Texts in an office application are cut off or the office application does not respond when you copy the texts from a Lync 2010 instant message input window

Consider the following scenario:
  • You type texts in a Microsoft Lync 2010 instant message conversation window. 
  • You copy the texts before you send the message.
  • You paste the texts into an Office application, such as Microsoft Office Word 2010.
In this scenario, the texts in the Office application are cut off, or the Office application does not respond.

Additionally, you receive an event which resembles the following:

Problem Event Name: AppHangB1
Application Name: <office application name>
Application Version: <version number>
Application Timestamp: <timestamp>
Hang Signature: <xxx>
Hang Type: 0
OS Version: <version number>
Locale ID: 1033
Additional Hang Signature 1: <xxx>
Additional Hang Signature 2: <xxx>
Additional Hang Signature 3: <xxx>
Additional Hang Signature 4: <xxx>
Additional Hang Signature 5: <xxx>
Additional Hang Signature 6: <xxx>
Additional Hang Signature 7: <xxx>

This issue occurs because Lync Server 2010 incorrectly calculates the offset for the end of the fragment in the CF_HTML clipboard format. However, the Office application processes the data from the fragment in the CF_HTML clipboard format instead of the whole HTML content. Therefore, the Office application does not respond when it processes the data.
To resolve this issue, install the following cumulative update:
2496325 Description of the cumulative update package for Lync 2010: April 2011

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
