Hi,

I use javamail to read message in a public folder on a MS Exchange
server. (It's simple: instead of "Inbox" you give it "Public Folders/My
Folder".)

However, accessing some messages fails. Trying to get the subject or
the sent date, etc throws an exception with a message something like (I
apologize me for not remembering exactly, I can only get this on my
intranet - which I am not right now):

Unable to open MAPI envelope.

Can you suggest what might be causing this problem? Out of every 100
emails this happens to about 5 emails. When I inspect those emails via
Outlook, I don't see anything special about them.

Thank you so much in advance

Aaron Fude
