Troubleshooting mailbox migration

After the mailbox migration is complete, if some of your organization’s users encounter any issues such as the
Azure
 Active Directory Authentication Libraries (ADAL) form not displaying, you can try to enforce app configuration. In the app configuration for
BlackBerry Work
, on the Basic Configuration tab, select the Enforce App Configuration option. This option ensures that Modern Authentication, EAS/EWS endpoints, and the
Microsoft Office 365
 settings configured in the app configuration profile are applied.
BlackBerry
 recommends that you copy your organization’s app configuration, select the
Enforce App Configuration
 option, and apply the app configuration only to the affected users.
