Business Case of Moving Back from Microsoft 365
A large number of organizations have chosen to move from their on-premise Microsoft Exchange to Microsoft 365 (formerly Office 365). The migration path is always challenging but once migrated, many organizations continue to get good service and more organizations continue to move to the cloud.

There is a definite case for some organizations to move back to an on-premise Microsoft exchange either totally or in a hybrid configuration where on-premise Exchange coexists with the Microsoft 365 cloud. This blog mentions few of them.
Reverse Migration Factors
On-Premise Microsoft exchange and related suite of Microsoft Enterprise applications have developed a large ecosystem of third party applications based on Exchange. Many organizations were using quite a few of them and are unable to find the right choice with Microsoft 365.
The Cloud Experience
Some organizations moved to Microsoft 365 because it offered a cloud experience; dashboards for all types of users, APIs, best security practices etc.
There are newer applications out there (Hosting Controller is one) which will transform an on-premise Microsoft Exchange into a ‘Private Cloud’, which means having an experience very similar to Microsoft 365. All users have their feature rich dashboards. Admins have their separate dashboards. All common features are available as restful APIs. In fact, the APIs enable a level of DevOps automation difficult to achieve through the online version.
Regulatory and Security Requirements
Many government organizations especially the more sensitive ones like military are apprehensive of moving their data into a public cloud. Most others have regulatory restrictions of actually keeping their data within geographical boundaries. Such requirements may not have been there when initial migration to the cloud was proposed.
They have a binding case of bringing the mails and data back into their own data centers.
The Online Application Suite
Some organizations moved their emails and data to the cloud because they wanted some software applications e.g. Skype for business for their users. Hybrid technologies now enable users to keep their email and data along with Microsoft exchange in their own data centers and still subscribe to online applications for the same users. Admins can choose which applications run on-premise and which ones are activated in the cloud. This at times also comes with substantial cost savings.
User and Device CALS
An on-premise Microsoft Exchange along with its related applications like SharePoint requires a purchased license.
On-Premise exchange costs are based on hardware, Exchange server and requires CALs for user or devices accessing the server.
Online costs are per user and are different for packages which raise quickly. Organizations with larger number of users.
While online storage is charged per mailbox or other units, the on-premise storage is as much as you want to put. Some organizations may find that they are restricted by the limited storage offered in Microsoft online unless they are willing to pay substantially higher. Organizations may want to store the data in multiple copies instead of one.
Hybrid Cloud Technologies
Hosting Controller is a Microsoft 365 Hybrid Cloud Controller. Hybrid cloud technologies, enable users to easily move between their on-premise Exchange servers and Microsoft 365 in different configuration.

Once in place, they offer a near similar cloud experience for their on-premise exchange as well. Admins can drag a mailbox from one place and drop it in the other and the user account and its related mail data is moved. This could be from on-premise to the cloud or vice versa.
If for any of the reasons mentioned above or any other reason, you find that moving totally back to the on-premise is a better idea, or a coexistence between your on-premise Exchange and Microsoft 365 public cloud is a better idea, you are one of those 98% organizations who think Hybrid Clouds offer the most flexibility.
