Mail > Working with Attachments

An attachment can be a file that's created in any program, for example, a Word document, an Office Excel spreadsheet, a .wav file, or a bitmap. You can attach any kind of file that can be accessed from your computer or through your network to any item created in Outlook Web App. You can also remove attachments from an item.

When a message contains an attachment, a paper clip icon attachment icon is displayed next to it in the message list. Calendar items display a paper clip icon in one corner on the calendar view and show a list of attachments when the item is opened. Contacts show a list of attachments when the contact is opened.

When an item with an attachment is opened, the name of the attached file appears in the attachment list. Some attachments, such as .txt and .gif files, can be opened by the Web browser.

How do I attach a file to an e-mail message or other item?

  1. When you create your message, appointment, or contact, click Attachments attachment icon on the item. Messages will have the Attachments attachment icon link in the header of message. Calendar items will have the Attachments attachment icon link in the toolbar or, if the entry is a meeting, just above the message body. Contacts will have the Attachments attachment icon link at the bottom of the Contact page.

  2. In the Navigation Pane, type the path of the file, or click Browse to locate the file.

  3. After you find the file you want to attach, click Open to add it to the attachments list.

  4. Click Attach, and the file will appear under Attachments. Repeat steps 1-3 for each additional file you want to attach.

  5. To return to the form that you were working in, click Done save on the toolbar. The files you selected now appear in the heading next to Attachments.

Long file names may be truncated before the files are attached. This doesn't affect the contents of file. If you're using Internet Explorer 6 with SP2 or a later version, the attached file name is limited to 76 characters. If the file name is truncated to meet this limit, the first two characters of the file name may be changed. Earlier versions of Internet Explorer replace the long file name that has a generic name, such as file name[1].txt.

How do I remove one or more attachments from an item?

  1. Open the message, and then click Attachments in the header.

  2. Under Attachments, select the check boxes next to the files you want to remove.

  3. Click Remove Delete.

  4. Click Done save to save your changes and return to the item.

Attachments aren't copied when you reply to a message. Instead, a placeholder icon appears instead of the file. To include attachments, forward the message instead of replying to it. Before you edit attached files, you need to download them to your computer.

How do I read an attachment?

  • Click the attachment file name. You'll be given the option to either open the attachment using the appropriate application or to save the attachment to disk.

  • For some attachment types, you can use Open as Web Page to open the attachment to a Web page that can be viewed using your Web browser. The file types that can be opened as a Web page include:

    • Word

    • Excel

    • Office PowerPoint

    • Adobe Acrobat .pdf files

Don't open an attachment unless you trust the content and the person who sent it to you. Attachments are a common method for spreading computer viruses. So it's best to use the Open as Web Page option unless you're sure an attachment is safe.

To send an edited attachment, the application used to create the attachment has to be installed on your computer. For example, if you want to edit an attachment that's a Word file, you need to have Word installed on your computer.

  1. Open the message that has the original attachment.

  2. Click the attachment, and then click saveSave to save the attachment to your computer.
