emails sent with "send object" macro sometimes get stuck in Outlook outbox

I have an Access 2007 macro that uses the send object command to send emails with an HTML attachment. My problem is that around 20% of th开发者_运维百科ese emails get stuck in the Outlook outbox. For some unknown reason, the "delay delivery" checkbox in Outlook is automaticaly checked off to delay the delivery, for these emails. I dont know if this is relevant, but I use the app "Click Yes", in order to automatically authorize Outlook to send the messages. Please advise what I can do in order not to expereince the emails from getting stuck in the Outbox THank you very much, Nathaniel

SendObject is not very versatile. To control these things you likely have to automate Outlook, which has its own set of complications. See Tony Toews's Email FAQ.
