Exchange Online and On-Premises Exchange?

What is Microsoft Exchange Online?

When it comes to commercial communication, emails have always been at the forefront. And for email service, Microsoft Exchange is likely the most widely used tool. Although previously, this was housed on an On-Premise server, the advent of Exchange Online overruled the server rendering it unnecessary.

Let’s consider a few differences to determine whether you should buy On-Premises Exchange or Exchange Online.


Exchange Online is known to have a customizable cost. As a business, you have to purchase licenses for users. And licenses can be purchased as a solo Exchange Online License or accessed through Microsoft 365 subscriptions.

On the other hand, the initial investment of On-Premise is larger. With Exchange On-Premise, you are in charge of the server and all hardware server maintenance. Although the initial investment is expensive, if you keep the server for about 10 years and upgrade it every 3 years, it can be a less expensive option.


When it comes to the most recent features and software, Exchange Online is the best option. You’ll always have access to the newest technology when used with Microsoft 365. With Microsoft, you’ll enjoy automatic security flaws and upgrades.

As for On-Premise Exchange, you’ll have to update it manually.


Each user only has 50GB of mailbox storage under the Exchange Online basic plan. However, On-Premise allows you to customize mailbox storage to fit your needs. The only factor limiting the maximum mailbox is the storage capacity of the server’s hard disk.



Microsoft manages all Exchange Online servers, employing about 3,500 security professionals. This Exchange Online Protection is no doubt a significant investment.

When you use Exchange On-Premise, however, you’re in charge of the full maintenance of the server.
