outlook 365 desktop only syncing all inbox emails from old bellsouth.net account now on yahoo/att
Our business switched to outlook 365.
I have an old bellsouth.net account accessed through yahoo/att.
I set up on outlook 365.
A total of 85000 emails on yahoo/att/bellsouth.net account.
Only 10,000 synced.
I can send/receive current emails fine.
how do i get the 75000 to sync?
I have plenty of memory left.
