Synchronizing - "Too many simultaneous connections from"

Outlook 2002, SP3

One of my email accounts keeps giving me this error message:

Task 'Mail_account - Sending and Receiving' reported error (0x800CCC90) : 'Your incoming (POP3) e-mail server has reported an internal error. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).  The server responded: ??RR Too many simultaneous connections from'

Sometimes messages don't download upon synchronization but eventually they do. The address, "", translates to "". My ISP and DSL provider is Earthlink. I have an onoing conversation with their tech support but it doesn't seem to be leading me anywhere.

An interesting fact is that one of the three computers on our home network does not exhibit this behavior. The two do.

Any ideas?

    Many thanks for your response. Just this morning, I managed to solve the problem. On further research into the exact error code Outlook was giving me, I found an article that was relevant to the problem I was having. As I had suspected but my ISP couldn't/wouldn't acknowledge, the root cause of the problem was that the ISP limits the number of POP3 connections that one can make at the same time. The reason I kept getting the error message, "Too many simultaneous connections from" was because I was checking 6 mail accounts in my one Send/Receive group.

    Here's how I solved the problem. I created a second Send/Receive group and activated checking for half the accounts. Then I removed those accounts from the existing Send/Receive. Now, when Outlook performs a Send/Receive, I see no errors.
