Buy Exchange Certificate [BETTER]

An Exchange SSL certificate is an ideal solution for the Microsoft Exchange server, office communication server, and QA testing environment. Exchange Servers (2003, 2007, 2010, 2013, 2016 and 2019 editions) and office communication servers are used for daily business communication to stay competitive in this modern age. The transfer of sensitive information between the web clients and the server can cause a risk without proper security. The answer to this risk is an Exchange SSL certificate.

The certificate allows you to secure multiple domains and hostnames with a single certificate. In addition, all exchange services will have 256-bit encryption, and a third person would not sniff the ongoing communication.

The Unified Communications certificate is explicitly built for the Microsoft Exchange and Office Communication Server environments. Therefore, an enterprise can get an Exchange SSL certificate for multiple ways that MS Exchange is accessed. For example, Autodiscover, web services, OWA, ActiveSync, and Outlook email should be conveyed in a secure environment.

SSL certificate allows the most robust SHA 2 algorithm to transmit emails on the exchange server and authenticate the connecting device and exchange server during the exchange of information. For example, when you use an SSL certificate, you can do the following tasks:

Exchange SSL certificate is ideal for Microsoft Exchange server 2003, 2007, 2010, 2013, 2016 and 2019 versions, SharePoint, Lync server, and office communication server. The certificate provides a secure environment and is compatible with 99.9% of email clients and web browsers.

Microsoft announced the exchange 2016 service in 2015, with few changes compared to previous editions like office 365 hybrid, outlook on the web, DLP and archiving SHA-2 compliant, and additional language support. UCC is helpful to give a safe experience with encrypted communication. Refer to the CSR generation, and SSL installation guide stated as under.

Microsoft Exchange 2013 allows offline support in OWA, better indexing and searching experience with exchange managed store, data loss prevention, and exchange administration center. You can install an Exchange SSL certificate for several hostnames for this service. For that, go through the below guidelines.

Microsoft Exchange 2010 was publicly available in 2009, which brought novel features like a client access server, the ability to combine a mailbox server with a client access server, a personal archive, and many other features. UCC SSL certificate is ideal for exchange 2010 for a secured connection.

Microsoft Exchange 2007 server is an advanced version of the exchange server that can split functions of the exchange server to ease management functions and increase performance. You can install an Exchange SSL certificate with CSR generation by following the below guideline.

Microsoft Exchange (MS Exchange) 2003 requires an SSL certificate for secured communication between two ends (server-server or client-server). MS exchange comes with new features like connection filtering and receipt filtering. It is helpful in large enterprises for distributed exchange server environments.

Comodo Multi-Domain SSL is a prominent security certificate for online businesses, especially for large enterprises. Both versions like www and non-www domains will be covered in this certificate, giving more flexibility to run the website on your own decision. Almost all servers, including Exchange servers 2007, 2010, 2013, 2016, and 2019, are compatible with this Comodo UCC certificate.

Comodo Positive Multi-Domain Wildcard SSL certificate is a vital certificate that protects different levels of wildcard domains (*, * and their subdomains. All subdomains will enjoy strong encryption with 2048-bit root encryption to ensure that each byte of information is encoded to avoid data sniffing activities. In addition, almost all server types, including exchange server versions (2007 to 2019), are compatible with Comodo Positive Multi-Domain Wildcard SSL.

The CA/Browser Forum recently revised the rules regarding issuing SSL Certificates for internal domain names. Certificate Authorities may no longer issue certificates for internal names with expiration dates after November 1, 2015. Microsoft Exchange admins can use the free DigiCert Internal Name Tool to reconfigure their Exchange servers to comply with these new guidelines.

"Very fast delivery. Installation was easy with no problems. If you are installing a wildcard SSL certificate on cPanel, you need to specify the actual domain name, don't try to install it on * , you have to install it on each subdomain such as,,..etc. Use the same certificate for each subdomain you install. Good luck!"

Encryption and digital certificates are important considerations in any organization. By default, Exchange Server is configured to use Transport Layer Security (TLS) to encrypt communication between internal Exchange servers, and between Exchange services on the local server. But, Exchange administrators need to consider their encryption requirements for communication with internal and external clients (computers and mobile devices), and external messaging servers.

Exchange Server 2019 includes important changes to improve the security of client and server connections. The default configuration for encryption will enable TLS 1.2 only and disable support for older algorithms (namely, DES, 3DES, RC2, RC4 and MD5). It will also configure elliptic curve key exchange algorithms with priority over non-elliptic curve algorithms. In Exchange Server 2016 and later, all cryptography settings are inherited from the configuration specified in the operating system. For additional information, see Exchange Server TLS Guidance.

This topic describes the different types of certificates that are available, the default configuration for certificates in Exchange, and recommendations for additional certificates that you'll need to use with Exchange.

Digital certificates are electronic files that work like an online password to verify the identity of a user or a computer. They're used to create the encrypted channel that's used for client communications. A certificate is a digital statement that's issued by a certification authority (CA) that vouches for the identity of the certificate holder and enables the parties to communicate in a secure manner by using encryption.

A certificate contains a public key and attaches that public key to the identity of a person, computer, or service that holds the corresponding private key. The public and private keys are used by the client and the server to encrypt data before it's transmitted. For Windows users, computers, and services, trust in the CA is established when the root certificate is defined in the trusted root certificate store, and the certificate contains a valid certification path. A certificate is considered valid if it hasn't been revoked (it isn't in the CA's certificate revocation list or CRL), or hasn't expired.

The certificate isn't automatically trusted by client computers and mobile devices. The certificate needs to be manually added to the trusted root certificate store on all client computers and devices, but not all mobile devices allow changes to the trusted root certificate store.

To prove that a certificate holder is who they claim to be, the certificate must accurately identify the certificate holder to other clients, devices, or servers. The three basic methods to do this are described in the following table.

You can only use wildcard certificates for host names at the level of the wildcard. For example, you can't use the * certificate for Or, you can't use the * certificate for Older clients, devices, applications, or services might not support wildcard certificates. Wildcards aren't available with Extended Validation (EV) certificates. Careful auditing and control is required. If the wildcard certificate is compromised, it affects every host in the specified domain.

When you install Exchange 2016 or Exchange 2019 on a server, two self-signed certificates are created and installed by Exchange. A third self-signed certificate is created and installed by Microsoft Windows for the Web Management service in Internet Information Services (IIS). These three certificates are visible in the Exchange admin center (EAC) and the Exchange Management Shell, and are described in the following table:

If you remove this certificate, the Web Management service will fail to start if no valid certificate is selected. Having the service in this state can prevent you from installing Exchange updates, or uninstalling Exchange from the server. For instructions on how to correct this issue, see Event ID 1007 - IIS Web Management Service Authentication 041b061a72
