By Silver Hawak posted Sat October 09, 2021 10:55 AM


Microsoft Office 365 cloud solution is not a surprising product due to its widespread use in businesses around the world. However, due to the numerous issues that come with Office 365 migration, not all administrators are enthusiastic about it. Furthermore, not every organization has the same migration requirements. For example, business units with limited time and resources do not prefer to migrate all their mailboxes at once. Other enterprises who would like to retain some data in their local environment opt for hybrid migration, and so on. These migrations can be carried out using either the native built-in methods from the Microsoft Exchange admin center (EAC) or PowerShell commands. Nevertheless, manual methods have limitations that make them unsuitable for large-scale and secure migration operations. In this article, we'll go over the 5 different methods for migrating from Microsoft Exchange to Office 365, so you can choose the one that's right for you. In addition, we introduce you to EdbMails, a safe and quick tool for performing the migration without difficulty.

What are the various methods for migrating Exchange mailboxes to Office 365?

  • Exchange to Office 365 Cutover migration
  • Exchange to Office 365 Staged migration
  • Exchange to Office 365 Hybrid migration
  • Migration using an IMAP enabled server
  • Exchange to Office 365 migration using PST files.

Shortcomings of the native methods for performing Exchange to Office 365 migration

Before delving into the above-mentioned migration techniques, it is important to first understand the limitations of using native tools to perform the migration.

  • A cutover migration is not appropriate for more than 150 mailboxes.
  • A staged migration is only relevant for Exchange 2003 or Exchange 2007 systems.
  • The native methods have size limitations when migrating public folders, and downtime is a common issue.
  • The manual method is also limited by Exchange and Office 365 throttling.
  • The hybrid migration is time-consuming and necessitates extensive planning.
  • Native methods do not support filtering to selectively migrate the required contents to the target.


EdbMails is an all-in-one solution for successfully migrating from Exchange to Office 365.

Now that we've established the limitations of the native Exchange to Office 365 migration methods, let's take a look at the 5 ways EdbMails can solve the aforementioned issues and ensure a successful migration.
