XWEB: Some Messages Sent From Contact List Are Undeliverable

CAUSE

If the Internet e-mail address was originally saved as a Contact using an Outlook 97 client, the OWA client will not be able to use it. If the Internet e-mail address was originally saved as a Contact using an Outlook 98 client, the OWA client can send to it. This is due to the format in which each Outlook client saves the Internet address. Outlook 97 saves the address enclosed in square brackets (example: Test User[testuser@test.com]) and Outlook 98 will saves the address in it's current format (example: "testuser@test.com"). The brackets surrounding the address cause the message to be undeliverable.
