dovecot -n output could be helpful. Also did you look at logs? Maybe

I didn't want to send it, because I don't know, which part is useful in
this case.
there are errors. http://wiki.dovecot.org/Logging
Actually I've juest enabled all debugging related options, except
password. I'm afraid, there will be too much messages.
Anyway, the possible reasons:
1) Dovecot changed the UIDLs because something weird happened. In that
case it logged an error.
No error.
2) Did you use the courier migration script so that the UIDLs got
converted to Dovecot? If not, maybe Outlook got confused because the
UIDLs changed, and fixing it would require recreating the Outlook
account or something..
No, there was no conversation.
I was thinking about recreating the account, but it's not possible right
now. It will be actual in 1-2 weeks.
Anyway, even if it help, there is an error, which does not happen all
the time, still I think it's server related.
3) Outlook just doesn't like the new UIDLs and messes up itself. I think
Courier usually uses maildir filenames as UIDLs, you could have kept
doing that with pop3_uidl_format=%f. But changing it now would cause
users to redownload everything again.. With v1.2.5+ you could use
pop3_save_uidl=yes to make it possible to change UIDLs on the fly.
Are you sure, it can be enabled on the fly and if I use it, the mail
won't be donwload again after changing the uidl format?
Thank you,
