Message Summary
The legacy TLS reports, including ‘Monthly Trend of TLS 1.0/1.1 Usage’ and ‘TLS 1.0/1.1 Deprecation Report’ in Service Trust Portal were created to help customers identify clients that are using legacy TLS protocols.
TLS 1.0 and 1.1 have been disabled for most of Microsoft 365 capacities, and the legacy TLS reports became less relevant.
We will remove legacy TLS reports from Service Trust Portal before July 31, 2022.
When this will happen:
Before July 31, 2022.
How this will affect your organization:
TLS 1.0 and 1.1 have already been disabled for most Microsoft 365 services. Clients will be less likely to be able to connect to Microsoft 365 using legacy TLS protocols, and it’s less likely for Microsoft 365 to capture legacy TLS connection signals. You’ll need to use your own internal tools to identify legacy TLS users. Once you do, update your users protocol settings to TLS 1.2 or later.
What you need to do to prepare:
You will need to use your own internal tools to identify legacy TLS users. Update users protocol settings to TLS 1.2 or later.
