Read migrated mail marked s unread

Hi,

configured ODME for a migration from Exchange (hosted by a provider) to Exchange Online.

We are in the phase of testing with some mailboxes and noticed that after synced mail data all read e-mails from

source mailbox are marked as unread after the syncing process is completed. No evidence of a configuration setting to avoid

this problem.

Could you please help to diagnose?

Thanks.
