Troubleshooting IMAP and Compuserve 2000 Problems
1. Does your mail program support IMAP? Not all of them do.
Outlook Express - Yes
Outlook 97 - No
Outlook 98 and Outlook 2000 - Only if you have installed Outlook with the Internet Mail
Only option. To determine your installation type, on the Help Menu, click About Microsoft
Outlook. In About Microsoft Outlook, you should see "Internet Mail Only" if you
have the Internet Mail Only option installed.

Netscape Messenger - Yes
Eudora - Only the latest version, 4.3. Connect to http://www.eudora.com
to download the program.
2. Setting up your mail program to access your Compuserve 2000 mailbox using IMAP.
There are several help files available in the Email & Communications Forum file libraries.
General Information:
IMAPFAQ.TXT
Outlook Express:
OE5IMAP.EXE
OLXIMAP.EXE
Netscape:
N45XIMAP.EXE
N40XIMAP.EXE
Since Compuserve only 'officially' supports Outlook Express and Netscape as IMAP mail programs for use with Compuserve 2000 there are no other sets of instructions.
However for information on using Outlook 98 with an IMAP
server connect to:
http://support.microsoft.com/support/kb/articles/q185/8/20.asp
For information on using Outlook 2000 with an IMAP server connect to:

3. What can go wrong?
If you see an error message when you try to access your email then you will need to identify the source of the error and correct it.
The number one source of errors is a typing mistake when setting up the program. Before you do anything else go back and double check all the settings for the incoming and outgoing mail servers, your email address, account name and password. This will solve the problem in 99% of cases.
Here are some examples:

The incoming mail server was mistyped.

The outgoing mail server was mistyped.

The box next to 'My Server Requires Authentication' was not checked

Either the Account Name or the Password (or both) were incorrectly entered.

If you see this error when sending email

then you need to use the Tools menu in Outlook, Accounts, Properties, IMAP and uncheck the option next to 'Store special folders on IMAP server.'

Then click on the Apply button.
Then click on the OK button.
If you see an error message.

You need to uncheck the option to 'check for new messages
in all folders' in the account properties.
Then click on the Apply button.
Then click on the OK button.

If you have problems deleting messages in your IMAP account folders, remember that it is a two stage process. This is because the folders are not actually on your computer, but on the Compuserve mail server.
So first of all you need to hi-lite the message and click on Delete (this puts a line through the message)

Then you need to use the Edit menu and the Purge Deleted Messages option. This removes the message permanently.

Miscellaneous error messages.
1. If you see the following error messages:
Your 'Inbox' folder was not polled for its unread count.
Account: 'imap.cs.com', Server: 'imap.cs.com', Protocol: IMAP, Server Response: '', Port:
143, Secure(SSL): No, Error Number: 0x80004005
Your 'Sent Items' folder was not polled for its unread count. Account: 'imap.cs.com',
Server: 'imap.cs.com', Protocol: IMAP, Server Response: '', Port: 143, Secure(SSL): No,
Error Number: 0x80004005
Header download for the 'Inbox' folder did not complete. Account: 'imap.cs.com', Server:
'imap.cs.com', Protocol: IMAP, Server Response: '', Port: 143, Secure(SSL): No, Error
Number: 0x80004005
Try this, under Tools | Options | General, remove the check mark from "Send and receive messages at startup". Also try unchecking the option "Always connect ..." inside Tools | Accounts | (select your email account) | Properties | Connection.
2. If you see an error with the code number: 0x80004005 and you use OE 5.0-5.5 uncheck the Accounts|Connection tab box to "specify a connection."3. If you see an error message like this:
The message could not be sent because the server rejected the sender's e-mail address...Please try again later', Port: 25, Secure(SSL): No, Server Error: 451, Error Number: 0x800CCC78
This is a temporary problem with the outgoing (smtp) mail server authenticating your email address. There is nothing you can do to fix it except to try again later.
