 After you run the Enable-ExchangeCertificate cmdlet, you might need to restart Internet Information Services (IIS). In some scenarios, Exchange might continue to use the previous certificate for encrypting and decrypting the cookie that's used for Outlook on the web (formerly known as Outlook Web App) authentication. We recommend restarting IIS in environments that use Layer 4 load balancing.

You need to understand how these factors might affect your overall configuration.

-Secure Sockets Layer (SSL) is being replaced by Transport Layer Security (TLS) as the protocol that's used to encrypt data sent between computer systems. They're so closely related that the terms "SSL" and "TLS" (without versions) are often used interchangeably. Because of this similarity, references to "SSL" in Exchange topics, the Exchange admin center, and the Exchange Management Shell have often been used to encompass both the SSL and TLS protocols. Typically, "SSL" refers to the actual SSL protocol only when a version is also provided (for example, SSL 3.0).

 - POP: Don't enable a wildcard certificate for the POP3 service. Instead, use the Set-PopSettings cmdlet to configure the FQDN that clients use to connect to the POP3 service.
 - SMTP: When you enable a certificate for SMTP, you're prompted to replace the default Exchange self-signed certificate that's used to encrypt SMTP traffic between internal Exchange. Typically, you don't need to replace the default certificate with a certificate from a commercial CA for the purpose of encrypting internal SMTP traffic. If you want to replace the default certificate without the confirmation prompt, use the Force switch.

+- $true: Outlook Anywhere clients using TLS don't maintain an TLS connection along the entire network path to the Exchange server.
