I'm currently testing how feasable it is going to be to enable our LAN PC's (currently XP SP1) to run SP2 with the Windows Firewall Enabled for increased security. I've begun testing the setup and everything seems to work and with the exception of Outlook. When I say it doesn't work it displays a kind of quirk. I've noticed no new mail is delivered until I click in a different folder in outlook folder list. Then lots of emails appear in the inbox with different sent times. Same happens if I send a mail. I click the send button and the email sits in the outbox. Soon as I click a different outlook folder the message gets sent.
Any ideas why this would be?
