Thanks for that additional detail, amason1010701. After lifting up this matter on multiple occasions, we do now have an updated alert for this issue. It has been determined that the Verizon Messages - Windows Desktop application is not compatible with Windows 10 computers. As a result, the Windows messaging client is being temporarily removed to prevent syncing issues. As an alternative, it is being recommended to use the web client which you can sign into here:  http://spr.ly/6609ENQhx.
