# Microsoft blames AI-written code backlog for delayed Exchange update

*2026-08-17 · Source: [The Register](https://www.theregister.com/software/2026/08/17/microsoft-blames-ai-for-delayed-exchange-update-cant-say-when-it-will-arrive/5288227)*

Microsoft has delayed a promised Exchange update and says it cannot yet give a new timeline. The company attributes the delay to a backlog of bugs introduced by AI-generated code that its engineers now have to work through.

**Why it matters:** This is a rare admission from a major vendor that AI-assisted coding created real technical debt rather than pure productivity gains, a useful counterpoint to industry claims (including Microsoft's own) about AI dramatically speeding up software development.

**Topics:** llms, products
