Summary – This article will walk you through the easy process on how to remove encryption in Outlook emails. The instructions are applicable to Microsoft Outlook 2019, 2016, 2013, 2010, and earlier versions.

Basically, encryption is the technique of converting text data or any other format into an encoded form that is impossible to read using an encryption key. To read the encrypted data, it must be decrypted (decoded) using the appropriate decryption key. Data encryption’s functionality is to ensure data security, particularly for data transferred via a network.

Now, we know that Outlook is one of the most used email clients and many users use this email application to share some confidential data. Hence many of them want the encryption in it as well.

Moreover of we talk about the encryption in Outlook email messages then it is refers to the process of converting plain text into ciphertext. This encrypted communication is only available to the person who possesses a private key, which must be matched with the public key.

Encrypting and decrypting emails in Outlook may appear to be a difficult process, but it is actually fairly simple and straightforward.

We’ll go through how to encrypt Outlook email, how to send encrypted email from Outlook, and how to remove encryption in Outlook emails in this part.

That Digital ID is supplied in the form of an executable installer that will add a certification to your machine automatically. After you install Digital ID, it will be available in Outlook and other Office programmes.

Step 2: Set up Digital ID in Outlook 2010, 2013, 2016, and 2019.

To set up a digital certificate or Digital ID in Outlook 2010, 2013, 2016, follow the instructions below.

After receiving the Digital ID from the certifying body, we must configure the Digital ID in Outlook.

To specify a digital ID in Outlook, follow the procedures shown below.

1. Navigate to the File tab, then to Option, and finally to Trust Center.
