Office 365 Message Encryption

  • Last updated on

Email encryption is used to ensure that only the intended recipient is able to access the email and any attachments. To set up email encryption in Microsoft Office 365, see Email encryption in Office 365 and Define mail flow rules to encrypt email messages in Office 365 .

After you have set up email encryption, you must enable journal report decryption to be able to search for or view encrypted mail content in the Barracuda Cloud Archiving Service.

Enable Journal Report Decryption

Journal report decryption allows you to save a plain text copy of the message, along with the original, encrypted message to the Barracuda Cloud Archiving Service. Journal report decryption is configured using the JournalReportDecryptionEnable setting in the Exchange Management Shell.

To enable journal report decryption: 

  1. Open Windows PowerShell and connect to Office 365 Exchange Online.

    For more information, refer to the Microsoft TechNet article Connect to Exchange Online using remote PowerShell.

  2. Enter the following command, and then press Enter:
    Set-IRMConfiguration -JournalReportDecryptionEnabled $true
    • To disable journal report decryption, replace $true with $false
