It's not unusual for people to attach files to messages. When you receive a message with an attachment, you can click on the attachment to view, edit, or download it. Some attachment types will open in a window next to your reading pane, allowing you to read and (in some cases) edit them without leaving Outlook Web App.

Viewing an attachment

When you select an attachment, what happens will vary depending on the attachment type. Many attachments will open in a preview window next to the message. If the attachment can't be opened in the preview window, you'll be prompted to download the attachment.

Attachment types that can be previewed include:

  • Word

  • Excel

  • PowerPoint

  • Most image files

  • .pdf files

Select 返回 at the top of the preview window to close it and return to the message view.

Editing attachments

If your account includes OneDrive for Business, you can edit Word and PowerPoint files in the preview pane, or you can open them using the desktop version of the application. Currently, Excel files can only be edited in the desktop version of the application.

If you don't have OneDrive for Business or want to edit an attachment that's an unsupported file type, you'll have to download and open the file to edit it.

When you edit a linked file, your changes are made on a single copy of the file that all recipients have access to. This saves space in everyone's mailbox, and makes collaboration easier.

You can tell if a file has been sent as a link or as an attachment by the icon. The icon for a linked file has a small cloud in one corner.
