First, email usually works the first time, and quickly, but if you do get a message bounced back to you, try sending it again. (Otherwise you may spend a lot of time trying to troubleshoot what may be a temporary net work glitch.)

Pay attention to the ENTIRE error message! It will often tell you precisely why your message failed and give you a good idea of how to fix it.

Common Outlook Errors
Program keeps asking for Username and Password
Occasionally, Outlook has been known to 'forget' the username and password that you set in the program. When it does this, it usually presents you with a username and password window that seems to already be filled in with the right information. In this case, it is a good idea to remove both the username and password from that field, and re-enter it.

Common Email Errors
"Undeliverable mail" (no other errors listed)
This is usually caused by an incorrect user or host name. Check the address and if possible verify it with the person you are sending it to.

"Bad host name." or "The following address had permanent fatal errors."
This can happen for two reasons. Usually this error means the email address was mistyped. Check the address and if possible verify it with the person you are sending it to. Or, this error can mean that your system does not recognize the host name. Ping the domain name in the email address. If it doesn't connect, or recognize the hostname contact your Mail Administrator (Computer Person), or Oasis Technical Support.

"Local configuration error."
This error means that there is a problem with the email account that you are sending to. Check the address and if possible verify it with the person you are sending it to. If there are no obvious errors, ask the recipient's Mail Administrator (Computer Person) to help.

"Looping message detected."
This error gets sent when two or more mail servers disagree about the correct location of the recipients mailbox. Check the address and if possible verify it with the person you are sending it to. Sometimes this problem can only be solved by the local Mail Administrator (Computer Person) for the address you are sending email to.

"System timeout during mail transfer"
This error usually occurs because the recipient's mail server (or a mail server along the way) is either unreachable or overloaded. There also may be a network error. Verify the address with the person you are sending to, their Mail Administrator (Computer Person) may be the best person to troubleshoot this problem.
