What is Microsoft Exchange Server?

There are many applications for using mail servers ,  such as  Microsoft Exchange Server or Office 365 . The choice of which application your organization uses obviously depends on your needs.   Here  we  discuss what Microsoft Exchange Server is and what   are the differences  between the Microsoft Exchange Server  and  Microsoft Office 365. 

What is the Microsoft Exchange Server? 

The Microsoft Exchange Server is an application used to manage and send emails, messages and calendars. The Exchange Server can be hosted both on-premise and in the Cloud.  

Microsoft Exchange Server has several functions such as managing: 

  • Emails  
  • Contacts (address book)  
  • Agendas  
  • Tasks  
  • Notes  


Microsoft Exchange Server is often seen as the on-premise counterpart of cloud-hosted Office 365.   

Microsoft is trying to get many organizations to migrate to Cloud solutions such as Office 365. However, not every organization is ready to move to the Cloud and in many cases it is not necessary for a company. In addition, it is not necessarily cheaper for every company to migrate to the Cloud.  

For these organizations, an on-premise solution such as the Microsoft Exchange Server can still be an ideal solution! 

What are the differences between Microsoft Exchange Server and Office 365? 

There are a number of major differences between the Microsoft Exchange Server and Office 365.  

We have listed these differences for you below:  

1. Storage of data in-house

The biggest difference with Office 365 is where your information is stored. With Exchange on-premise, the information is stored on its own servers. This may be a specific requirement for some companies, for example if they are dealing with sensitive information and/or legislation and regulations.  

2. Maintenance

With the Exchange on-premise solution you have to carry out the maintenance yourself. This means that you will have to install the updates and make changes yourself.  

If you use Office 365, these updates are performed automatically by Microsoft. This means you always have the latest version. However, keep in mind that this can sometimes cause problems with links to other software. 

3. Costs

With the Microsoft Exchange Server, you incur one-time purchase costs. While with Office 365 you enter into a subscription service. This means that you pay monthly for the use of the software. With Office 365 you also receive other Office products such as Excel, PowerPoint and Word included in the service.  

However, it is good to keep in mind that when using on-premise solutions there are also costs associated with the hardware. The hardware is of course where the Exchange solution is installed, and it must be replaced every few years. You will also need to purchase newer versions for the Exchange Server again.   

4. Protection and Backups  

With the Microsoft Exchange Server, you are responsible for detecting and solving any problems. This means that you actively protect your systems and platforms against possible threats yourself or you have to hire professionals for this. So make sure you make regular backups in case of a problem. 

What versions of Microsoft Exchange Server are there? 

There are different versions of the Microsoft Exchange Server available: 

  • Exchange Server 2019  
  • Exchange Server 2016  
  • Exchange Server 2013  

Each of these versions has the following types of licenses:  

  • Standard  
  • Enterprise  
  • User  CALs
  • Device  CALs    

These licenses are also available pre-owned. This allows you to save a lot of money for the exact same software!
