Office 365 Encrypted Email: 1-Day Initial Setup

IT Partner LLC

Boost Microsoft 365 security with default encryption. Elevate messaging protection and implement email encryption and rights protection for sensitive data.

Get secure email messaging implemented in your organization. With the new Microsoft 365 Message Encryption (OME) capabilities, which leverage the protection features in Azure Information Protection, your organization can easily share protected email with anyone, on any device. Users can send and receive protected messages with other Microsoft 365 organizations as well as non-Microsoft 365 customers using, Gmail, and other email services.

Our objective is to enable OME -- Microsoft 365 Message Encryption -- in your Microsoft 365 tenant and provide instruments to control sensitive data with flexible policies or ad hoc customer controls that are built into Microsoft 365.

An implementation project will be considered successful when you:

  • start to send encrypted email from any device
  • easily navigate through encrypted messages
  • deliver encrypted email directly to recipients' inboxes
  • decrypt and read encrypted email with confidence, without installing client software
  • enjoy simplified user management that eliminates the need for certificate maintenance

IT Partner responsibilities

  • Set up Office Message Encryption (OME) in Microsoft 365
  • Create mail flow rules that define the conditions for encryption
  • Bring your own key (BYOK) settings, if needed

Client responsibilities

  • Provide a dedicated point of contact responsible for working with IT Partner and coordinate any outside vendor resources and schedules, if needed
  • Configure all networking equipment, such as load balancers, routers, firewalls, and switches
  • If Microsoft Outlook or other desktop email clients are to be used for connectivity to Microsoft 365, tuning email software on client workstations

Outside the scope of this project (additional cost items)

  • Mail migration services to Microsoft 365
  • AD & group policy settings

Upon completion of the engagement, we will provide a Project Closeout Report. This document will indicate final project status, including evidence of meeting acceptance criteria, outstanding issues, if any, and final budget. If you want more extensive documentation, this can be provided for an additional fee.


  • You must have global admin level access to the source Microsoft 365 tenant

  3. Configuring OME and additional tools
  4. Setting up Exchange Online Transport Rules
  5. Verifying email encryption
  6. Posting implementation tasks


You will be able to use Microsoft 365 Message Encryption (OME) capabilities that protect your mails and mail flow rules that define the conditions for encryption. Your email recipients should be able to receive and reply to your secure emails using any device, with any email client.
