If you enable the Exchange Error Reporting feature, Microsoft Exchange will automatically send error reports to Microsoft without bothering you. If an error occurs, the server uses HTTPS to send information to Microsoft over an encrypted channel. This information is stored in facilities with controlled access and is used only to improve Microsoft products. Exchange Error Reporting does not intentionally collect any personal information such as e-mail addresses. However individual error reports may inadvertently contain personal information. While such information could potentially be used to determine the identity of Microsoft Exchange Server users, if present, it will not be used.
