Note the UID FETCH 119071:* command. Outlook thinks the latest UID it
has seen is 1190710, so it tries to fetch new messages with that

"*" matches the latest existing message (by IMAP spec), the last message
is returned sort-of unintentionally.
I think your Outlook has just broken its internal cache. Try recreating
the account or clearing the cache if you can figure out how.
Maybe that high UIDs did exist at some point and then UIDVALIDITY
changed, but Outlook didn't understand that
Thanks Timo and all; that appears to have resolved the problem in
Outlook. I have had a full day without email incident.
Kind regards,
