Microsoft Rushes High-Volume Email to General Availability

HVE Goes GA.

Almost two years after it first previewed, Microsoft is making the High-Volume Email (HVE) solution generally available in March 2026. HVE runs on a pay-as-you-go basis, but Microsoft won’t start charging tenants for sending email until May 2026. Two months should be enough for people to decide if they want to use HVE for internal communications as it has no ability to send external email.

How to Send Outlook Newsletters with Email Communication Services

Outlook Newsletters and Azure ECS

Outlook Newsletters are intended for internal communications, at least for the preview. It’s possible to take the HTML for a newsletter and send it with Azure Email Communication Services (ECS), the PAYG service for bulk email. It sounds like a good way to use Outlook Newsletters to share information with customers and other external recipients. Some manual intervention makes everything works. It would be great if Microsoft tweaked Outlook to remove the rough edges.

Comparing Microsoft Cloud Email Services

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.
