Hi,
I encountered this problem recently.
I discovered that you cant have more then 3 levels of sub folders.
For instance, there is
INBOX, DRAFTS, SENT ITEMS, TRASH, OTHERS. - root level
then within OTHERS, there are is a folder call A.
with folder A, there is A1.
However, when you reset the IMAP folder list, Folder A1 is gone. So does all the mails. I think this is a very serious problem. I am using IMAP and Outlook Express as the client. Have anyone encountered this before?
I later discovered that by creating a folder A1 back, the mails will all of a sudden appear again. I think this is a pretty serious problem. I am not very good in this area, but I hope perhpas someone already have taken notice of this.
Thanks.
