Hybrid migration to Office 365, mailbox rights such as Full Mailbox Access, Send As and Send on Behalf are not getting migrated -
Descripción
Hybrid migration has been set up. Source users are located in on-premises Active Directory and source mailboxes are in on-premises Exchange, users migrate to target Active Directory forest and mailboxes migrate to Office 365 using Quest Migration Manager. Microsoft Azure Active Directory Connect is set up to synchronize users from target on-premises AD to Office 365. Everything is working as expected, however mailbox rights such as Full Mailbox Access, Send As and Send on Behalf are not getting migrated.
Is there a way to migrate these rights?

Causa
As per Migration Manager documentation, it is strongly recommended to use only the Empty Active Directory to Microsoft Office 365 mapping template during migrating objects and synchronizing directories. If you need to process specific permissions such as Send on behalf, add the corresponding mapping rules to the template.
