Migrating a BlackBerry Work mailbox from an on-premises Microsoft Exchange Server to Microsoft Office 365

You can migrate a BlackBerry Work mailbox from an on-premises Microsoft Exchange Server to Microsoft Office 365 with minimal user interaction. Before you start the migration, BlackBerry recommends that you select the “Migration Flow Enabled” option on the Advanced Configuration tab of your organization’s app configuration for BlackBerry Work. The benefit of updating the app configuration before you perform the backend migration of the user’s mailbox is that the user’s email will continue to be synchronized and the app will not switch to offline mode during the migration. The user might be required to enter their credentials during or after the migration. This feature requires BlackBerry Work 3.2 or later.
