A Lync 2010 user can send a URL when it should be blocked by a URL filter
Consider the following scenario:
- In Microsoft Lync Server 2010 Control Panel, you configure a file filter to block URLs that contain the .exe extension.
- You select the option Enable URL filter and the Block URLs with file type extension option.
- You set the Hyperlink prefix setting to Send warning message.
- After you commit the changes, a Lync 2010 user tries to use an instant message to send a URL that contains an .exe extension to another Lync 2010 user. The URL also contains a hyphen or a colon. For example, the user tries to send http://www.thephone-company.com/app.exe or http://example.com:8080/app.exe in an instant message.
This issue occurs because the special characters are handled incorrectly by the URL parser.
To resolve the issue, install the following cumulative update:
