Mail not showing new messages in inbox

Dear Ronroyer,

Since I haven't upgraded to Mavericks (10.9) yet, I can only be of limited help.

You mention multiple locations, but not multiple computers.Are all of these issues occurring on one computer? The fact that it sometime affects all your email accounts at the same time leads me to believe that there's an issues in your Apple Mail preferences. You can try going into your library and removing "MailAccount.plist." Keep the file on your desktop. Don't delete it.

Note: you may have to use the following info to make your library visible. <http://www.macobserver.com/tmo/article/mavericks-easily-make-user-library-folder -visible>

Here's the path:

YourAccount/library/ApplicationSupport/Mail/OnlineAccountTypes/com.apple.updated .mailaccounts/MailAccounts.plist

After removing the file, restart your computer and launch Apple Mail. It should rebuild the "MailAccounts.plist" file. If not, you still have it on your desktop. Experiment with Mail for a while and see if the problem persists.

Good luck.

Hey Ron - About 3 weeks ago I spent a couple of hours on the phone with Apple Support about this issue because it is also sporadic on my new MBP that came pre-installed with Mavericks i.e 'Get Info' generally does still work but then I can miss mail for several hours before it appears in my inbox. On my iPad and iPhone there are NO such issues (mail appears when it is sent). The end result was that the Apple Support guys said that apparently it's mainly an issue with users with multiple Gmail accounts and/or with large amount of emails (10,000+). Apple know about it and are working on the fix and I for one can't wait until that happens to get back to the way it was.

Puli0003,

Thank You I own a national IT company and nobody could figure this out good one you helped my company figure this out for a client of ours I dont think I have ever posted on this forum but I would like to show some appreciation your fix simple as it was worked to think we looked over that 5 times.

Hello

I am not sure how your situation differs from the one that we had with a customer but I am more than willing to provide some tech support the easiest was for us to fix your issue or help with your issue is through remote session my company is Geeks For You you can google it to make sure we are legit. Other than that It would be hard without some screenshots.

The easiest way to fix that is if you have an email provider that allows a web interface. If so go to your email servermvia your browser, use the web interface to delete the broken message. Good luck.

Dear MyLuxLife, you are a genius! Your solution fixed my problem also. Thank you.

I was having the same problem as listed in the original post. Highlighting the mail account and selecting "Get Info" with a right click showed all the new messages on the server that were not showing up in my Mac mail inbox. I saw one e-mail with "sender unknown". I deleted it from the server and all my new mail showed up right after the deletion. It seems one bad e-mail on the server can mess everything up.

Thank you!!! After a month of looking for solutions I ran across your comment:

Its a GREAT day now!!

Thank you, thank you, thank you. I've been going crazy with this for weeks now. Same problem. Only one account of three wouldn't retrieve mail, but iPhone and iPad working just fine. Web mail, just fine. Tried absolutely everything. I couldn't actually find any messages on the server that /looked/ corrupt, so ended up just deleting everything in my server inbox. Now it's working properly again, and the mysterious thousands of messages popping up in "Mail Activity" have disappeared. Very pleased. Thanks again.

Fixed this problem on iphone 5.

symptoms...

Can create new and send ( successfully ).

No new email appears - inbox remains empty

email folders all present ( all empty )

tried resetting iphone - no effect

tried deleting email account and recreating - no effect

tried removing iCloud - no effect.

eventually, held finger on inbox for around 5 seconds - everything came back to life.

hope this helps

My problem is even weirder! I can not get Mail to show a particular email, but others are appearing. The email I am expecting is from a trusted source and I have had no trouble receiving it in the past until today. It has been sent to two different addresses of mine, and I can see it on the servers when I use "get info".

I am able to download it to my iPad, just not to my iMac. I have tried all the solutions mentioned here, except removing the com.apple.mail.plist preference because that file does not appear in my library for some reason.

Any ideas would be welcome.

Hi Gary, have you tried this?

Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.

(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive & clear caches.)

Restart & open Mail, highlight that account & chose Rebuild from Mail's Mailbox menu item.

If that fails...

Make a new Smart Mailbox that only includes Unread Mails, do they show in that Smartbox?

Thanks BDAqua but that didn't work. I set up the smart mailbox as you also suggested and the email did not appear. I can still see it on the server and I have received all the other emails shown, just this one email doesn't want to get delivered. Weird!

It is a test email I created myself from a Wordpress blog that I have and I have always received them in the past, so it is not a "spam" issue.

WordPress has big security problem, google is blocking 1,000s of WP sites... might your DNS servers be googles?

To go back to the original posting:

We had this same problem today on a new iMac running OS X Yosemite. Clicked on Get Mail, got the sounds of new messages, then nothing in the inbox. Even messages that were there before were gone. We couldn't find them in any other folder. However, the Flagged folder did show the flagged messages that had been in the Inbox, but we couldn't move them into the Inbox (drag and drop, but nothing showed up). The mail was coming from a POP account at Comcast.

Here is what fixed the problem: We did a hard Quit on the Mail app (hold mouse button down on the icon in the tray; a menu comes up; select Quit). Then restarted Mail and all Inbox messages were there.

Anybody at Apple know what causes this? Is it on the bug list to investigate and fix?

If it is on a list to fix somewhere, it won't get fixed for 10.5, likely not even 10.6/10.7, most often I'd say it's caused by Directory or file corruption, or even stale cache files, sometimes a Rebuild if the Mailbox will help, especially after doing a Safe Boot to correct things.
