How to make changes to Microsoft 365 Entra Admin Center so BitTitan MigrationWiz can migrate emails into Microsoft 365 Exchange Online

Introduction

This is the 5th step in our complete guide on how to migrate your emails to Microsoft 365 Exchange Online. In the previous step we created user accounts for all the email addresses we want to migrate to Microsoft 365 Exchange Online. This means we also have mailboxes for our email addresses but the mailboxes are empty and they are not live either.

Since December 2022 Microsoft 365 has used somrthing called Modern Authentication to make Microsoft accounts more secure. When we come to migrating all of your existing emails into Microsoft 365 Exchange Online we will be using a 3rd party service called MigrationWiz. In order for MigrationWiz to be able to access the new mailboxes in Microsoft 365 and migrate emails across we need to make changes in the Microsoft 365 Entra Admin Center. Entra is the new name for Azure Active Directory..

1. In the Microsoft 365 Admin center click the 3 horizontal lines in the top left corner

2. Click Show all and then click Identity.

4. Click Manage security defaults.

5. Change Security defaults from Enabled (recommended) to Disabled (not recommended).

Note: this is just a temporary measure and once the migration is complete we will turn the security defaults back to enabled.
