Troubleshoot attachments

ShowI received a message with an attachment, but I can't see or open the attachment.

ShowThe recipient of my message didn't receive or can't open my attachment.


  1. In Contacts, double-click the contact you want to open.
  2. Double-click the contact's e-mail address.
  3. In the Internet format list, click one of the following:
    • Let Outlook decide the best sending format (HTML format)
    • Send plain text only
  4. Click OK, and then click Save and Close.
  • You might have sent the message in MIME format to a recipient whose e-mail application doesn't support MIME format. Use the UUENCODE format to send the attachment again.


  1. On the Tools menu, click Options, and then click the Mail Format tab.
  2. Under Message Format, click Internet Format.
  3. Select the Encode attachments in UUENCODE format when sending a plain text message check box.

ShowI made changes to an attachment but I don't see my changes now.

  • You must save the item to save changes to an attachment in the item. If you open an attachment in an item, make changes to the attachment, and then close the item without saving it, your changes to the attachment are not saved with the item. To save a separate copy of the attachment after you make changes, use the Save As command on the File menu in the program you opened the attachment in.
  • To save all attachment changes, keep the item open while you make changes to the attachment. When you finish your changes to the attachment, save and close the attachment, and then save and close the item.
  • You may have opened more than one copy of the attachment and then made some changes in each copy. If so, only the changes you saved in the last copy you opened are saved with the item.
  • If you created the attachment file, you may have made changes to the original file, not the attachment. Locate and check the original file on your hard disk, and reattach the original file if you need to.

ShowMy attachment does not print.

Attachments will print only from the default printer. For example, if you have printer A set as the default, and you open a message with an attachment and choose to print the message on printer B, the message will be sent to printer B, but the attachment will go to printer A.
