257824 OL2000: Differences Between Outlook and Outlook Express



SYMPTOMS
When sending e-mail with an attachment from Microsoft Outlook 98, you may be disconnected from your Internet Service Provider (ISP).



CAUSE
Your message and attachment may exceed the allowable message size on the ISP server.



RESOLUTION
Contact your ISP to see if another server is available which will handle your message and attachment.



MORE INFORMATION
Some ISPs provide two Simple Mail Transfer Protocol (SMTP) Addresses, one for most messages and a secondary one for handling larger attachments. Many ISPs will automatically switch between these servers based on need. If yours does not switch automatically or will not allow you to connect to the secondary server by default, you may need to split your large attachment into smaller ones.
