OL2002: Sent Messages Remain in Your Outbox
The information in this article applies to:
Microsoft Outlook 2002
SYMPTOMS
In Outlook 2002, sent items may remain in your Outbox folder. Because the items do not leave the Outbox, you do not receive responses to messages, meeting requests, or task requests. In this situation, you do not receive a warning that the items have not left your Outbox until you quit Outlook. When you quit Outlook, you may receive the following message:
There are still e-mail messages in your Outbox. Would you like to exit anyway
Exiting in seconds
CAUSE
This behavior occurs if you are working offline and one of the following situations is true:
You addressed the item to someone in your local Personal Address Book (PAB).
-or-
You use a Microsoft Exchange Service and addressed the item to someone in your synchronized Global Address List or your synchronized Outlook Address Book Contacts.
MORE INFORMATION
If you are working offline, Outlook 2002 cannot send the item because it does not have access to the e-mail server. Because the addressee is available in one of your local address lists, Outlook validates the address. However, Outlook does not provide an indication that the item remains unsent until you quit Outlook.
Outlook sends the messages the next time that you make a connection to your e-mail server by either working online or making a remote e-mail connection.
To make a remote e-mail connection while you are working offline, click Send/Receive on the Tools menu, click Work With Headers, and then click Download Headers.
