I currently have GP 2015R2 and web service in my company. If I disable TLS 1.0 on the server(Windows 2012) that has the web service installed, the web service breaks and users can't access it. If I can disable TLS 1.0 in GP 2016 R2 then I'll probably look into upgrading. Thanks.

    I received the following from GP Tech Support today pertaining to both the web client and the traditional workstation client, including GP 2018.  How can Microsoft not be working to fix this for GP?

    Thank you for your time on the phone today! We discussed the issue you are having after disabling TLS 1.0, and I informed you that GP is not a part of the movement to use a more modern security protocol. If you disable TLS 1.0 in a GP environment - any existing version - the GP login will not work. This is written up and is pending with development, but you cannot currently disable TLS 1.0 and still log into GP.

    Unfortunately, no Jason.  Our client is on 2016R2, they disabled TLS 1.0 and it broke web services.  MICROSOFT NEEDS TO HURRY UP!!  Many companies are quickly disabling TLS 1.0 on their networks and switching to 1.2.
