When preparing for the MS-203 Microsoft 365 Messaging exam, it is crucial to understand how to configure migration endpoints. This process allows you to migrate email from one platform, such as Exchange Online, to another, such as Microsoft 365. Whether you want to move all your mailboxes at once or stagger them in smaller batches, understanding how to configure migration endpoints is an essential task.
Migration endpoints are management objects that describe the settings and credentials needed to connect the source environment from which you’re migrating. They come in three types: Exchange Remote endpoints, IMAP endpoints, and Exchange Hybrid endpoints.
To configure migration endpoints, you must first have Exchange Admin Center (EAC) or Exchange Management Shell (EMS) access.
Exchange Remote endpoints
To configure Exchange Remote endpoints, you need the following:
- Login details for the on-premise Exchange Server.
- Verify admin access to the Exchange Server.
Then follow these steps:
- From Exchange Admin Center (EAC), go to ‘recipients > migration > more > migration endpoints > New+’.
- Choose ‘Exchange Remote’.
- On the ‘new migration endpoint’ page, fill in the details. For the endpoint type, choose Exchange Remote move.
- Fill in the ‘Exchange server’ (on-premises server FQDN) and ‘RPC proxy server’ (Outlook Anywhere server settings) boxes.
- Provide the account credentials with the necessary permissions on the ‘new migration endpoint’ page.
- Save the endpoint and test the connectivity to confirm.
IMAP endpoints
For IMAP endpoints, the minimum requirement is to have the login details for the IMAP mailbox. Here are the steps:
- From EAC, go to ‘recipients > migration > more > migration endpoints > New+’.
- Choose ‘IMAP’.
- On the ‘new migration endpoint’ page, type the IMAP server address.
- Specify the connection settings and security compliance according to your organization’s policies.
- Save the details, and test the connectivity to confirm.
Exchange Hybrid endpoints
For Exchange Hybrid endpoints, it requires
- A functioning Exchange Hybrid deployment.
- Verify the connectivity and permission settings between the environments.
To set up a Hybrid endpoint:
- From Exchange Admin Center (EAC), go to ‘Office 365 > email migration > More > Migration endpoints > New+’.
- Choose ‘Hybrid migration endpoint (Exchange 2010 and later)’.
- On the ‘new migration endpoint’ page, fill in the details: on-premises server’s FQDN and Outlook Anywhere settings (RPC Proxy Server).
- Save the endpoint and validate the settings with a connectivity test.
The table below summarizes the three types of migration endpoints:
| Type of Endpoint | Requirements | Tools Used |
|---|---|---|
| Exchange Remote | Login for Exchange server, Admin access | EAC |
| IMAP | Login for IMAP mailbox | EAC |
| Exchange Hybrid | Functioning Hybrid deployment, Permission settings | EAC |
Configuring migration endpoints offers you a streamlined and efficient way to move email data to another platform. By understanding this process, you will be better prepared for the MS-203 Microsoft 365 Messaging exam. It’s worth noting that your organization’s network status, security protocols, and overall user mailbox size could affect the migration process, so plan carefully and allow ample time for completion.

- a) IMAP
- b) POP3
- c) HTTP
- d) MAPI
Answer: a) IMAP, c) HTTP, d) MAPI
Explanation: In Microsoft 365, IMAP, HTTP and MAPI can be used as migration endpoints for different migration scenarios.
True or False: It is not common to establish multiple migration endpoints for a single organization.
- True
- False
Answer: False
Explanation: It is quite common to establish multiple migration endpoints depending on the requirements of the organization. This could be due to different sources, different connection settings or throttling policies.
Where can you manage migration endpoints in Microsoft 365?
- a) The Exchange Admin Center
- b) The Office 365 Admin Center
- c) Azure Active Directory
- d) SharePoint Admin Center
Answer: a) The Exchange Admin Center
Explanation: Migration endpoints are managed within the Exchange Admin Center in Microsoft
True or False: You cannot remove a migration endpoint once it has been set up.
- True
- False
Answer: False
Explanation: A migration endpoint can be removed if it’s no longer required. This is done using the ‘Remove-MigrationEndpoint’ cmdlet in Exchange Online PowerShell or via the Exchange admin center.
What is the maximum number of migration endpoints that you can create per migration type in Microsoft Exchange Online?
- a) 10
- b) 100
- c) 1000

Answer: a) 10
Explanation: Microsoft Exchange Online allows for up to 10 migration endpoints per migration type.
True or False: Migration batch is a concept related to migration endpoints.
- True
- False
Answer: True
Explanation: A migration batch is indeed related to migration endpoints. It is a collection of one or more mailboxes, contacts, or distribution groups in a migration endpoint.
