While migrating from one Active Directory environment to another using Quest ODM AD Dirsync, SID History did migrate for some users but not for others.
The impacted users could be mailbox enabled in the target AD environment and do not have "Allow Mailbox Updates" checked/enabled on the migration template.
Check/enable "Allow Mailbox Updates" on the migration template.
It's possible that in template, Mappings other mailbox-related attributes may need to be removed because syncing them from the source may affect the mailflow and target hybrid users. Please consult Quest Professional Services for details.
