Pitfalls to watch at work
Copilot in Outlook
- A thread summary misses attachments and late edits in quoted text: check amounts and dates in the email itself
- The reply draft picks up the tone of the previous email, including a sharp one: reread before sending
- A personal Copilot Pro subscription on a work mailbox takes company email outside its tenant: work mail needs a business license
Grammarly
- The extension reads everything you type in the browser, including form fields: decide in your corporate policy whether it is allowed on work computers
- Rewriting a sentence changes its legal meaning: in English contracts and claims, accept only spelling fixes
- For text in other languages the service offers almost no suggestions; use LanguageTool for that
