In the previous articles, we have already discussed how to migrate Exchange data from EDB to PST file. There are many organizations today switching from Exchange Server to Office 365, a cloud-based version of Microsoft Office.

Additionally, it reduces the overall cost required to run and maintain the Exchange Server edition.

Exchange to Office 365 Migration. Why?

Microsoft Exchange Server is a great way to manage, store, and distribute the company’s emails. It also contains various useful features that enable users to store contact details, schedules & tasks, and share them with one other. But we know that the on-premise server has become old technology. The long-term success of any business simply depends on making the right decisions. Choosing the right cloud solution for an organization is one of the most important decisions one has to make.


If your organization is still using Exchange Server, it is the right time to plan to switch to Office 365. It has been a number of years since Microsoft launched Office 365. It can help your employees work together more efficiently than ever. Microsoft Office 365 is not just a tool, it is actually a new way of working. There are several reasons why small businesses and large enterprises should consider using Office 365.

Office 365 Benefits

  • It is easy to migrate to Office 365 from any on-premise solution like Exchange Server. If you perfectly plan the migration and execute it properly, it works so fine.

  • Office 365 works on a subscription basis so it is completely scalable. You can pay for the service as a monthly subscription. No need to pay a big amount in advance.
  • Being a cloud-based service, Office 365 allows users to work from anywhere on any device. This means users are no longer needed to sit on the desk to access the organization’s data. Since they can work on mobiles, tablets, and laptops from anywhere, they can be more productive than before.
  • By switching to Office 365, you can simply reduce the cost you are spending on Microsoft Exchange Server.
  • With Office 365, you know how much each user will cost. Since organizations are primarily concerned about cybersecurity, Office 365 supports features like data loss prevention, mobile device management, email encryption, etc.

Exchange to Office 365 Migration. Why?

Above we have discussed Office 365 benefits. Now let us learn how to migrate data from Exchange to Office 365. Some easy solutions I would like to share here that will help you in Exchange to Office 365 migration:


  • Exchange Hybrid Migration
  • Cutover Migration
  • Migration by PST

Before you use any of these solutions for Exchange to Office 365 migration, make sure that Exchange Server, the source environment you are migrating from, is in a good state. If you using Exchange Server 2010 or any later version and it is a part of Active Directory, the Exchange Hybrid Migration will definitely work for you.

Exchange Hybrid Migration

The Exchange Hybrid Migration solution allows users to migrate on-premises mailboxes to on-site. It is commonly used for Exchange to Office 365 migration. Exchange Hybrid creates a relationship between the on-premises Exchange Server and Exchange Online. Using this, you can migrate the existing mailboxes from Exchange Server to Office 365.


If you have a lot of data to migrate and the process may take a lot of time, this manual solution is extremely useful for you. Exchange Hybrid is the only solution that can easily migrate over 2000 mailboxes. In fact, it is strongly recommended to use Hybrid if there are 150 mailboxes or more to migrate.

Cutover Migration

If you are one of those users who want to migrate to the whole environment at a time, the Cutover Migration best fits your needs. This migration solution is helpful for business customers running Exchange Server 2003 or any later version and can be used to migrate less than 2000 mailboxes. The Cutover Migration solution specifically works for users who are using Exchange Autodiscover service against Exchange 2007 or any later version. This will help them determine the mailboxes available for migration.


But if you are running Exchange 2003 as an on-premise server, you need to enter the RPC (Remote Procedure Call) proxy addresses manually in order to access the Exchange mailboxes to migrate. This option is available for both Office 365 Enterprise and Business customers.

Migration by PST

There are so many articles on the Internet that contain more information on the manual solutions I have discussed above. There is one more way by which you can migrate the data from Exchange to Office 365. All you need to use is Office 365 PST Import Service. First, you need to export Exchange mailbox to Outlook PST file. And then, you can upload the PST file to Office 365. This process will require an administrator to do perform manual tasks that include creating a new Office 365 environment.


The above solutions for Exchange to Office 365 migration are highly effective, and also they do not require any 3rd party software. Unluckily, each of the migration solutions has some drawbacks:


  • The Exchange Hybrid migration can take a lot of time and manual effort. You are likely to encounter many difficulties during this process.
  • A cutover migration is something like an all-or-nothing solution, and also it is not recommended for more than 150 mailboxes at a time. In addition, it does not allow Exchange and Office 365 coexistence.
  • If you are trying Office 365 Import Service, keep in mind that the migration process will neither be automatic nor reliable. It is only helpful in a case when there is not much data to migrate. Do not forget that you need to recreate the Exchange environment from scratch in Office 365.
