Power365 fails to Prepare users, getting stuck at 75%preparing within Directory Sync when trying to match and prepare for email migrations. We have verified the users exist in Azure AD.
This is a Hybrid to Hybrid Environment
Both the source and target are in Office 365 and their AD objects are synced from AD On-Premises. Neither environment has a Exchange Hybrid server. This is a migration from one O365 tenant to another O365 tenant where both are managed from AD On-Premises. We are syncing users and groups using Power365 Directory Sync.
