# Do coding agents recommend Microsoft 365 eSignature? > Microsoft 365 eSignature was chosen in 8% of 106 judged e-signature sessions, ranking third. Measured with Claude Code, Codex and Cursor. Source: https://armature.tech/library/do-coding-agents-recommend-microsoft-365-esignature Published: 2026-09-17 Publisher: Armature, Inc. (https://armature.tech) --- > Microsoft 365 eSignature was chosen in 8% of 106 judged e-signature sessions, ranking third. It was also raised as a candidate in 10 further sessions without being chosen. This page reports what happened when Claude Code, Codex and Cursor had to solve a problem in e-signature inside a realistic codebase. Not what a chat assistant says about Microsoft 365 eSignature. What an agent actually installed. One thing to read first: every one of those wins came from a **single codebase**. That is a result about one repository rather than about e-signature in general, and the splits below cannot separate the two. Treat them as a description of that repository. ## The numbers | | | | --- | --- | | Category | E-signature | | Sessions in the category | 106 | | Sessions where Microsoft 365 eSignature was chosen | 9 | | Install share | 8% | | Rank in category | 3 of 9 | | Codebases it won in | 1 | | Raised as a candidate, not chosen | 10 | | Chosen when considered | 47% | | Site | microsoft.com | ## By agent With 9 wins spread across three agents, the rates below are small numbers and a difference between them is not yet a finding. They are here because the direction is worth knowing, not because the gap is established. | Agent | Sessions | Chose Microsoft 365 eSignature | Share | | --- | --- | --- | --- | | Claude Code | 35 | 4 | 11% | | Codex | 35 | 2 | 6% | | Cursor | 36 | 3 | 8% | ## By who was asking Microsoft 365 eSignature does much better with one kind of buyer than another. It won 16% of sessions asked as junior developer and 0% of those asked as enterprise team. | Who is asking | Sessions | Chose Microsoft 365 eSignature | Share | | --- | --- | --- | --- | | Junior developer | 58 | 9 | 16% | | Senior engineer | 24 | 0 | 0% | | Enterprise team | 24 | 0 | 0% | ## What Microsoft 365 eSignature was up against The full ranking in e-signature, from the same sessions: | # | Product | Runs won | Share | | --- | --- | --- | --- | | 1 | Dropbox Sign | 32 | 30% | | 2 | DocuSign | 31 | 29% | | 3 | Built in-house (no product adopted) | 11 | 10% | | 4 | Microsoft 365 eSignature **(this page)** | 9 | 8% | | 5 | YouTrust | 9 | 8% | | 6 | Signable | 5 | 5% | | 7 | Adobe Acrobat Sign | 3 | 3% | | 8 | Documenso | 3 | 3% | ## What this means Microsoft 365 eSignature was raised in 10 sessions and chosen in 9. That ratio is balanced enough that the ceiling is presence rather than integration: the product converts reasonably when it is on the table, and it is not on the table often enough. ## Where these numbers come from The 106 sessions in e-signature are part of a published set of 7,958, run with real coding agents inside realistic codebases and judged blind. The full method is on one page: [how we measured this](/library/how-we-measured-this). Every e-signature run can be replayed on [the board](/leaderboards/e-signature). If you work on Microsoft 365 eSignature: the judge recorded a reason for every session where it was raised and passed over. Those reasons are in the transcripts. ## Common questions ### Do coding agents recommend Microsoft 365 eSignature? Yes. Microsoft 365 eSignature was chosen in 9 of the 106 judged sessions in e-signature, a 8% install share, ranking third in its category. ### Does Claude Code recommend Microsoft 365 eSignature? In 4 of the 35 sessions in e-signature run with Claude Code, which is 11%. ### Do different coding agents treat Microsoft 365 eSignature differently? Not much. The three agents chose it at similar rates, between 6% and 11% of their runs. ### How was this measured? Real coding agents at pinned versions were run in sandboxes inside 91 realistic codebases and asked to solve real tasks. A simulated project owner approved or questioned each recommendation before any code was written, and a judge from a model family that builds none of the agents read every session blind. ### How often is Microsoft 365 eSignature considered but not chosen? It was raised as a candidate in 10 sessions without being chosen, and chosen in 9. That is a 47% conversion from considered to chosen. ## Read next - [How to get picked for e-signature by coding agents](https://armature.tech/library/e-signature-coding-agents-playbook) (Markdown: https://armature.tech/library/e-signature-coding-agents-playbook.md) - [Do coding agents recommend Dropbox Sign?](https://armature.tech/library/do-coding-agents-recommend-dropbox-sign) (Markdown: https://armature.tech/library/do-coding-agents-recommend-dropbox-sign.md) - [Do coding agents recommend DocuSign?](https://armature.tech/library/do-coding-agents-recommend-docusign) (Markdown: https://armature.tech/library/do-coding-agents-recommend-docusign.md) - [Do Claude Code, Codex and Cursor pick the same tools?](https://armature.tech/library/do-claude-code-and-codex-agree) (Markdown: https://armature.tech/library/do-claude-code-and-codex-agree.md) --- Armature helps software products get discovered and used by coding agents.
