Using classic Outlook for Windows in business environments
I've stumbled on something while trying to fix another annoyance (no luck on that yet).
I have three email accounts: Hotmail, Gmail and Comcast.
Open Settings / Accounts and I see the Manage button next to each. Click on each and notice that two say "Set as primary account", because the other will be the primary. See what happens when switching whichever account to be the primary. Each one creates a DIFFERENT layout when working in Outlook. I found that gmail as primary gives me single line view with preview. Hotmail gives single line view without preview. Comcast gives multi-line view. Maybe something connected with my personal settings somewhere else? Not sure.
