MORE INFORMATION
After you apply this hotfix, Outlook Web Access users receive an error message when they try to attach or post an item that exceeds the maximum size limit. The large item is transferred to the server because security restrictions prohibit verification of the attachment on the client computer. However, the large item is not committed to the database if the maximum size limit is exceeded.
