Comparing Outlook and Outlook Express

Microsoft offers two products that contain the name Outlook. Although the name Outlook appears in both titles, they are not the same program, and they do not offer the same features.

  • Microsoft Office Outlook 2003    Outlook 2003 provides an integrated solution for managing and organizing e-mail messages, schedules, tasks, notes, contacts, and other information. Outlook works directly with other programs in the Microsoft Office System. Outlook delivers innovations that you can use to manage your communications, organize your work, and work better with other people — all from one place. Features found only in Outlook include support for Microsoft Exchange Server e-mail accounts, Out of Office automatic e-mail replies, group calendar scheduling, multiple address books, tasks, notes, junk e-mail filtering, automatic backup, and archiving of items.

Manage and prioritize your communication

Organize information better to help save time and be more productive.

  • Manage all your e-mail in one place     Access, send, and receive e-mail messages from multiple accounts — including work, personal, or Web-based e-mail accounts — within a single view.
  • Print less, read more     Outlook 2003 makes it easier and more comfortable to read e-mail messages online, including long messages. The Reading Pane appears on the right side of the screen, by default, to display twice as much content and reduce scrolling when you read long messages online.
  • Save time and find messages faster     Find e-mail messages more easily by grouping messages by date, size, conversation, subject, importance, or other criteria.
  • Organize your Inbox     You no longer have to keep all e-mail messages in your Inbox to remind you of action items. Instead, use Quick Flags to flag messages by priority or time sensitivity and find them in whichever folder they are located in.
  • Automatically organize messages and receive reminders     Enhanced rules and alerts organize incoming e-mail messages according to your preferences and automatically trigger reminders or alert you when needed — such as when tasks are due or meetings are about to begin.
  • Find messages easily     Save the results of commonly used searches as Search Folders instead of running common searches each time you need to find the messages. Search Folders provide an automated way to keep relevant messages together, without moving them to other folders. Search Folders require a connection to Microsoft Exchange Server 2003, Exchange 2000, or Exchange 5.5.
  • Access your Contacts, Calendar, and Tasks quickly     Use the new Navigation Pane (or use the Go menu), to access your Contacts, Calendar, Tasks, Folders, Shortcuts, and Journal and find the information you need to answer your e-mail messages, schedule appointments, and finish projects.

Get the information you need

Outlook 2003 can help you get the information you need — and block the information you don't need — to stay productive.

  • Prevent junk mail     The new Junk E-mail Filter helps prevent junk e-mail messages from cluttering your Inbox.
  • Block unwanted attachments     To help prevent unwanted attachments and bulky files from taking up too much storage space, Outlook 2003 blocks e-mail messages and files from people who are not on your Safe Senders List. After you examine and approve the message, Outlook 2003 downloads the full message and attachment.
  • Read e-mail messages regardless of the connection     The new Cached Exchange Mode downloads messages and other Outlook 2003 data to your computer so you can remain productive during network downtime. Cached Exchange Mode requires a connection to Exchange Server 2003.
  • Connection awareness     Indicate if you have a fast or slow connection — or have Outlook 2003 detect it for you. Outlook 2003 adapts its performance by displaying either a preview of a message or the full message, depending on your network speed.
  • Find facts quickly     No need to leave your e-mail program to do research — the new Research task pane brings electronic dictionaries, thesauruses, and online research sites into Outlook 2003 so that you can find information and incorporate the information into your messages. Some functionality in the Research task pane requires a connection to the Internet.

Work with other people more easily

Work together better and help protect against the misuse and unwanted distribution of key company information.

  • Communicate instantly with other people     No need to leave Outlook 2003 to find out if an Instant Messaging contact is online. Initiate Instant Messaging conversations quickly in messages, Contacts, Calendar, and other areas in Outlook 2003.
  • Control distribution of sensitive work     Help protect your company assets by preventing recipients from forwarding, copying, or printing important e-mail messages by using Information Rights Management (IRM) functionality. You can even specify an expiration date for the message; after the expiration date the message cannot be viewed or otherwise acted upon. IRM functionality requires Microsoft Windows Server™ 2003 running Microsoft Windows® Rights Management Services (RMS). By using Microsoft Office Professional Edition 2003, you can use Outlook 2003 to create IRM-protected e-mail messages and grant other people permission to access and modify your e-mail messages. You can also apply policy templates to IRM-protected e-mail messages that you create. By using Microsoft Office Standard Edition 2003, Microsoft Office Small Business Edition 2003, and Microsoft Office Student and Teacher Edition 2003, you can read IRM-protected e-mail messages; with permission, you can modify them as well.
  • Work together better     Save e-mail message attachments to shared workspaces where your team members can get the latest versions, check files in or out, or even save task lists, related files, links, and member lists. You can determine whether team members are online and then use Instant Messaging to send them a message. Shared workspaces require Windows Server 2003 running Microsoft Windows® SharePoint® Services.
  • Spend less time coordinating schedules     Access shared team calendars in Outlook 2003 and view multiple calendars side by side to make scheduling meetings fast and more convenient. You can view your own work and personal calendars, calendars in Windows SharePoint Services, or the calendars of other people who have granted you viewing rights. Sharing team calendars requires Windows Server 2003 running Windows SharePoint Services.
  • Go mobile     If you own and use a Tablet PC, you can use ink markup to annotate e-mail messages in your own handwriting by using a pen input device. You can write notes for personal use or e-mail messages to send to other people.

Outlook 2003 main window

  • Microsoft Outlook Express 6    Included as part of Microsoft Internet Explorer and Microsoft Windows®, Outlook Express is a basic e-mail program. Outlook Express offers standard Internet e-mail and newsgroup access and supports Post Office Protocol 3 (POP3) or Internet Message Access Protocol (IMAP) e-mail accounts. Even though Outlook Express is free and allows you to send and receive e-mail messages, it doesn't provide the advanced functionality of Microsoft Office Outlook, part of the Microsoft Office System.

Considerations for using Outlook and Outlook Express on the same computer

Although you can use both Outlook and Outlook Express on the same computer, you need to think carefully about how you want to use each program. At work, you might choose to use Outlook for both your corporate and personal accounts. Or, you might want to use Outlook for your work e-mail and Outlook Express exclusively for your personal e-mail. Consider this — if you read a message in Outlook Express, it stays in Outlook Express until you delete it. This means the message won't be there for you when you decide to use Outlook later in the day because you already downloaded it from your e-mail server (to another application). It's probably best not to access the same e-mail account on the same computer using two different applications — the messages on that account then divide between two different e-mail applications on the same computer.

 Note   If you are using an IMAP e-mail account, your e-mail messages stay on the server so accessing them from both Outlook and Outlook Express should not cause problems. The same is also true for Web-DAV accounts, known as HTTP e-mail accounts.
