In dynamics 365, what table are notifications stored before being emailed

Hi,

I restored my CRM from a backup through deployment manager.

I would like to know in what table are notifications stored before being emailed through the exchange server?
I have also set the date to the current date in the Exchange synchronization for the field "Process Mail From"

Currently if I enable to process notifications it is sending old email notifications.

Any help will be greatly appreciated

Thank you
