Hi all,

Upgraded to High Sierra last night. I have two mailboxes that run off the Exchange protocol that are no longer responding post-update. Outlook and another Exchange inbox are working fine...

Any idea what's causing this and how to address? These two inboxes are rather important so I can't go without.. thinking of downgrading back to 10.12 (though I'm not sure how to do this. Simply restore from Time Machine?
