Introduction<\/h2>\n\n\n\n

Modern communication is unimaginable without email correspondence, which is actively used in people\u2019s everyday lives. Outlook Web Access (OWA) is a popular method or interface used by people to securely access their Microsoft Exchange e-mail accounts through any web browser. <\/p>\n\n\n\n

Nevertheless, sending restricted content through the internet connection without proper encryption leaves your email correspondence open to different kinds of threats that may include eavesdropping, man-in-the-middle attacks<\/a>, and data loss. <\/p>\n\n\n\n

To avoid such risks it is very essential to introduce SSL\/TLS encryption on your OWA server in order to preserve the confidentiality and integrity of your emailed correspondences. This article explains the entire procedure of how an SSL certificate can be installed on the OWA server so that the users can get the best possible encrypted connection.<\/p>\n\n\n\n

Understanding SSL\/TLS Encryption for Outlook Web Access:<\/h2>\n\n\n\n

OWA on SSL\/TLS is a method of encrypting communication channels and has become important to ensure that the users\u2019 connection from their browsers to the Exchange server is secure.<\/p>\n\n\n\n

SSL and TLS are Information Security protocols used to create secure connections over the internet. By deploying SSL\/TLS on an OWA server, data launched from the customer\u2019s web browser to the server is encoded effectively shielding terrible identification data for login, emails, and attachment data from piracy.<\/p>\n\n\n\n

In its absence, the following risks are eminent such as; Eavesdropping attacks, man-in-the-middle attacks, and data breach attacks. Furthermore, there are many industry compliances or organizational policies that stipulate that the use of secure means of data transfer is mandatory, which makes SSL\/TLS encryption<\/a> crucial to OWA.<\/p>\n\n\n\n

How to Set up SSL with OWA (Outlook Web Access)?<\/h2>\n\n\n\n

Step 1: Obtain an SSL Certificate<\/h3>\n\n\n\n

They recommended approaching the OWA server security by starting to purchase an SSL<\/a> from a recognized CA. When buying, the fully qualified domain name that is used in connection with the OWA server needs to be indicated.<\/p>\n\n\n\n
