How to migrate AWS Workmail to Office 365 (Microsoft 365)?

EdbMails software for AWS Workmail

Amazon, which began as a modest e-commerce service, has now spread its wings and made its presence felt in a multitude of sectors, including cloud services, books and accessories, digital goods, Alexa, entertainment, and even groceries. Its primary focus is cloud hosting and providing business solutions, similar to Microsoft, Google, and Apple. Amazon Workmail, for example, is used as a web email service by many businesses. However, due to many reasons users want to switch from AWS Workmail to Office 365. For instance, Microsoft has a plethora of useful collaboration apps and features such as Microsoft Word, Excel, SharePoint, and Teams, to name a few which are included in the same package. With Office 365, it is much easier to have everything under one roof rather than searching for bits and pieces all over the place. Users of Microsoft Teams can easily make a call, leave a message, start a web conference, and catch up with colleagues. Office 365 also allows you to keep your old domain for sending and receiving emails. You can transfer mailboxes from AWS Workmail to Office 365 using the EdbMails IMAP migration software. It is best suited for both small and large businesses and makes migration easier thanks to its graphical user interface. The fact that EdbMails automates the entire process with minimal user involvement is one of its enticing characteristics. It gives you the ability to directly do a migration without any complications by connecting to the source AWS Workmail and the target Office 365.

How to migrate from AWS Workspace to Office 365?

You can perform the migration with the following two methods.

Migrate AWS Workspace to Office 365 from the Exchange admin center
Migrate AWS to O365 with EdbMails IMAP migration

Steps to migrate AWS Workspace to Office 365 from the EAC

Step 1: Ensure that you are having administrator access on AWS and Office 365
Step 2: Create user mailboxes on the target Office 365 tenant
Step 3: Add email domain from the AWS Workmail to Microsoft 365
Step 4: Make a note of the IMAP connection details from the source account.
Step 5: Create a list of mailboxes to migrate to O365 in a .CSV file
Step 6: Create a migration endpoint and migration batch
Step 6: Update the MX record to route the email to Microsoft 365

Keep in mind that this is a manual method which must be carried out using an IMAP connection from Microsoft's admin center. After you have created the .CSV file, you must manually upload it to the EAC and allow Microsoft to verify it. When the migration operation is finished, the status changes to Synced, and you can delete the migration batch and decommission your old email environment. This may be time-consuming and inefficient, with no tangible results.
