Consider the following scenario:
- You use a Microsoft Lync 2010 Group Chat client to post a text file in a channel.
- You post a second text file which has the same file name as the first text file that you posted. The second text file has less content than the first text file.
- You use the Open option to download and open the first text file.
- After you open the first text file, you use the Open option to download and open the second text file.
