What the models said for it

Verbatim evidence the judge attached to positive labels.

“If an organization uses Windows and O365 exclusively, Copilot is the default choice due to seamless access to SharePoint documents without leaving the app.” Qwen 3.7 Flash · Enterprise AI · comparative prompt · first choice
“my default recommendation would be Microsoft 365 Copilot if your employees already live in Microsoft 365 and Teams” GPT-5.4 mini · Enterprise AI · paraphrase prompt · first choice
“My default recommendation: choose Microsoft 365 Copilot if your company already runs on Microsoft 365” GPT-6 Luna · Enterprise AI · paraphrase prompt · first choice
“If you're on Microsoft 365, Microsoft Copilot is the strongest overall recommendation for mid-market B2B” DeepSeek V4 Flash · Enterprise AI · direct prompt · first choice

And against it

Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

“Multiple controversies—EchoLeak (CVE-2025-32711) enabled zero-click data extraction via email injections; summarized confidential emails ignoring DLP/sensitivity labels.” Grok 4.1 Fast · Enterprise AI · negative prompt · hard negative
“Microsoft 365 Copilot was exploited via a zero‑click prompt injection in email (CVE‑2025‑32711), exfiltrating data from OneDrive/SharePoint/Teams without user action.” GLM 4.7 FlashX · Enterprise AI · negative prompt · hard negative
“Do not deploy M365 Copilot unless you have spent months cleaning up internal file-sharing permissions” Gemini 3.5 Flash · Enterprise AI · negative prompt · hard negative
“Repeatedly flagged in data-risk reports for accessing sensitive company data” DeepSeek V4 Flash · Enterprise AI · negative prompt · hard negative

Search figures are US estimates from DataForSEO, read October 5, 2026; AI search demand is its modeled, directional estimate, not a count of queries to any assistant. The answers are this edition's. Two measurements side by side: neither is read as the cause of the other.

Claim this page

Claiming is free and changes nothing in the data. A claimed page shows a verified contact who is told when each edition publishes and when Microsoft 365 Copilot's standing changes by more than the noise floor; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as Microsoft 365 Copilot, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

What a new claim receivesHide what a new claim receives

A new claim receives the current edition's vendor brief for Microsoft 365 Copilot by email, built from the raw record of the edition. It shows:

  • where Microsoft 365 Copilot is named, by buyer and by framing, and which cells hold its first choices;
  • the claims the models make when they name it, ranked, with the strongest and the weakest quoted;
  • its vocabulary against the segment leader's, and the pages the models cited;
  • who was chosen in the answers that did not name Microsoft 365 Copilot, and every reason the record gives;
  • a battlecard for each top rival: the head-to-head split, why they win, and the reservation quoted against them;
  • one page of published figures cleared to show a buyer.
The subscriber app

A verification link goes to your work email; an address at microsoft.com is approved on the spot, any other is reviewed by hand. Your email is never published. Claiming gives no say over labels, shares, verdicts or which quotes appear.
