Mail.app not working after migrating from Early 2008 MacBook Pro (Mavericks) to MacBook Pro Retina Display Late 2013

Thank you!

This worked for me too!
I migraed over from my Macbook Pro 15" to a Macbook Air , it all went wel but was unable to use my email accounts in mail.

Everytime id add an account nothing would happen but I can confirm this worked for me! Thank you Sir!

Thanks fir the detailed instructions. Worked instantly.

This completely resolved my problem. Thank you.

Another thanks to Adamalicious -- I have been trying to solve this problem on my new mac mini after migrating from my macBook Pro.

Done. thanks.

Many thanks, Adamalicious - once I worked out how to unhide my Library, this fix worked instantly. With gratitude, MC.

Thanks this has aslo work for thanks for the info! 🙂

Thanks so much everybody and Derrick_C for explaining how to solve this issue and how to access hidden files.

I spent hours trying to fix mail after having migrated to a new MacBook Pro Retina.

Deleting the file Container.plist totally solved my issue.

Thanks, Chris.

I could not find the different things in the library so what I did was:

1. Went into applications

2. Right clicked on email app

3. Clicked on duplicate

4. Drug it down to my dock

5. Went to my "non-working" email app

6. Right clicked on the non-working email app

7. clicked on options

8. clicked on "show in finder"

9. It disappeared into finder and I opened my copy of email, IT WORKED! YAYY!

This workd for me when migrating from my MacBook time mashine backup to a clean installation of Maverick on an iMac. I had the same problem as stated in the first post and after deleting Container.plist but I had to delete also OldData folder which is located in the same folder. After 3 weeks of searching for a solution for this problem it finally worked. Thanks ! 🙂

This solution worked for me, as well. My thanks.

Thank you Derrick_C this worked for me too! Saved me a lot of time and frustration!

I tried moving, deleting, configuring and tweaking all kinds of things last night to fix this. Finally i used the right google search this morning and ended up here. Thank you @Adamalicious for the original solution and @abence82 for the clarifications.

Hi everyone, I'm facing the same issue just did migration from MBP mid 2010 to a new MBP Late 2013. Could not locate the folder "containers" anywhere checked folders and used finder. Can't be found. folder is nowhere to be found. Any ideas? Thanks !

Container.plist is a file, not a folder. Just follow Derrick C instructions :

(1) In the Finder, choose Go > Go To Folder

(2) In the Go To Folder dialog, type the name of the hidden file, in this case:

~/Library/Containers/com.apple.mail/Container.plist

(3) Click Go. This will take you to the appropriate location to see the file and move it to trash.

Gilles, thank you. I meant file, but I checked all the options presented here including this one. When I do tha on finder/go/folder I get the message The folder can't be found as shown in the pic below. Crazy right? If anyone have an idea let me know please. Will talk to Apple. Very disturbing these issues. Thanks !!!
