TLS Deprecation Report
How does the TLS Deprecation Report collect data?
Magic. All the relevant information is already available in the message trace logs, the report is just summarizing it.
Sadly no. There is no way to get detailed information about which messages correspond to the data from the TLS deprecation widget, and Microsoft has no plans on actually adding such. So the only method is to go over each of the events in the message trace and check the details there.
I still wonder how the date in TLS deprecated report is collected. Referring to your guidance, I understand that the TLS connection of a client can be found by message trace log/powershell. I have check the TLS connection of all my users. They all using TLS1.2 as found in message trace log similar to your screenshot.
However, when I download the TLS Deprecation Report from Secure Score Dashboard, it still shows a number of users still using TLS1.0/1.1. I have no clue how to figure out how this data be collected. Please advise. Thanks.
