Symptoms

Consider the following scenario:

• You have a user (use A) whose email address contains a hyphen (-) in a Microsoft Exchange Server 2010 environment.

• You create a contact that contains a hyphen. The email address of the contact resembles the email address of user A.

• You create an email message by using Outlook Web App.

• You type the email address of user A in the To, Cc, or Bcc box.

• You click the Check Names button.

In this scenario, the email address that you typed is resolved incorrectly to the email address of the contact. Therefore, you send the email message to the wrong recipient unintentionally.For example, user A’s email address is [email protected]. The contact’s email address is [email protected]. You type [email protected] in Outlook Web App. Then, you click the Check Names button. In this situation, the email address is resolved incorrectly to [email protected] instead of [email protected].

Cause

This issue occurs because Outlook Web App uses hyphens as word-breakers. Therefore, Ambiguous Name Resolution (ANR) performs ambiguous matching for the email address, and then selects the incorrect email address.

Resolution

To resolve this issue, install the following update rollup:
