Outlook. For instance, I can have contents of emails automatically appear in a reading pane, rather than just as a list with subject lines. This is the part that feels most like Outlook software for work. You'd need to turn this feature on, though. It's something you might not want if you check messages a lot from public places and don't want messages to automatically appear. But Gmail doesn't even give you that option unless you install a tool that Google says "may change, break or disappear at any time.''
Outlook also lets you create alternate email addresses without signing up for additional accounts _ up to five a year, or up to 15 at any one time. So you can create "UseThisForSpam(at)Outlook.com'' for dealings with merchants, whereas Google requires you to set up a new Gmail account to get that second address, which you can then link with your main account.
Outlook matches Gmail in letting you use Outlook.com to manage email from other services, such as Gmail and AOL, though neither works with Yahoo Mail unless you pay $20 a year for a Plus account.
Outlook also has tools for keeping your mailbox clean. You can automatically move or delete messages older than a certain number of days. You can also choose to keep only the latest message from that sender. Be careful, though, as I had inadvertently deleted more than 300 messages in a few seconds that way. A more useful option would have been to move only messages that had been read, or to move rather than delete all but the latest message.
One nice touch: Most services send deleted messages to a trash folder, and once you empty that, the messages are gone forever. As a Web-based service, Outlook will try to retrieve messages from its servers if they are still there after you've emptied the trash.
_ Outlook creates special filters for viewing certain types of messages.
Click "Shipping updates,'' for instance, for quick access to emails with UPS, FedEx and other tracking numbers for products you are expecting from merchants. That's something Microsoft also had with its older email
