Hi @jamescaselton ​, the technical answer to that is that come Jan 1, 2022, we will no longer be supporting legacy Desktop 7.5. That said, we don’t have a switch that we’ll be toggling that will stop it from working on that date.

You will find a lot of the reasoning behind this listed here:

I know some will continue to use legacy Desktop 7.5 until it no longer works for them. When exactly that will be, I wish I had a real answer for you but, as you’ll read in the above, much of that is not determined by us. For example, both Microsoft and Google are making improvements to the security of email mailbox authentication that will no longer work with our legacy software.

Our recommendation is (of course) to move to a solution that is current and being updated but I know that is easier said than done and some may see how long they can continue to use software that is no longer supported.
