CryptographicException error when Edge Transport service crashes in an Exchange Server 2010 environment

Symptoms
The Microsoft Edge Transport service (EdgeTransport.exe) crashes when an Edge server tries to establish an SMTP session with a remote site in a Microsoft Exchange Server 2010 environment. Additionally, you receive the following CLR exception:
System.Security.Cryptography.CryptographicException: ASN1 bad tag value met.
Cause
This issue occurs because the remote malformed Secure Sockets Layer (SSL) certificate causes the Edge Transport service to crash during the Transport Layer Security (TLS) communication between the Edge server and the remote server.
Resolution
To fix this issue, install Update Rollup 12 for Exchange Server 2010 Service Pack 3.
Status
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
