Outlook update lets users choose one or two preview lines for emails

Microsoft began rolling out a July 2026 Outlook update on 6 July that adds a setting for email preview lines. Users can now pick two lines, one line, or none. The change applies to list views in both classic and New Outlook. It does not alter search, rules, flags, or any other triage tools. General availability is expected through July 2026 with no impact on shared mailboxes or mobile apps.
Before this update, Outlook showed a fixed number of preview lines that many users found either too cramped or too noisy. The new toggle simply lets each person adjust that single display choice. The deeper issue remains untouched: people still open Outlook to a wall of messages with no reliable way to separate what needs action today from what can wait. Changing preview lines does not create that separation.
Analysis
Ignore the setting entirely and instead block 25 minutes every morning to run a single Outlook triage pass using flags and Sweep rules you already have. Skip the display tweak.
