View products that this article applies to.

Symptoms

Consider the following scenario in a Microsoft Skype for Business Server 2015 environment:
  • You apply an instant messaging (IM) filter to prevent users from sending instant messages that contain live (clickable) hyperlinks (URI prefixes with https: aren't in the block list) by using the Set-CsImFilterConfiguration cmdlet.
  • You apply a file transfer filter to block a user's ability to transfer certain types (for example, files that have exe file name extension) of files by using the Set-CsFileTransferFilterConfiguration cmdlet.
  • You send a non-blocked prefix with a blocked file name extension (for example, https://contoso.com/site.exe) IM to another user in the Skype for Business desktop client.
In this scenario, the message isn't filtered.
