[neomutt-users] cannot read maildir, saying no message

[Kiyoung Park]

I have main maildir which is connected to imap server via offlineimapd.
And I have a few maildirs which is converted from Thunderbird mbox.

When I set up neomutt a few month ago, all maildirs worked fine
and I could access all mails.

For a while I haven't opened old converted maildirs,
and today I opened it with neomutt but I could't get any mail.
For all mailboxes in these dir, there is no messages showing up at
neomutt at all.

Certainly, it worked when I first set up a few month ago,
and I assume I haven't changed any setup with this account.

There are still files like "1611909138.000000.mbox:2,S" in path/cur dir.
The file starts with the lines of:
X-Account-Key: account2
X-UIDL: AAg78qFAAAgN2TGHtITlI6kYk4Eyy/FL
X-Mozilla-Status: 0001
X-Mozilla-Status2: 00400000
Received: from ...

Any ideas?

Best,
Kiyoung
