On Oct 14, 2025, Exchange 2019 and 2016 reach end-of-life and Exchange SE becomes the only supported on-premises Exchange server. In other news, we discuss Microsoft guidance for moving to cloud first identity, HVE and ECS and the extension of basic authentication support to September 2028, the introduction of auto-archiving for Exchange Online, and why Microsoft is deprecating the Contact object from Exchange Online.
This article covers how to use HVE with Azure Automation to send email. HVE is Exchange Online’s High Volume Email solution for internal communications. In the discussion, we cover how to retrieve credentials from Azure Key Vault, how to retrieve data from a web page, and how to bring everything together in a message submitted to HVE.
HVE and ECS are two competing Microsoft Cloud Email Services. At least, they seem to compete. In reality, HVE and ECS serve different target audiences. HVE is all about internal email services for apps and devices while ECS is for high volume external mailings like customer newsletters. We tested both services by sending subscription reminder notifications to Office 365 for IT Pros readers.
