      Businesses that have the need to be compliant with regulations such as GDPR or HIPAA would benefit from the data retention, audit log, and eDiscovery tools provided by Exchange. While both solutions are adequate, shared mailboxes in Office 365 generally lack the tools for large-scale compliance management.

4. Planning a migration from Office 365 Shared mailbox to Exchange

   • Ensure that you enable the shared mailboxes and make them available in Office 365 admin center.
   • Create and enable shared mailboxes on the Exchange server
   • Determine whether you want to migrate the source Shared mailboxes to the target primary or Shared mailboxes.
   • Determine whether you want to move everything at once or in stages.
   • Check your internet connection speed and network configuration.
   • Communicate the migration plan and the changes to your end users.
   • Perform a test Office 365 migration before you start the actual one.

5. Pre-migration activities for Shared mailbox to Exchange migration

   Before starting, confirm the shared mailbox you want to migrate is enabled and visible in the Office 365 admin center. You'll also need a Global Admin account for Auto Registration of the EdbMails application on Entra ID (Azure Active Directory); if you're using Manual Registration instead, a user account with full access permissions is enough. Finally, confirm your network and bandwidth can handle the migration - see network and migration planning and performance factors and best practices for Office 365 to Exchange migrations.

   On the target Exchange server side

   Step 1: Confirm the Exchange server meets setup requirements

   Check the network, hardware, and operating system requirements for your target Exchange version: Exchange 2016 requirements | Exchange 2019 requirements.

   Step 2: Prepare Active Directory and the target environment

   Prepare the Active Directory forest and domains for the new Exchange version, then install Exchange 2016 or install Exchange 2019. Once installed, configure Send and Receive connectors, accepted domains, internal and external URLs, and SSL certificates so the server can send and receive mail from outside the organization.

   Step 3: Create shared mailboxes on the Exchange server

   EdbMails can automatically create target mailboxes during migration, including shared mailboxes, so this step can be skipped if you'd rather let the tool handle it. To create them manually instead, follow Microsoft's steps to create mailboxes in Exchange server.

   Step 4: Set impersonation rights and throttling limits

   If you're connecting with a Global Admin account, set impersonation rights so it can access the shared mailboxes being migrated. Also check EWS throttling settings and message size limits on the target server, since shared mailboxes with large volumes of historical mail can hit these limits during transfer.
