On-premise Exchange vs. Office 365 – Are you ready to transition?

On-premise Exchange vs. Office 365 – Are you ready to transition?


In today’s cloud driven world, organizations are continually faced with the decision to keep their email solution in-house, or utilize a public cloud solution like Office 365. The standard for years has been an on-premise Microsoft Exchange server. This solution still works for many deployment scenarios, but moving your email and calendar solutions to Office 365 is a growing trend. In a recent study by Barracuda, over 63% of respondents indicated they are currently using Office 365.

So, how do we choose either an on-premise Exchange solution or Office 365? Let’s look at some of the key reasons to use each.

On-Premise Exchange:

  • With your email hosted onsite, your company has complete control of the environment. This can be useful for things like configuring your backup solution, managing the size of user mailboxes, and how you want mail to flow through your email security solution.
  • Your IT department may already have engineers on staff that are experts with your existing Exchange deployment. With that said, moving to Office 365 may require you provide training for your current staff.
  • Transitioning to Office 365 requires planning and training for your user community that needs to be taken into consideration during deployment.

Office 365:

  • With Office 365, your IT department no longer has to worry about performing security updates or Exchange Cumulative Updates. All of that is done automatically by Microsoft, without any downtime required. This also allows any new features to be utilized right away by your employees.
  • Hosting your email in the cloud means you no longer need physical equipment used previously. This means lower costs for purchasing the actual servers, switches, etc., as well as removing support contracts for that equipment. Add that to the lowered power consumption, and your IT costs will decrease.
  • Physical equipment also ages. Traditionally, the guidance is to replace physical hardware every 5 years or so. With Office 365, this requirement no longer exists.
  • Once you have migrated to Office 365, the ease of management increases. Your IT department requires less engineers to maintain your email, and lower level engineers can perform tasks that used to require more advanced knowledge of the Exchange setup.

The transition to Office 365 is an undertaking for any business, but provides many benefits. In the long run you will lower your IT costs and the demands placed on your engineering team. The need to replace your outdated equipment reduces drastically. If the transition seems daunting, then consider having a managed service provider help you throughout the process. With the right partner by your side, you will have better support training your IT staff and your end users. Although this is a large transition, there are many ways to make it easier on your organization.
