In the current article, we will review three subjects that relate to mailing flow scenario that based on TLS communication. Verify mail server TLS configuration In a scenario in which we create all the required TLS configurations, but for some reason, the mail communication failed. We need to be able to understand what is the…
In the current article, we will review the option implementing the option of Force TLS using Exchange Transport rule & Conditional Mail Routing. The option of Conditional Mail Routing implemented by combining two different Exchange Online components: Exchange Online transport Exchange Online mail connector Versus the former implementation of Force TLS by using “simple Exchange…
In the current article and the next article, we will review a very interesting feature that exists in Exchange Online server and Exchange 2013 on-Premises, which enable us to “activate” the option of Force TLS option using an Exchange Online Transport rule The use of Transport rule for implementing the option of Force TLS comes…
In the current article, we will review the required configuration settings for implementing Force TLS in Exchange on-Premises based environment. In our specific scenario, we need to configure the Force TLS option for the “incoming mail flow”. The meaning is – mail that sent from external mail server to the Exchange on-Premises server that represents…
In the current article, we will review the required configuration settings for implementing Force TLS in Exchange on-Premises based environment. In our specific scenario, we need to configure the Force TLS option for the “outgoing mail flow“. The meaning is – mail that is sent by the Exchange on-Premises server to a specific external domain…
In the current article, we will review the required configuration settings for implementing Force TLS in Exchange Online based environment. In our specific scenario, we need to configure the Force TLS option for the “incoming mail flow”. The meaning is – mail that sent from external mail server to the Exchange Online server that represent…
In the current article, we will review the required configuration settings for implementing Force TLS in Exchange Online based environment. In our specific scenario, we need to configure the Force TLS option for the “outgoing mail flow”. The meaning is – mail that is sent by the Exchange Online server to a specific external domain…
In the current article, is consists of two parts: The part in which we provide a high-level review of the differences that exists between the Exchange on-Premises based environment versus the Exchange Online based environment regarding mail connectors and TLS settings. The reason for examining these differences is, that there are much essential deferences’s begging…
In the current article, we will review the subject of Force TLS in Exchange on-Premises based environment. In Exchange on-Premises based environment, we can choose to implement the option of Force TLS using two options. 1. Domain Security This option defines a set of mail connectors and configuration settings that serve for creating a secure…
In the following article, we will review in more details that implementation of opportunistic TLS on Exchange on-Premises based environment and also in the Exchange Online-based environment. As mentioned, in the Exchange-based environment, the Exchange mail connectors are automatically configured to use the option of opportunistic TLS. The configuration of opportunistic TLS is automatically configured…
In the current article, we will review the two “flavor” of TLS in the Exchange-based environment.The two options for implementing TLS are opportunistic TLS and Force TLS. Exchange-based server (Exchange on-Premises and Exchange Online) are configured by default to use the option of opportunistic TLS. The meaning is that given that the “other side” also…
The purpose of the current article series is, to review the implementation and the use of the TLS protocol in an Exchange-based environment.We will examine the utilization of the TLS protocol in two Exchange environments: Exchange Online Exchange on-Premises The article series The article series that is dedicated to the subject of implementing TLS in…
