Dear Experts,<br />
<br />
Having done a recent upgrade to Exchange 2016 CU6 over this weekend, we noticed a bizarre problem in which the Outlook Web Access (OWA) page displayed &quot;Something Went Wrong&quot; after logging in.<br />
<br />
The issues turned out to be related to how Microsoft Internet Information Service parses the certificates; the thumbprint for the primary cert was lost and had to be regenerated using powershell.<br />
<br />
<br />
Thanks,<br />

Something went wrong - Exchange 2016 Cumulative Update 6

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Exchange

An email client, email reader or more formally mail user agent (MUA) is a computer program in the category of groupware environments used to access and manage a user's email. A web application that provides message management, composition, and reception functions may internally act as an email client; as a whole, it is commonly referred to as webmail. Likewise, email client may be referred to a piece of computer hardware or software whose primary or most visible role is to work as an email client. Email clients can also have other systems, like calendars, notes and contact managers.

Email Clients

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.
