just noticed my Outlook 2010 on Win XP SP3 doesn't want to send message. For example, I created message and clicked "Send" button. The message goes to "Outbox" folder and wait me to initiate "Send/Receive" command. If I do "Send/Receive" then message sent with no problem. But if I decided to open it for editing (or just click on Outbox folder without opening a message inside it) then this message never send - it just seats in "Outbox" and Outlook doesn't provide any errors when sending/receiving messages, it seems Outlook doesn't see anything in Outbox! So I have create a new message and send it immediately to have a success. Sometimes it is bothering... Any idea is appreciated.
