The hotfix that is discussed in this article is not available for the Chinese version of Microsoft Dynamics CRM or for the Japanese version of Microsoft Dynamics CRM.
An e-mail address is unresolved in the From field on the e-mail activity detail form in Microsoft Dynamics CRM 3.0. However, the e-mail activity does appear on the History tab of the contact or of the account. This problem occurs when you receive an e-mail message in Microsoft Dynamics CRM from a contact or from an account that was converted from a lead. When you send an e-mail message from an existing Microsoft Dynamics CRM contact or account, the e-mail address does not resolve to the contact or to the account record. When you view the e-mail message in Microsoft Dynamics CRM, you receive the following error message:
The sender's email address could not be resolved to a record in the system. At least one recipient could not be resolved to a record in the system.
This problem occurs if you receive an e-mail message in Microsoft Dynamics CRM from an entity that has a duplicate e-mail address. For example, this problem occurs if you receive an e-mail message from a contact that has an e-mail address of email@example.com, and an existing user in Microsoft Dynamics CRM also has an e-mail address of firstname.lastname@example.org.
Note This problem typically occurs if you convert a lead to another entity in Microsoft Dynamics CRM. In this case, the same e-mail address exists in both records.
