When an email is encrypted and the recipient cannot open it, the issue typically revolves around the need for encryption keys. Encryption keys are used to encode and decode the email content, ensuring that only authorized recipients with the correct key can access the information. In this scenario, the user would need to receive the appropriate decryption key from the sender to unlock and read the encrypted email. This exchange ensures that sensitive information remains secure during transmission and is only accessible to intended recipients.

If a Group Policy setting is applied that forces the workstations to use a specific SNTP server, but the system clock on the workstations and the authentication server are out of sync, then this can cause authentication issues and users will be unable to log in. In this case, the most likely cause of the issue is a difference in system clocks and the technician should ensure that the clocks on the workstations and the authentication server are in sync.
