Why Transfer Amazon WorkMail Data to Microsoft 365?

As you probably know, Amazon WorkMail is still growing in terms of user convenience. On the other hand, Office 365 comes with the MS Office package, which covers 95% of the users in the world. This makes it easy for all users dealing with large businesses to complete all tasks efficiently. Furthermore, with the help of O365, one can manage their data with utmost security.

Additionally, you will agree that AWS WorkMail requires more support than Office 365 Management. Where Amazon WorkMail offers only a 25MB email size limit for sending or receiving messages, Office 365 users get 150MB in total.

There are even more useful features than AWS that Microsoft 365 provides for better efficiency and increased productivity.

How to Migrate AWS WorkMail to Office 365 Manually?

There are many options for you. Let’s discuss them one by one. Starting with the most obvious direct email forwarding.

  • Step 1. Log in to AWS webmail.
  • Step 2. Select an email.
  • Step 3. Press the forward icon.
  • Step 4. Type your M365 email address in the To field and press Enter.
  • Step 5. Repeat for all other messages.

Another option is using email clients.

  • Step 1. Choose an email client (Outlook, Thunderbird, etc.).
  • Step 2. Add your AWS and O365 accounts one by one.
  • Step 3. Grab a bunch of emails from AWS and drop them in O365.

However, you might face some issues with the methods, so check out how to solve these issues.

Problems with the Manual Transfer Process

When you try to shift AWS WorkMail to M365 on your own, you will encounter these avoidable problems:

One major issue is that Microsoft’s spam filter treats incoming emails from AWS WorkMail as spam. This happens prominently to those who use the forwarding method; here, the email never arrives in the intended location, but rather goes to the trash and eventually gets permanently deleted. An easy way to bypass this error is to whitelist the email in Outlook 365.

The Email client method might sound pretty simple on paper, but when you go about to actually perform the steps, you realize the sheer amount of effort required to get the ball rolling. Setting up multiple accounts on an email client is confusing, especially for novice users. Another issue is that you can’t predict how much of the transfer is done, plus there are no end-of-migration reports that tell you the gist of the project.

Instead, I have a better option for you to make sure you try it.
