Microsoft's mobile Outlook app can be helpful if you want an alternative to your phone's built-in email client, but it doesn't always nail the tasks you handle every day -- say, following an email thread. Thankfully, Microsoft knows it. The company just unveiled updated Android and iOS apps that tackle some of Outlook's navigational issues. It's decidedly better for back-and-forth conversations, for starters. You'll see more of the conversation at once, and tapping on a conversation will jump to the first unread message to help show what you missed. Also, you only need to tap a quick reply box to start a message to everyone in the thread without losing track of the previous conversation.
