257824 OL2000: Differences Between Outlook and Outlook Express


When you receive e-mail messages in Outlook Express, the message may contain different characters in place of extended ASCII characters as noted in the following example:

  • An exclamation point (!) may appear as +ACE-
  • A quotation mark (") may appear as +ACI-
  • An ampersand character (&) may appear as +ACY-
  • The @ character may appear as +AEA-
  • The # character may appear as +ACM-
Also, the e-mail messages may appear to contain these characters along with Hyper-Text Markup Language (HTML) coding for HTML e-mail messages.


This behavior can occur if Outlook Express is configured to read e-mail messages in the default encoding format regardless of the actual encoding format specified in the header of the e-mail message.


To resolve this behavior, disable the "Use default encoding for all incoming messages" feature:

  1. In Outlook Express, click Options on the Tools menu.
  2. Click the Read tab, and then click International Settings.
  3. Click to clear the Use default encoding for all incoming messages check box, click OK, and then click OK.

More Information

This problem typically happens when you receive a message in the UTF-7 encoding format and Outlook Express is set to use the default Western ISO encoding format for all incoming messages. The symptoms of this problem may be slightly different depending on the incoming message format type.
