Hi,
I have exactly the same problem, we use exchange 2010 too (pop or imap) :
DEBUG: setDebug: JavaMail version 1.4.5
DEBUG: getProvider() returning javax.mail.Provider[STORE,imap,com.sun.mail.imap.IMAPStore,Sun Microsystems, Inc]
DEBUG: mail.imap.partialfetch: false
DEBUG: mail.imap.statuscachetimeout: 1000
DEBUG: mail.imap.appendbuffersize: -1
DEBUG: mail.imap.minidletime: 10
DEBUG: trying to connect to host "192.168.0.202", port 143, isSSL false
We have no firewall between AlertCenter and Exchange Server.
When we tried to download log file we have exactly the same error : "file cannot be downloaded" (error 404).
Have you an idea ?
BR,
Antoine
