Test sending an e-mail message (to yourself) through Outlook. This test will ensure you can send and receive e-mail on the Link2Exchange server and will make sure you're not over your account quota.
Click File->New->Mail Message.
Type your e-mail address in the To: box.
Type 'testing email' in the box next to Subject.
Type 'Testing Outlook email' in the message box at the bottom of the new message window.
Click Send. Because you're using Cached Mode Exchange, the message may take 5-10 seconds to be delivered. If it takes any longer than that, click Tools->Send/Receive->Send/Receive All
If you received the e-mail message then your Outlook mail profile is configured correctly and is connected to Link2Exchange.
Test receiving e-mail from a non-Link2Exchange account.
Log into your non-Link2Exchange e-mail account and send your Link2Exchange account a message. The purpose of this test is to ensure that the rest of the Internet can send e-mail to your Link2Exchange account.
