Mail Messages Suddenly Blank!

I've had a similar problem in finding my "Sent Mail" folder appearing empty.

It occurred to me recently that the operating system (for some reason) may have changed the "Read" permissions on the files or folders within Mail.

I ran "Disk Utility" and had it "Repair Permissions" on my Mac's hard drive (i.e., "Macintosh HD") and this seemed to fix the problem.

You might want to try this solution.

Since upgrading my wife's iMac to Mavericks, all of her e-mails are blank; they will show as many lines as one wishes in "preview" mode; but if one goes to classic mode, or if one clicks on the e-mail to read it fully or to reply, they are blank. I've reindexed; used Hazem Malek's technique; cleaned up permissions; all to no avail. Exported mboxes and reimported; the problem is very persistent and very irritating. I'm a long-time (1990) Apple user, and this is the worst experience with Apple yet, in nearly 25 years. If someone finds the silver bullet, please pass it along.

If Mail detects problems with information in your mailboxes, it may need to repair the mailboxes by reindexing your messages.

At other times, you may want to reindex messages yourself—for example, when searching mailboxes using Subject, To, or From doesn’t return the correct results.

1. Quit Mail if it’s open.
2. In ~/Library/Mail/V2/MailData, delete any file that begins with “Envelope Index,” such as Envelope Index or Envelope Index-shm.To show your home Library folder, hold down the Option key, then in the Finder choose Go > Library.
3. Open Mail.Mail creates new Envelope Index files. This process may take a few minutes, depending on how many messages Mail is reindexing.

I tried most if not all of above approaches; none worked. But this did: I made a careful note of my Mail account details, then deleted that account and created a new one, with the same details. All now working fine!

A SIMPLE SOLUTION

Go to the Preferences.

Select Viewing

Select the Classic view tick box

You can now see the message content. Why this works is beyond me but it works. if yu go back and untick the classic view the blank messages disappear but it seems that no more blank messages occur.

Weird. Same thing happened to me but before going crazy, (all these things drive me nutso) I restarted the apple and that seems to have fixed so far. Sometimes too, it helps to delete the email from mail then add it again. I also did the simple solution above which did not work for me. I was ready to go off and do bunches of fixes but try restarting the entire mac first before doing all the fixes. Apples often have the habit of fixing quirks on restart. Anyway thanks for all the good information.

I have fixed my iPad mail app that went blank and it also appeared frozen ...you have to make sure that you have not used up all your iPads memory by adding to many apps. If you have over loaded your apps just eliminate/delete the apps you're not using. Presto it fixes the problem

I had the same problem: empty Apple mail folders alter changing the email pop settings.

13000 emails gone in a second...

Spotlight still found them.

Deleted the envelope index files (3), and everything was back again.

THANKS!!

I rarely bother with all this 'safe booting' 'rebuilding indexes' 'repairing permissions' because 90% of the time it is a waste of your time.

I get this Mail.app problem intermittently as well. I like Mail.app because it's nice to have everything in one place. I also archive everything and back up. Anyway, quitting and restarting Mail.app doesn't usually do the trick but restarting once or twice does.

Wow! This solution worked for me! From approx. 750 Mails more than a half were blank/empty and even not listed, when I put some phrases in the search field. With your solution everything is working again, no more empty mails and every searched mail shows up in the search field. Thank you very much for this solution!
