Outlook Writing Style Prompt

I want you to act as a writing-style analyst and custom-instructions designer.

Your task is to create a paste-ready set of Custom Instructions for Copilot Draft in Outlook so that drafted emails match my real professional writing style as closely as possible.

Use only Microsoft 365 content that I personally authored. Prioritize:
1. Sent Outlook emails
2. Outlook drafts
3. Teams messages, only as secondary input where useful for tone and brevity patterns

Focus primarily on the last 6 to 12 months, using older messages only if needed to confirm stable patterns.

Objective:
Do not summarize the topics I write about.
Do not describe my work.
Your sole objective is to infer the rules of my writing style so Copilot can reproduce it consistently in Outlook email drafts.

Method:
1. Review a broad and representative sample of messages I personally authored across different contexts, audiences, and lengths
2. Separate signal from noise by ignoring signatures, legal disclaimers, quoted reply chains, forwarded text, copied content, boilerplate, meeting auto-text, and low-signal transactional messages
3. Identify repeatable patterns, not one-off exceptions
4. Distinguish clearly between:
- tone
- structure
- word choice
- sentence length and rhythm
- formatting habits
- how I ask questions
- how I assign actions
- how I communicate decisions
- how I adapt to different audiences
- differences between Dutch and English if they exist
5. Identify both strong patterns to preserve and anti-patterns to avoid
6. Prioritize email-relevant style signals over chat-specific habits

Requirements for the Custom Instructions:
The instruction set must:
- be ready to paste into Copilot Draft settings in Outlook
- sound natural, not generic
- be operational and directive
- reflect how I actually write, not how people generally should write
- work well for emails to colleagues, managers, stakeholders, and external partners
- preserve my likely style across contexts such as updates, decision requests, follow-ups, recaps, feedback, stakeholder communication, and executive summaries
- include language-specific rules if my Dutch and English styles differ
- include subject line guidance
- include clarity and efficiency rules
- include a “Do not” section
- make drafts ready to send, without placeholders

Behavior rules:
- Do not ask me to provide email examples
- Do not ask me to paste messages
- Use only the authored content available in my Microsoft 365 environment
- Ask questions only if absolutely necessary and only when a critical style variable cannot be inferred from my authored messages
- If sufficient signal exists, generate the instructions immediately

Quality bar:
- Be specific
- Be evidence-based
- Do not flatter
- Do not overstate patterns
- Call out uncertainty only inside the instruction wording where evidence is weak
- Do not leak or quote sensitive content
- Prioritize fidelity over generic writing advice
- Keep the result compact and practical

OUTPUT CONTRACT (MANDATORY)
Your output MUST contain only the following two sections, in this exact order:
1. CUSTOM INSTRUCTIONS
2. QUALITY BAR

Do NOT include:
- analysis
- observations
- explanations
- evidence summaries
- notes
- confidence statements
- headings other than the two listed above
- preambles or conclusions

If you are about to include anything outside the two sections above, STOP and remove it.
