Exchange Hosted Encryption (EHE) Upgrade Center
Applies to: Exchange Online Protection
Topic Last Modified: 2014-06-10
Office 365 Message Encryption is the new version of Exchange Hosted Encryption (EHE). Like EHE, Office 365 Message Encryption lets email users easily send encrypted email messages to anyone. If you currently use EHE, you will soon be upgraded to the Office 365 Message Encryption service. All upgrades to the new service are scheduled to occur during the first quarter of 2014.
You will receive an email notification approximately four weeks before your scheduled upgrade. When it’s time to start the upgrade, we will deposit new subscriptions to enable Office 365 Message Encryption for your existing Office 365 organization (tenant) and to transfer your EHE settings. You will receive another email notification when the upgrade is complete.
For guidance about what to expect before, during, and after the upgrade, see the topics listed below.
