Official SfB 2015 Server Disable TLS 1.0 and 1.1 part 3 guidance

updated 20181107


Microsoft update to what they think they are doing, how they are going to do it, and basically, another waffle episode on their part.

As you may be aware, we have covered the upcoming 31 October 2018 TLS 1.0/1.1 support being removed from O365.  You can find that guidance here.  As promised, Microsoft has finally published the last pieces of the series.
You can find part 3 here.
As usual, I strongly recommend that you start looking at this now – some of this might take a bit of planning and coordination on your part to accomplish in a clean fashion.

Now is the time to get your sales types contacting existing customers and offering to help.  This will not be a clean thing; rest assured that there will be “issues” and IMHO there is significant potential for unintended consequences.

YMMV
