Exchange active sync mail server

A great topic!

ActiveSync is a protocol used by Microsoft Exchange Server to synchronize email, contacts, calendar, and other data between a mobile device and the Exchange Server. If you need to exchange ActiveSync mail servers, you'll need to set up a new connection between the two servers. Here's a step-by-step guide to help you do so:

Prerequisites:

  1. Both mail servers must be running Exchange Server 2010 or later.
  2. The new mail server must have the same or higher version of Exchange Server as the original mail server.
  3. You'll need to have administrative access to both mail servers.

Step 1: Prepare the new mail server

  1. Install and configure Exchange Server on the new mail server.
  2. Create a new Active Directory forest or domain if you're moving to a new domain.
  3. Set up the new mail server's DNS records to point to the new server's IP address.

Step 2: Migrate mailboxes

  1. Use the Exchange Server's built-in migration tool, the Exchange Migration Wizard, to migrate mailboxes from the original mail server to the new mail server.
  2. Alternatively, you can use third-party migration tools, such as BitTitan's MigrationWiz or Quest's Exchange Migration Manager.

Step 3: Configure ActiveSync

  1. On the new mail server, go to the Exchange Admin Center (EAC) and navigate to Mail flow > Connectors.
  2. Click New and select Microsoft Exchange as the connector type.
  3. Enter the FQDN of the original mail server and the authentication credentials.
  4. Set the Use SSL/TLS option to Yes.
  5. Click Save to create the connector.

Step 4: Configure mobile devices

  1. On each mobile device, go to the device's settings and select Accounts or Email.
  2. Select the Exchange account and click Edit.
  3. Enter the new mail server's FQDN and authentication credentials.
  4. Save the changes.

Step 5: Verify connectivity

  1. Test the ActiveSync connection by sending an email from a mobile device to a mailbox on the new mail server.
  2. Verify that the email is delivered successfully and that the mailbox is synchronized correctly.

Additional considerations:

  1. Make sure to update the DNS records to point to the new mail server's IP address.
  2. Update any firewall rules or network configurations to allow traffic between the two mail servers.
  3. Consider implementing a load balancer or high availability solution to ensure the new mail server can handle the increased traffic.
  4. Test the new mail server's performance and scalability to ensure it can handle the workload.

By following these steps, you should be able to successfully exchange ActiveSync mail servers and migrate your email, contacts, and calendar data to the new server.
