I have a pop3 email account set up in Apple Mail and now that I have upgraded to Snow Leopard, I would like to make it an Exchange account. How do I change that account to use Exchange, making sure all the mail in that account isn't lost?

I'd try the following:

  1. Back up your email -- make a copy of ~/Library/Mail
  2. Create a new account in Mail to connect to the Exchange server. Mail will take its time and sync email with what's stored on the server.
  3. If there's any mail you store locally (under the POP3) account that you now want stored on the Exchange server, drag it to a folder on the new account. This will update both the local and server-side copies of the email.

If your POP3 account was configured to download all email and store in local directories, you can leave the email where it is and not copy it to the server. You'll still be able to access it. Just turn off the POP3 account's automatic pulling of new email.

Personally, I prefer to have Exchange be the primary store of my email -- IF you trust the server administrators with proper maintenance and backups.

I am assuming you have an exchange server up and running?

There is no way to directly convert. The best way is to create your new Exchange Account and log in using Entourage or Apple Mail. Manually move all your mail from the POP3 account to the new Exchange account and then remove the POP3 account.

Once done change the DNS entries to point to the Exchange machine to recieve mail and remove the POP3 account completely.

I do have the exchange server up and running. The POP3 account is actually pointing at the exchange server, but just pulling mail through POP3. How do I "manually move" all my mail from the POP3 to the Exchange account? Do I do that on the server or on my local machine? – Austin Aug 31 '09 at 14:20
