prompt for Copilot in Word grounded in matter materials - Insert a deadline table. If Copilot returns dates in text, ask:
“Convert the upcoming deadlines into a two-column table: Deadline | Description. Sort by date ascending.”
- Refine tone and audience. Ask Copilot to adjust readability:
- “Tighten to 650–800 words.”
- “Remove internal jargon; keep legal accuracy.”
- “Add one-paragraph executive summary up front.”
- Quality review in Word.
- Turn on Track Changes and manually verify facts against the order and complaint.
- Check defined terms, citations to docket numbers, and client names.
- Apply your firm’s sensitivity label to the document (e.g., Confidential – Client Work Product).
- Save to SharePoint. Store the report in the matter library (e.g., “Client Reports/2025-Weekly-Status-Report.docx”).
- Draft the accompanying client email in Outlook. Start a new message to the client team, then select “Draft with Copilot.” Prompt:
“Write a client-friendly email summarizing the attached status report in 180–220 words. Include three bullets for decisions needed from the client. Maintain a confident, neutral tone. Add a short list of key dates for the next 30 days.”
- Insert the report highlights automatically. If the report is saved in the same tenant, request:
- “Incorporate the executive summary from the Word report saved as ‘2025-Weekly-Status-Report.docx’ in the matter library.”
- Polish and add your legal judgment. Use Outlook’s rewrite options (e.g., “Make it more concise” or “Professional tone”), then confirm:
- Privilege and confidentiality footer present
- Deadlines, dates, and recommendations are correct
- Recipients limited to authorized client contacts
- Send and file. Send the email and save a copy to the matter’s “Client Communications” folder in SharePoint or your DMS.
Professional tip: For long-running matters, maintain a single “living” Word report with a date-stamped executive summary on page one. Each week, have Copilot update only the summary and deadlines section while preserving prior history.
Which Copilot to Use for Which Communication
| Communication Type | Primary App | Copilot Action | Prompt Pattern | Review Focus |
|---|---|---|---|---|
| Client status email | Outlook | Draft with Copilot; rewrite to adjust tone/length | “Audience + length + top 3 points + decisions needed + dates” | Accuracy of dates; confidentiality footer; recipient list |
| Executive report | Word | Summarize sources; structure with headings and tables | “Sources + sections + tone + table requirements + word range” | Defined terms, docket references, risk characterization |
| Board memo | Word | Condense to one page; add executive summary | “One-page limit + key risks/mitigations + next steps” | Strategic clarity; privilege labeling |
| Meeting recap to client | Teams + Outlook | Meeting summary and action items; draft email | “Summarize decisions + open issues + owner/deadline” | Attribution of commitments; follow-up dates |
| Regulatory update alert | Word/Outlook | Summarize regulatory text; explain client impact | “Summarize X; impact on [industry]; recommended actions” | Jurisdictional scope; effective dates; disclaimers |
Advanced Tutorial: Automate Weekly Client Update Digests with Power Automate
This automation reduces administrative overhead by assembling the week’s changes and drafting a client-ready summary using Outlook and Word with Copilot. You’ll use Power Automate to gather the content and Copilot to generate the narrative.
Outcome
A scheduled Friday email to the client listing updated filings, key developments, and next steps—complete with links to documents in SharePoint and a concise summary drafted by Copilot.
Build the Flow
- Create a new cloud flow. In Power Automate, choose “Scheduled cloud flow.” Set recurrence to weekly on Friday at 2:00 PM.
- Use Copilot in Power Automate to scaffold the flow. In the “Describe it to design it” box, type:
“Every Friday, search the SharePoint matter site ‘Contoso v. Fabrikam’ for files updated in the last 7 days. Build a summary list with file names, modified dates, links, and authors. Email the team with the list and a short summary paragraph.”
- Confirm connectors and parameters. Ensure the SharePoint site URL and document library are correct. Add a filter on the “MatterID” metadata column if you use one.
- Compose a digest body. Add a “Compose” action to create a bullet list:
- • [FileName] — updated [ModifiedDate] by [Author] — [Link]
- Prepare a summary prompt for Outlook Copilot. Add an “Outlook: Create draft email” action to the flow. In the body, include the composed list and an instruction at the top for the drafter:
“Use Outlook Copilot to condense the following updates into a client-ready summary (150–200 words). Emphasize material changes, deadlines next 30 days, and decisions required. Maintain professional, neutral tone.”
