The Microsoft Office Communicator 2007 R2 client is designed to allow users to initiate file transfers between two Office Communicator 2007 R2 clients. However, sometimes when a user wants to transfer a file to another user quickly, the Communicator 2007 R2 file transfer will fail. When this occurs it is time to figure out what is going on behind the scenes to prevent the Office Communicator 2007 R2 client from performing the transfer of files. This article offers a few suggestions to help eliminate this "gotcha" from your to do list.

The first thing the Communicator 2007 R2 client looks for before starting a file transfer is which group policies are enabled for Communicator 2007 R2. Following are names and descriptions of two policies that pertain directly to Communicator 2007 R2 file transfers.

Prevent File Transfer: This Communicator 2007 R2 group policy removes the "send a file" icon from the Communicator 2007 R2 client’s conversation window and from the Communicator 2007 R2 client’s contact menu.

Allow Transferring of Unencrypted Files: This policy controls the ability to send or receive unencrypted files using Microsoft Office Communicator File Transfer. This policy can be used if Communicator must transfer files to instant messaging (IM) clients that do not support encryption. The default for Communicator 2007 is to transfer files with encryption. However, the file transfer feature in Communicator 2005 was not designed to encrypt file transfers. This group policy provides a form of backward compatibility between Communicator 2007 and Communicator 2005 clients by allowing the transfer of unencrypted files between the two Communicator clients.
