You are a medical researcher.
You need to ensure that Microsoft 365 Copilot responds to you in a professional manner that is appropriate to your field. What is the best approach to achieve the goal?
Custom instructions allow users to define persistent preferences for tone, style, and response behavior across conversations. Microsoft documentation explains that Custom instructions help tailor Copilot responses to professional roles, communication styles, and domain expectations.
For a medical researcher requiring consistently professional, field-appropriate responses, configuring Custom instructions in Settings ensures that Copilot maintains the desired tone and terminology in future interactions.
Attaching examples influences only a single conversation. Saving prompts to the Prompt Gallery aids reuse but does not enforce tone globally. Copilot Memory stores factual preferences but is not intended for style configuration.
Therefore, the best and most comprehensive approach is to configure Custom instructions in Settings.
