Horde error "Login Failed" while user & password is correct

One of the e-mail accounts in my server frequently performs "Login Failed" when logging in to horde webmail while the username and password is right.

It happens once within 1-2 day that the username & password cannot be used to login to horde webmail,
there's error "Login Failed" while the username & password is absolutely right.

I've treid the command "\mchk.exe" --domain --domain-name=domain.tld, it doesn't help.
What I have to do is removing the mailbox, and recreate it again. Then it will be able to login.
I have to backup all messages in the inbox, and recreate it again and again every 1-2 days for many times.

Any suggestion? Please help. Is there anyway to fix it permanently?
