UI/UX: Clean, familiar, unified inbox view.
Integrations: Deep with Teams, SharePoint, Power Automate.
Performance: Classic is fast; New Outlook lags on notifications.
Pricing/ROI: Prices rising July 2026, but AI/security now bundled in.
Support: Good docs, quality varies by tier.
AI: Copilot summarization + calendar-aware chat — strongest feature. Review collected by and hosted on G2.com.
Notifications are painfully slow — New Outlook can take over 10 seconds just to open an email from a notification. Mail Merge is weak, and a lot of "new" features barely work if you're not on a Microsoft-hosted mailbox. Honestly, Classic Outlook still feels more reliable overall.
