Instead of constant pop-ups for every email, Outlook can alert you only for messages that matter.

How to set it up:

1. Go to File → Options → Mail → Message Arrival.
2. Check “Display a Desktop Alert” only for emails that meet specific rules.
3. Combine with Rules → Play a sound or flag for follow-up.

💡 Why it helps: Minimizes distractions while ensuring you never miss critical emails.
