Edbmails Solution To Merge Two Office 365 Accounts

Can I merge two Office 365 accounts?” is a question that many IT administrators around the world have, when dealing with circumstances that necessitate the merging of two Office 365 tenants. When done manually, the process necessitates a great deal of meticulous planning and preparation in order to avoid any interruptions in the mail flow; yet, it can also result in significant overhead and take a long time. This is why merging Office 365 accounts or performing Office 365 tenant to tenant migration is generally recommended using a professional third-party application like EdbMails Office 365 migration tool.

Why is merging two Office 365 accounts needed?

 Let's look at the various circumstances why merging two Office 365 accounts can be necessary:

  1. Business and personal accounts: If you have a business account with work email that you use to access Office 365 tools, SharePoint, Microsoft Teams and so on and also have a personal account, you'll need to merge your Office 365 accounts if you ever want to combine the two.
  2. Mergers and Acquisitions (M&A): If a business firm acquires another firm, merging Office 365 accounts is the logical solution. Consider the following scenario: A business unit XYZ has acquired the smaller firm ABC, and both organisations have their own Office 365 tenants as depicted. In this situation, all the mailboxes from the source xyz Office 365 tenancy must be migrated to the target abc Office 365 tenant without disrupting the mail flow.
Source Tenant Target Tenant
Domain xyz.com abc.com
Office 365 domain xyz.onmicrosoft.com abc.onmicrosoft.com


  1. Data localization and legal issues: Every organization has its own set of compliance rules that must be followed. When a company operates in various countries, it may be challenging to comply with the local regulations and can result in hefty fines if violated. This necessitates that the user's Office 365 services be hosted on the servers in the specific country. For example, in order to comply with laws such as GDPR, a European user's mailbox hosted on a US server must be migrated to European servers.

What are the challenges of merging two Office 365 tenants?

Whatever the reason is, if you want to merge two Office 365 accounts, you should be aware that Office 365 doesn't permit direct tenant-to-tenant migration using the native method or from the Exchange admin center (EAC)

One possible option is to build up a Hybrid Exchange Server and migrate all mails from the source tenancy to it, and then you can migrate all mailboxes from Hybrid Exchange Server to the target Office 365 tenant. This necessitates disconnecting the tenant's domains and performing migrations to intermediate units before finally moving to the destination. When migrating to an intermediate stage, it is possible that not all migrations are supported. For instance, a permission or a calendar entry that was migrated to the Hybrid Exchange unit may not be migrated during the final move, leaving bits and pieces of data scattered around.