Below this note, insert the dynamic content from your “Compose” list.
- Address and subject. Set the “To” field to your internal review list (not the client) and subject to “Draft: Weekly Client Update Digest – [Matter Short Name]”.
- Test the flow. Run the flow manually. Open the draft email, invoke Outlook Copilot, and prompt:
“Turn the bullet list into a client-facing weekly update. Include a one-sentence executive summary, three bullets of key developments with links preserved, and a final ‘Next Steps’ section with dates.”
- Review and send. Verify links, privileged content, and tone. Send to the client after attorney approval.
SharePoint updates → Power Automate collects files → Outlook creates draft → Attorney refines with Copilot → Send to client
Governance note: Route the draft to an internal approval mailbox or channel first. Only send to clients after attorney review and quality checks.
Prompt Library for Lawyers
Use these reusable prompt patterns to speed up drafting while controlling scope and tone.
Client Status Email (Outlook)
- “Draft a 180–220 word client update about [matter], based on files updated this week in the [Matter Name] SharePoint site. Include: top 3 developments, decisions needed from client, deadlines in next 30 days. Professional and concise tone. Add confidentiality footer.”
Executive Report (Word)
- “Using [Order dated], [Motion filed], and [Timeline.xlsx], create a two-page executive report with sections: Background, Procedural Posture (bulleted), Key Risks (3 bullets with impact and likelihood), Upcoming Deadlines (table), Counsel Recommendations (bulleted). Neutral tone for a corporate GC.”
Meeting Recap to Client (Teams → Outlook)
- “From the [Meeting Name] transcript and notes, summarize decisions made, open issues, assigned owners, and due dates. Create a client-facing email with three bullets for immediate next steps.”
Regulatory Alert (Word/Outlook)
- “Summarize [Regulation/Case] in 120–150 words. Explain implications for [Industry/Client], effective date, and top 3 required actions. Provide a short, plain-English explanation.”
Quality Control, Privilege, and Governance
Copilot exists within your Microsoft 365 security and compliance boundary, but attorneys remain responsible for accuracy and privilege. Harden your process with these controls:
- Sensitivity labels: Apply “Attorney-Client Privileged” or equivalent labels to all drafts and final communications. Configure automatic footers where permissible.
- Review gates: Require attorney review before client distribution. Use SharePoint approval workflows or Power Automate to enforce.
- Versioning: Keep drafts and sent communications under version-controlled libraries with immutable audit trails.
- Source transparency: When feasible, reference docket entries or dates in the communication so facts can be validated quickly.
- Human-in-the-loop: Always verify case numbers, dates, defined terms, and attributions. Never rely on AI for novel legal analysis or final factual assertions without independent verification.
Checklist before sending: Facts verified, recipients confirmed, privilege label applied, deadlines correct, tone appropriate, links accessible to client.
Troubleshooting and Optimization Tips
- Copilot misses a document you need: Ensure the file is stored in SharePoint/OneDrive within your tenant and you have access. Provide exact file names or paste relevant excerpts into the drafting context.
- Draft is too generic: Add specificity to your prompt: audience, length, sections, risk framing, and required tables. Include the names and dates of key filings.
- Overly long responses: Set clear bounds: “No more than 200 words” or “Two pages; include an executive summary.”
- Inconsistent tone across a team: Maintain a shared prompt library and a Word template. Ask Copilot to “match the style of [Template/House Style]”.
- Confidentiality concerns: Confirm that external recipients are not included in drafting threads. Use secure links with appropriate permissions; avoid embedding sensitive content in emails if links suffice.
- Formatting loss when pasting: Draft complex structures (tables, exhibits) in Word with Copilot, then attach the PDF or DOCX rather than pasting into the email body.
Conclusion
Drafting client communications and reports with Microsoft 365 Copilot can save hours per week while improving clarity and consistency. By grounding prompts in matter sources, using firm templates, and building light automation around SharePoint and Outlook, attorneys produce faster, more reliable updates—without compromising judgment or privilege. Start with the status email and report workflow, then scale to weekly digests and meeting recaps to unlock compounding time savings across your matters.
