Why it matters: Rolling out now

The new Outlook for web and Windows now offers expanded Conditional Formatting options, allowing you to highlight emails based on size, read/unread status, presence of attachments, flag settings, categories, or importance. These enhanced rules make it easier to identify critical messages at a glance and visually organize your folders. #newoutlookforwindows
