Mail in Outlook Web App

When you open Outlook Web App, the first thing you’ll see is your Inbox. This is where messages sent to you arrive, and this is where you’ll probably spend the most time reading and responding to messages.

What you’ll see in Mail


This is where you’ll find your messages.

  1. Create a new message by clicking new New mail.
  2. Folder list. The folder list includes the folders in your mailbox. It may include other folders, such as Favorites and archive folders. You can collapse this pane by clicking the folder icon at the top. You can expand and collapse folders in this view by clicking the triangle icons next to the folder names.
  3. Search window. Type what you want to search for here, such as the name of a person you want to find messages from, or text that you want to search for to find a particular message.
  4. The message list is a list of the messages in the current folder. Each entry in the list view has additional information, such as how many unread messages there are in a conversation, or if there’s an attachment, flag, or category associated with any messages in the conversation. A conversation can have one or more messages. When a conversation is selected, you can delete it, add a flag, or add a category by clicking the icons. At the top of the list view are filters that you can click to quickly find messages that are unread, that include your name in the To or the Cc line, or that have been flagged. In addition to the filters, you’ll see the name of the folder you’re viewing and the view that you’ve selected.
  • The reading pane is where the conversation that you’ve selected is displayed. You can respond to any message in the conversation by using reply Reply, replyall Reply all or forward Forward at the top of a message to respond to it.

Create a new message

To create a new message:

  1. Click new New mail above the folder list. A new message form will appear in the reading pane.
  2. To add recipients, you can type the name of anyone who is in your contacts folder or organization’s address list, or you can type the email address in the To or cc field. The first time you enter a particular person’s name, Outlook Web App searches for that person’s address. In the future, the name will be cached so it will resolve quickly.
  3. Add a subject.
  4. Type the message you want to send. For information about formatting your message, see Formatting messages in Outlook Web App.
  5. To add an attachment, click insert Insert then Attachment at the top of the screen and browse to the file you want to attach. For more information, see Working with attachments.
  6. To embed a picture in the message so that it appears without the recipient having to open it, click insert Insert, then Picture, and browse to the picture you want to add to your message.
  7. When you’re done and your message is ready to go, click send Send.

Working with drafts

If you can’t finish writing a message right away, or want to wait a bit before you send it, you can click away from it and come back to it later to finish it. Outlook Web App automatically saves your message as you create it and adds it to your drafts folder. When you’re ready to send your message:

  1. Find the Drafts folder in the folder list and click on it.
  2. Click on the message you were working on to see it in the reading pane.
  3. Click edit Continue editing or, if you’ve decided you don’t want to send the message after all, click delete Discard.
  4. If you still want to send the message, finish editing it and click send Send.
