Win2003的microsoft outlook 用exchange 顺利，但POP3/SMTP邮件服务器对外部邮件地址能收不能发
I tried all suggestions, but it didn't work for me. What I found was that Outlook still had some Exchange addresses in ' it's memory' and the message to be sent included an exchange address, whereas exchange was not being used anymore.
export my personal folders to a backup.pst. Then rename that backup.pst to outlook.pst. NO HELP.
This could happen on systems which have used Exchange but have changed back to POP3 E-mail delivery.
Checking the to-be-sent messages is the key, remove the addresses that are exchange addresses and substitute them with the real POP E-mail addresses.
