Q: since i downloaded mavericks, my email won't work What do I do?

Have you tried restarting your Mac? Will the Mail app launch or does it just refuse to launch?

im having the same problem and ive restarted and checked all my email settings as well still nothing!

For me, mail "works", i.e. it starts, but with the same settings that I had in MacOS 10.6.8, neither imap nor pop accounts can be accessed. Passwords entered in "Internet Accounts" get forgotten.  On my iMac, still on 10.6.8: no problem. I am fed up with Apple Mail under Mavericks.

Keychain Reset

Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

Feedback

Thanks, I did send feedback.

The keychain reset did not help either, so I switched back to my old keychain using terminal (cd ~/Library/Keychains) and renaming the "renamed keychain" back to the original, because I had many items in it.

The problem may be in the "Local Items" folder that I cannot access, because it uses a password that I don't know. I also could not remove this bl... folder.

Another point: Thunderbird does work with exactly the same settings!

I confirm that I have the same issue.

Since I'v got Maverick Mail is running out of time and memory. It takes ages when you start it before you get your mailboxes opened...

Note: All is fine on iphone.
