For years, organizations operating on-premises mail management have hesitated to adopt the cloud for a few simple reasons. Lack of a proper mass mail functionality in O365 was one of them. With the introduction of Exchange Online High Volume Email, this problem is now over.

Administrators can now automate payroll notifications, IT service alerts, or device-driven pings from printers and scanners.

Exchange Online is an excellent peer-to-peer email system with state-of-the-art protection systems to prevent abuse. However, it was these safety features that resulted in a bottleneck whenever admins had to make an organization-wide announcement.

The constant confusion about whether to use a Shared Mailbox vs a Distribution List, both of which are not apt for such scenarios, meant admins had to maintain a proper on-premises presence.

Now with the introduction of HVE, this is no longer the case, so you can stop maintaining hybrid systems and end the expensive third-party mass mailing subscriptions.

Let us start by understanding what exactly this new service is.

What is Exchange Online High Volume Email?

Borrowing from Microsoft’s official announcement, HVE brings a brand new tenant-native way for apps and devices to broadcast emails en masse.

No separate installation or update is required; it is built into the service directly. Admins no longer have to worry about simple announcements impacting the health of their Exchange Online Environment, only when it comes to internal recipients.

One major limitation of HVE is that it can’t send out messages to external recipients. However, this in no way puts its abilities into question for internal communication, so let’s see where all you can use it and how exactly to set it up.

Where and How to Use Exchange Online HVE?

High Volume Email is beneficial in many different day-to-day scenarios, like:

  • Systems where HR announces company-wide payroll updates.
  • Monitoring IT resources and pinging alerts to relevant parties.
  • Performing business app messaging to many people at once.
  • Allowing devices like printers to autonomously update availability status.
  • Help in notifying of any major security updates quickly.

There are no separate settings to toggle each of these requests; there is a single universal portal found inside your M365 admin center. Note that it should be purchased separately for the settings to become visible inside the portal.

Transition to Cloud and Use Exchange Online High Volume Email

With Exchange Server alternatives popping up left and right, O365 still remains the king only because it is a Microsoft service. You can’t use this brand new service if you keep your system on-premises. Now it has become essential to make the move.

Frequently Asked Questions

Q: Is Exchange Online HVE available for free?

No, it is a paid add-on service. Its cost will be calculated separately in your regular billing cycle on top of the default M365 license that you subscribe to.

Q: How to calculate the HVE usage price?

You can make a pretty solid estimation of how much it will cost by following the official Microsoft pricing statement. Which is as follows:

  • $42 per 1,000,000 recipients
  • Equivalent to $0.000042 per recipient

You can clearly see that the only variable is the number of expanded recipients. So, for example, if your recipient list has 10,000 people, Microsoft will charge you 42 cents.

Q: Who can set up High Volume Email in Exchange Online?

Being a highly sensitive setting, only the personnel with the right permissions are allowed to set up an HVE. It includes:

  • Exchange Administrators
  • Global Administrators
  • Or users assigned appropriate mail flow and role management permissions

Q: Can anyone be a part of the Exchange Online High Volume Email?

No, the HVE is strictly for internal communication only, so only the users part of your O365 tenant can be added as a recipient; no outside parties are allowed.

Q: Who should get the new High Volume Email licensing in Exchange Online?

Ask yourself whether you have to regularly make organization-wide announcements. It could include changes in appointments of C-suite executives, new physical devices, policy updates, etc. If the answer is yes, then HVE is a must.

Q: Does HVE completely replace legacy mass mail systems?

No, there is one use case where HVE is yet to work, which is external mail. Legacy systems can include an email ID not part of your organization. Microsoft’s High Volume Emails’ GA version does not have this feature as of now.
