Many firms buy Microsoft 365 Copilot in 2026 because Word is already there. That is reasonable. Copilot writes the next sentence. The proposal rarely fails on the sentence. It fails on the file nobody opened.
What Copilot sees
The open file. The tenant, if someone connected it. Not first: city, canton or federal. Not the title page of five PDFs with almost the same name. Not the 8.00 m that only sits in the drawing.
- ✓Drafting in Word once the passage is cited: yes.
- ✓Which edition applies before anyone opens Word: no.
- ✓SharePoint stays the archive. Copilot writes in Office. Leistera reads the folder and writes nothing back.
Two tools, one path
First the passage: document, edition, page. Then Word. Copilot can help there if the office wants that. Buy Copilot as a stand-in for the valid edition and you buy the polish and keep the 20 to 30 hours of search.
