Assume that you try to synchronize a certain mobile phone on a Microsoft Exchange Server 2010 mailbox by using ActiveSync. In this situation, you cannot receive email messages on the mobile phone. Additionally, the mobile phone crashes.


This issue occurs because ActiveSync sends an empty ContentID element for an email message. However, certain mobile phones cannot handle an empty ContentID element value.


To resolve this issue, install the following update rollup:
