When you try to receive e-mail messages in Microsoft Entourage for Mac or Microsoft Outlook Express 5.0 for Macintosh, you do not receive e-mail messages. Additionally, you may receive the following error message:
Mail could not be received on account account_name. The domain name servers are not responding
This problem occurs when one of the following conditions is true:
The e-mail server on your Internet Service Provider (ISP) is down, or the server is not operational.
Your e-mail account information is incorrect.
Your Entourage or Outlook Express identity is damaged or corrupted.
Also, this problem may occur if you try to run Microsoft Entourage 2001 for Mac in Mac Classic OS (Mac OS 9) under Mac OS X, and the Internet preference files are damaged.
To resolve this problem, use one of the following methods:
Method 1: Contact your ISP
Your ISP can determine whether your e-mail server is operational and if your e-mail account settings are correct. If your ISP is not operational, your ISP can inform you when your e-mail server will be operational again. Also, your ISP can tell you if your e-mail account settings are correct.
Method 2: Rebuild your Identity
If your ISP confirms that the e-mail server is operational and that your e-mail account settings are correct, your identity file that Entourage or Outlook Express uses may be damaged, and the identity file must either be repaired or replaced with a new identity file.
