Outlook Web App lets you use a Web browser to access your mailbox from any computer that has an Internet connection. You can use the browser to read and send e-mail messages, organize contacts, create tasks, and manage your calendar.
You can access your mailbox through any browser that supports HTML 3.2 and ECMA. This includes Internet Explorer, Mozilla Firefox, Apple Safari, Chrome, and other Web browsers on computers that run UNIX, Apple Macintosh, or Microsoft Windows. For more information, see Supported Browsers for Outlook Web App and Exchange Online. Outlook Web App Light is a simpler version of Outlook Web App that supports almost any browser.
In addition to reading and sending e-mail messages, you can customize your messages by, for example, adding attachments, requesting receipts when a message is read or delivered, and adding a category to a message.
You can use folders to organize your messages just as you'd use a file system to organize papers. You can manage the messages you receive by using rules to sort them into different folders.
By default, Outlook Web App uses Conversation view in all e-mail folders whenever the Reading Pane is turned on. Conversation view displays every message in a conversation in a single view. For more information, see Learn About Conversations.
For more information about how to work with messages, see Mail.
Your calendar is like a calendar on the wall, but with a lot of extra features. When you add an appointment to your calendar, you can customize it in many ways, for example, adding attachments, filling in as many details as you want, setting a reminder, or making it a repeating appointment so it's automatically added to your calendar on a regular basis.
In addition to creating appointments, you can set up meetings. A meeting is just like an appointment, except you send an invitation to other people. Each person you invite gets an e-mail message with the details of the meeting. Depending on their e-mail service, they may be able to use the message they receive to add the meeting to their own calendar.
See Calendar for more information about how to manage your calendar.
The Contacts folder of your mailbox is like a Rolodex or address book with an entry for each person or group you want to store information about. You can create a contact to store information about a person or business you want to communicate with.
Groups let you create a single entry that includes multiple contacts. When you send a message to a group, it goes to every contact in the group.
For more information about Contacts and Groups, see Contacts.
If your have a cloud-based mailbox, you can import contacts from other e-mail accounts. For more information, see Import Contacts.
Your mailbox is ready to use as soon as you sign in. You don't have to change any settings or turn anything on or off to start sending and receiving e-mail messages. However, you might still want to change some settings to suit your preferences.
You can do things such as automatically check spelling in your e-mail message before it's sent, add a signature to the messages you send, and select a default font for your messages.
For more information about how to customize Outlook Web App, see Options Reference.
There is a light version that's optimized for users who are blind or who have low vision. For more information, see Outlook Web App Light.
To get help in the window you're working in, click the help icon on the toolbar.
If you know who administers your e-mail, contact them for information about how to use Outlook Web App over your intranet or the Internet.
When you finish using your mailbox, make sure to click Sign out on the toolbar, and then close all browser windows. Signing out helps prevent someone else from using the computer to access your mailbox. Even if you plan to continue using the computer to visit other Web sites, click Sign out and close all browser windows after every session.
