I have 4 computers with 4 email addresses all with the same ISP   I would like copies of my sent emails to be cc'd to all computers but windows live mail WONT let me do this. is there a way of doing it.
So, you have the 4 email accounts set up in all 4 computers as POP/POP3 accounts. Am I correct?  If so, are the email accounts in all computers set to "leave a copy (of the message) on the server"?  I suspect not; I suspect the setting in them is to delete the message from the server.  We need to know the settings in your email clients to advise further

If all the email CLIENT in all computers is set to delete the message from the server, meaning delete it after it has been downloaded to *a* computer,  then a CC of an outgoing message should be received by one of the computers.  SINCE a retrieval by any of the computers would cause the message to be deleted from the server, then the message is no longer on the server to be retrieved by any other computer.  You see what's happening here?

If WLM is, indeed, not allowing you to put any of your own email addresses in the CC: box, I suspect that is because it is an illogical situation, especially for POP accounts.  Exactly what happens when you try to put one of your own email addresses in the CC: box? 

Another type of email account, an IMAP account, is what you should have to accomplish what you want to do.  IMAP is designed to synchronize email accounts among multiple computers.  However, some, or perhaps many, ISPs do not support IMAP.  If this is the case, a non-ISP account, i.e. from an email service that offers IMAP accounts, can be the solution.

Do you want to use all 4 computers to both send and receive, or do you normally use one computer to send and you merely want the messages on the computers for viewing purposes? 

Another option, in addition to the IMAP mentioned above, is to access your email accounts via web browser.  This way, the same email folders and messages would appear on screen regardless of what computer was used, including computers besides the ones you own as long as login by username/email ADDRESS and password are entered.
I have them set at various retentions. up to 50 days  (from 5 to 50 days)


when I send an email  I often have information in the sent email that I want to refer to  but often I am MILES away so if I could cc to myself I could retrieve the emails and store them indefinitely.

each computer downloads the same sets of emails.  so sending a cc to myself solves the problem.

but windows live mail says I am sending it to one of my own email addresses so brings up an error.

You don't have to use live mail.
If you have an account with another provider, you can send with that and do cc to you live.com account.
This article has some issues, but gives you an idea of what is out there.

Look for a good provider that lets you leave mail on the server until you delete it.


BTW: I send e-mail l to myself, but never answer. Quote from: Geek-9pm on February 08, 2014, 10:35:21 PM
