# Microsoft Exchange Server

14 Hacker News commenters recommended Microsoft Exchange Server and 26 criticized it, November 2025 to November 2026. It was recommended in 9 of 13 months.

**Verdict:** Companies on Microsoft software use it for email and calendars because it integrates tightly with Office and Teams. Critics call it fragile and locking in customers.
