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 services, but major rivals have yet to adopt. (Yahoo comes close but sends you to an outside service, Slice, for that.)
Another filter offers quick access to messages with photo attachments or photo links, and yet another gives you messages with documents.
All of these filters missed some of the relevant messages though, while one gave me a bunch of messages from scammers with attachments to open.
_ Outlook links with Microsoft's online storage service, SkyDrive, to handle large files.
No longer do you have to worry about whether your friend or colleague can receive large attachments. Just let Outlook add the file to SkyDrive and create a link to send by email. You get 7 gigabytes of storage for free. Google doesn't integrate its own storage service, Google Drive, with Gmail the same way.
Again, the advances in Outlook.com are mostly neat rather than essential. If you're already using a Microsoft email account, you
