The symptoms: when the Mail application is "closed" on the iPhone, Outlook

That's strange. Normally an IMAP process shouldn't be holding any locks
at all. Can you check if there are any *.lock files that get deleted
when killing the imap process?
that's why I asked you whether there is a way to tell Dovecot only
one POP3 or IMAP process from the same user, the latest one, can be active
at the same time, closing and disconnecting all the others.
No.
pop3_lock_session(pop3): yes
This means that during the whole POP3 session Dovecot locks the mailbox
by creating dovecot-uidlist.lock. If it can't, it gives the "mailbox is
in use" error. So I could understand if there was a long-running pop3
process holding the lock, but imap processes really shouldn't be doing
that..
In fact - that's what puzzled me.
To have a simpler test case, this afternoon I upgraded Dovecot to the
latest release leaving only the mbox storage (we are planning to convert
to maildir in September) and, even if I don't think there is any relation
with our issue, set that server MTA (Exim 4.69) to use both fcntl and dot
lock files.
The user who got the bizarre situation should be back in a few days;
should the problem be still there, I'll sure tell you all.
Thanks a lot again; regards
