At home I have Outlook 2010, if I click a mailto link in a web page the outlook spash screen shows and a new email is created with the correct "to" information. I compose the email and send. All seems fine.
However, if Outlook is not actually open then this email will sit in the outbox until Outlook is opened at which time it will then send.
Is this by design? Have I missed a setting/option. I've never know this behaviour in previous versions of Outlook. From memory (I'm not at home to check) I have the send mail straight away option enabled and it uses my LAN (not wait till I connect)
Only thing I can think of that *might* be an issue is my iPhone connecting to my ISP at a similar time and so Outlook not connecting.
I have observed this behaviour doing a send/receive in Outlook after my phone has just done a "pull" email from my ISP. But this has usually been a receive problem connecting to the mailbox and not a send issue
