One of the workstations in the office is having difficulty with Outlook. The automatic send and receive is not working. It did work, but then stopped working. If you press send and receive or exit Outlook it sends and receives email. I have checked all the settings and they look fine. The windows firewall is off. Outlook is not running offline. I have installed all upgrades from Microsoft. This is the Microsoft Office with Business option. I also removed the pop3 email account and added it back.
