There are situations that you would like to call back a message which has been sent. For instance, when you find a typing mistake in a message just after you have sent it out, you may not want the recipient(s) read it or you may want to make a correction. In that case, the recall/replace function in Outlook could help. However, please note that you can recall/replace a message only if the recipient(s) are EdUHK staff and the message has not been read. To recall/replace a message, follow the steps:

Procedures:

1. Go to Sent Items.
2. Open the message you want to recall or replace.
3. From the ribbon bar, under the "Message" session, click the Actions menu and choose Recall This Message....
   
4. To recall the message, click Delete unread copies of this message. To replace the message with another, click Delete unread copies and replace with a new message, click OK, and then type a new message.
5. To be notified about the success of the recall or replacement for each recipient, select the Tell me if recall succeeds or fails for each recipient check box.

Note: To replace a message, you must send a new one. If you do not send the new item, the original message is still recalled.
