It was reported that Microsoft Direct Access was not working with Legal Evolve
The issue was related to the PC not seeming to have an IP address to bind to when connected to the network over Microsoft Direct Access (VPN)
This was resolved by Editing the OfficeEvolveDesktop.exe.config to reflect the localhost IP address.
This was also tested when connected to the local Network (Not over Microsoft Direct Access) and worked.
This file can be found by right clicking the Evolve Desktop Icon, "Open File Location" and then double click the Bin Folder. Use Notepad to Edit the config but be sure not to add any additional characters or white space. If the file wont save, save it to Desktop and move it back into the bin folder, overwriting the original.
