Difference between Hosted Exchange vs Office 365

A comparison showing the difference between Microsoft 365 and Hosted Exchange email platforms.

Exchange or Office 365

There are now two solid cloud based email solutions from Microsoft for small business and large organizations. Do you choose Office 365 or Hosted Exchange for your business email, productivity and collaboration suite? While Office 365 offers a complete email solution with updates to Microsoft Office Suite included with most plans. Either email system will allow full syncronization of email and calendars on email clients. Exchange still offers slightly better email reliability and greater customization to allow for a configuration that suits your organization’s needs. Although every Microsoft Office 365 plan includes cloud email that is actually running on Microsoft Exchange server. The means either system actually uses the same email servers. A big difference here, is one is hosted by a hosting provider and the other is hosted by Microsoft. Both Office 365 and Hosted Exchange are a cloud solution that evades the need of having servers on premises.

We can also migrate any existing on premise exchange to Exchange online, as well as upgrade from previous Exchange versions including active directory.
