Q: since end of Sept 2013, the mail client on my WindowsMobile 6.5 device refuses to send icloud mail.  Receiving works, sending produces the error message "check your internet connection and your account information".  Any way to fix this problem?

remaining free space on icloud is 3.6 Gb; deleted and re-established the mail account on the device several times, following instructions from Apple KB doc <http://support.apple.com/kb/HT4864> without success.  Unfortunately, the mobile device (HTC HD2) can't be updated with a newer windows version, Android is no alternative, either.  Can anybody help???

Cheers,   Andreas
