email on one computer (set to until I delete)but not another, doesn't show on server
I have Thunderbird on 2 computers, same email acct. Both set to leave messages on server until I delete. A message was downloaded on one computer but not the other. Performed search but message not found. Logged on to server (AT&T), performed search, nothing found there (very strange). Previously when one computer downloads but not the other, the message is found on the server, as only makes sense. This issue is troubling as it is my business email, and the two computers have different operators, each of whom ignore messages directed toward the other operator. Just chance that one operator asked the other if he had seen a certain message, which he hadn't, as it did not download. Any solutions or explanations would be appreciated. Thanks.

Personally I have two suggestions. Probably not what you want to hear..
1. Get a mail service from a provider that actually has an interest in providing a quality service to something other than a web portal. That is NOT any ISP I have interacted with in recent years. Although I am sure some of the smaller business focused providers still offer such service.
ATT do stand over the past few years for their repeated failures in email and their aborted outsourcing to Yahoo. (most ATT mail account were included in the yahoo hack as they were on yahoo servers at the time). I would not recommend then as a place to store any business critical data.
2. Use IMAP for mail accounts that are to be synchronized between more than one device. POP has never been a good tool to be used as you are. It works, but the basis of POP is download. The basis of imap is synchronization.
I am sure you would be able to see the benefits of an account system that is designed to synchronize over one that was not in this circumstance.
