Bitdefender conflict with Exchange WEP

Bitdefender is conflicting with Windows Extended Protection (WEP) used by Microsoft Exchange.

Symptoms: Credential prompt error -- a requester continually prompts for my email password and in never satisfied.

The email server supplier says that Bitdefender terminates my HTTPS traffic and establishes a new SSL/TLS session.

Workaround: Disabling Bitdefender Encrypted web scan solves the problem.

Adding an exception for the mail server address in Bitdefender's Manage exceptions/Online Threat Prevention doesn't seem to solve the problem unless Encrypted web scan is disabled.

Anyone have advice on how to tell Bitdefender not to interfere in this case?

I am using Bitdefener Antivirus Free | Build on Windows 10 Pro 21H2 19044.2251 and Office 2207 (Build 15427.202210 Click-to-Run)
