Consider the following scenario:
You use the GetItem operation in Exchange Web Services (EWS) to retrieve properties of an email message in a Microsoft Exchange Server 2010 environment.
The email message item has an attachment.
In this scenario, the GetItem operation fails.
This issue occurs because EWS incorrectly adds a ContentID field of the attachment two times to the returned XML. Therefore, the XML schema validation fails.
To resolve this issue, install the following update rollup:
2582113 Description of Update Rollup 5 for Exchange Server 2010 Service Pack 1
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
