Information about changes to the Send As user right in post-Exchange Server 2003 SP2 hotfixes
After Exchange 2003 SP2 was released, a change was made to the security behavior of the Microsoft Exchange Server Information Store service. This change concerns how users assign the Send As user right. This change is included in all post-Exchange Server 2003 SP2 hotfixes that have a version number of 6.5.7650.23 or a later version number.

Before this change was made, if you assigned Full Mailbox Access user rights to a service account, the service was able to send messages as the owner of the mailbox in some circumstances. After this change was made, mailbox security granularity now requires that you explicitly assign the Send As user right.

Many third-party add-in programs and services send messages for Exchange Server users. These programs and services include mobile device synchronization services. These programs and services may not have been granted Send As user rights. Instead, they may rely on Full Mailbox Access user rights. After you apply this hotfix, a program or a service may no longer function correctly because the program or service account can no longer send messages for other users. For more information about how to assign the Send As user right to a service account, click the following article number to view the article in the Microsoft Knowledge Base:

912918 Error message when an application tries to send a message as another user by using Exchange Server 2003: &quot;Access denied&quot;
