Problem with Mail (Lion)

I had a problem with Mail on my 2010 MBP 15" always promting for my password. I would check save to keychain but it would never save and continued to prompt. I tried the various suggestions others in the discussion have offered with not no luck. I suspected the issue had to be with Keychain. I noticed that the login.keychain file in ~Library/Keychains had some messed up permissions. (To access the Library folder select Go from the Finder menu bar, press the alt/option key and then select Library.)

It two entries for Everybody; on set to custom and one set to No Access. It also had another user set with Read & Write prermissions, staff with Read only and me as Read & Write. I

I removed the everyone user with custom permissions and removed the other user leaving Me with Read & Write, staff with Read only & everyone with No Access. After this change mail works with no further issue.

I hope this helps others.

Ok, maybe this is good but the idea of just pasting in someone’s terminal commands deserves some caution and consideration.

And…speaking ‘scientifically,’ — you might start by specifically identifying what problems this is intended to resolve rather than “a problem like me and many many others guys,”

Make sure that at least "Basic Authentication" is enabled in IIS on the EWS folder of the Exchange server. (Exchange 2007 / 2010)

That did the trick for me.

For some reason Apple decided to change the default authentication type in Mail to NTLM following the upgrade to Lion.

This works great for authenticating against an Exchange server or an Active Directory domain, it does not work so well for non-Microsoft solutions.

If you're having problems with "MAIL", check you account preferences in Mail for the authentication type, it should be in Preferences, Accounts, Advanced; then change the authentication option from NTLM to Password.

Shyannlindy's solution worked for me!!!

Apple Mail was working completely with my MacBook, but when I tried to use the same email on a used MacBook Pro that I just bought, i could get incoming mail but not outgoing mail. I even tried the email account on Outlook on my MBP and same problem: The outgoing server couldn't be connected (but my incoming was fine).

Since I knew it wasn't the account information (since that same information was working on my MacBook), I knew it wasn't my email server (because the other mac and email used the same server info) I knew it had something to do with my MacBookPro settings. Both computers run on Lion

I followed Shyannlindy's advice and that fixed my problem!

I've had this issue as well several times over the last few OS's and Apple Care has always recommended ShyandLindy's solution. And it does seem to work for a while. But it always seems to come back at some point!

The problem with this solution is that you have to re-import any mailboxes you've created, from the mail folder you've dragged out to your desktop. I've always liked to save emails in a long list of mailboxes with sub-mailboxes in each. When I do this fix and re-import my mailbox list, it creates all these duplicate sub-folders, one with a title that has a bunch of numbers, and the other called 'messages'. In these are just duplicates of the emails that are sitting in the folder that contains these sub-folders. Soooo, I have to go in and delete all these newly created reduntant folders, to try and re-organize my mailboxes which takes an hour or two!

I've realized that its not worthwhile trying to save emails this way (maybe theres a better way to store your emails?).

This is getting very frustrating.

I'm experiencing the problem for one week now. It suddenly was there. Out of the blue, not after any change or update. After 8 months without problems with Lion and this machine. The ShyandLindy's solution works partly.

It's a shame.

Maybe, maybe there's a relation with the Preview application. I used the option File --> Mail before the problem occurred. To mail a pdf document directly from the Preview application.
