i have no Outlook 2016 to test but if you setup is right
no trouble should come up, however simply look in the dovecot log files
what your user did, perhaps he was offline and only thinking that he
synced via imap

I've observed similar behavior for a user with Outlook 2013 and Panda 
IMAP;  when synchronization failed for whatever reason, Outlook wasn't 
very verbose about it, and the user continued operating for several 
months not realizing their local mailbox had entirely diverged from the 
"true" contents on the IMAP server.

never had this with Outlook 2013
but ost files may brake any time , also with exchange
mostly with big mailboxes, and there is less you can do against buggy
users, give them webmail to show real imap status on the server
