TLS 1.2 Preparation
Is there any documentation or guide on preparing for the TLS changes coming March 1st?
Any documentation I'm finding is very vague and not very useful.
Can we get confirmation on minimum versions of software that will be needed, if any. Or how to determine if your hybrid or ADFS is using TLS 1.2, and how to updated them if needed?
Some specific things I assume we need to verify TLS 1.2 support on;
Outlook
Web browsers
Hybrid / Exchange versions
ADFS setups
Windows OS
A document clarifying how to verify and how to setup TLS 1.2 support to ensure compatibility with O365 on these pieces and others would be useful.
I have had a look around as it was just being discussed here as well and there is no such documentation that I can find, that goes into the details you are after. I think this could be improved with more specifics, though I suspect the impact is small, a checklist like you are suggesting would be really helpful. Here was some info on TLS and ADFS by the way - Managing SSL/TLS Protocols and Cipher Suites for AD FS.
