Business value
To comply with standard security protocol, all customers' local on-premises servers must meet the TLS 1.2 and current cipher suites requirements. This includes any on-premises server used to communicate server-to-server with online Dynamics 365 or Power Apps services, such as Exchange Server (on-premises) and web servers that are hosting clients or services. Non-supported cipher suites, such as TLS_RSA, will be deprecated.
Feature details
Customers can use their own servers for the following services:
- Server-side sync (for Exchange emails).
- Outbound plug-ins.
- Web (server-to-server) integration.
- Environment discovery using the regional discovery service.
Customers' Dynamics 365 Server computers must meet the standard TLS 1.2 and current cipher suites requirements to continue using these services. Effective March 1, 2021, these services will be interrupted if the customers' servers do not meet these requirements. For more information, go to Solving the TLS 1.0 Problem, 2nd Edition.
