大家都知道，當我們使用outlook express的IMAP方式收發郵件時，發出的郵件都會轉移到郵件服務器的寄件備份資料夾里。這樣，當我們用任何一台電腦、使用IMAP方式時都可以看到我們的寄件備份。

奇怪的是，當我在OUTLOOK 2003里也采用了IMAP的方式，發出的郵件卻只能保存在本機的寄件備份資料夾里。不能被移到服務器的寄件備份資料夾，當我們換了一台電腦或出差在外時，就不能看到我的寄件備份了。

郵件服務器環境：linux+sendmail。

OE是沒問題的。
OL為什么會這樣子呀？

发出去的在OE也不行吧。

OE是沒有問題的。
就是OL不行。

我試過outlook 2003中文版，outlook 2003 英文版，都是不行的。
OE里套用IMAP方式時，有一個選框：“將特殊的資料夾儲存到IMAP伺服務器”，而OL里就根本沒有這個選框。

STORING SENT ITEMS ON AN IMAP SERVER

As anyone who has ever used Outlook with an IMAP account knows, Outlook doesn't handle IMAP accounts well. The most irritating issue for most people is how it saves sent messages in the local message store instead of in the Sent folder on the IMAP server. You can use Rules to copy the sent message to the IMAP Sent folder, but you'll still have a copy of the item in the local folder unless you turn off the option to Save copies of messages in Sent Items folder. Keep in mind that if Outlook is unable to connect to the IMAP server for whatever reason, a copy of the sent message isn't saved at all. If you have two or more email accounts and disable saving sent items, you'll need to create rules for each of the accounts if you want to save the messages sent on each account.

To set up the rule:

Go to Tools, Rules and Alerts (or Rules Wizard)
Create a new blank rule
Select Check messages after sending
Select a condition if you want to only copy certain items to the IMAP folder or leave it blank to copy every item you send. Click Next.
Choose Move a copy the selected folder as the action and select the Sent folder on your IMAP server. Click Next.
Set up any exceptions and click Finish.
Now all messages (or those meeting the conditions you selected) you send are copied to the IMAP server.

If you don't want a copy of the sent messages stored locally, open Tools, Options, Preferences, Email Options and remove the check from Save copies of messages in Sent Items folder. If you have more than one account, you can create a rule for each account.

A KB article details this method using the condition of 'messages using the Message form' so that it applies only to messages, not task or meeting requests. Although it's written for Outlook 98 Internet Mail only mode, it works will all versions of Outlook.
