Outlook 2007 was working until a couple days ago. Now it will not send emails. Actually it looks like they are sent because they end up in the sent items folder. They are not stuck in the outbox. I can go to the account setup and press the test and both the incoming and outgoing tests pass. Still it wil not send emails to my contacts. If I use the web client for my email provider - emails are sent so it it not the email provider.
Ran Microsoft Office Diagnostics - no problems found. Deleted and recreated the account in Outlook - emails still won't go to person it was sent to but shows in sent items.
