Learned a new trick today regarding Shoretel. We are prepping to deploy Lync Online out to the company, however Lync and the Shoretel Communicator don't play nice depending on the version. Combine that with Shoretel only prompting once for a client side update when you go between backend versions we could almost guarantee there would be major issues if just pushed out Lync. However found a little trick in the Shoreware director. If you go to "System Parameters" "Other", there is a section that allows you to have a Minimum Allowed Client and a Minimum Required client. If you updated those to be the current or version needed it will immediately prompt and require a client side upgrade on the clients.
