Create Migration Endpoint in Microsoft 365

The Hybrid Configuration Wizard couldn’t create the migration endpoint. Without that, you cannot migrate mailboxes to Exchange Online in Microsoft 365. So, let’s create it manually and verify that the migration endpoint is successfully created. In this article, you will learn how to create a new migration endpoint in Microsoft 365.

Migration Endpoints in Exchange Online

Migration endpoints are management objects that describe the remote server and the connections that can be associated with one or more batches.

They store details about the remote server, login credentials, and settings that control how fast data is moved. Once set up, these endpoints can be used for one or more migration jobs.

Step 1. Get MRS proxy endpoint

Before you start and create a migration endpoint in Exchange Online, you must enable and get the MRS Proxy endpoint URL from the on-premises Exchange Server.

1. Sign in to the Exchange Server on-premises
2. Start Exchange admin center
3. Click on Servers > virtual directories
4. Double-click on EWS (Default Web Site)

5. Copy the external URL hostname
6. Ensure that the Enable MRS Proxy endpoint is checked

You can create a new migration endpoint in Exchange Online (Microsoft 365) using the Exchange Admin Center or Exchange Online PowerShell.
