Mail not showing new messages in inbox

On your Mail application go to inbox and click on the mail account icon while pressing the control key. A pop-up menu shows up and select at the bottom "Get Account Info". A window shows up. Select the file "sender unknown" or "unkown sender" and remove it from the server using the button at bottom on the right side of that window. Then close the window and cick the icon to get new emails. All the remaining email on the server will be moved to your Mac email account.

My thought exactly.Check your storage quota.

jkrosado, how many files do you have in your Yahoo Inbox? If you have mail going back to 2011, I suspect it's quite a bit of data. A large Inbox often equals trouble. Mail servers are not ideal places to "store" data.

Suggestion: View all the emails you wish to save in Apple Mail, or other email client, and drag them into a folder on your desktop, thus saving them on your hard drive. You can always use a Spotlight word search if there's an email you wish to reference. There are other solutions, but this one is easy.

Hi, Puli0003. Thanks for your reply -- this is guaranteed to not wipe out my emails that are on Apple Mail?

Also, Charles Long, i tried dragging and dropping and it doesn't seem to be possible? I don't think I have too many emails on the server -- I just cleared out a lot of emails (about 15K -- I know, ridicuous!) and still no emails are coming through...?

Thanks!

This is sounding more and more like a Yahoo glitch. To toubleshoot the issue, use another email client/app (there are free ones available) and see if the problem persists. That will tell you a lot. If the symptoms are identical in both apps, you know the issue is likely with Yahoo.

Also, if the drag & drop method doesn't work, you can select mulitple emails in Apple Mail and use the "Save As" command to save one large file to your hard drive. This is kind of a pain, but Spotlight will find keywords in essential files and at least you haven't lost all the data.

In future, try to purge all your Incoming mail folders regularly and save important email to "On My (Your) Mac" in a "Saved" folder, or by project/subject. Good luck. Let me know what transpires.

Ran the account info as puli0003 suggested and even without finding a sender unknown message this sorted the problem. New messages which had been refusing to appear in the inbox finally were shown after 3 days of no email being visible despite the mail activity box showing the new messages downloading. It took a couple of hours for the "messages on server" box to populate with all my yahoo emails from as far back as 2010 but this seemed to sort things out.

I just started seeing the same thing. My Apple application has an IMAP account set up for a GMail account. In the global inbox at the top, an email I received just now doesn't show up in the global inbox. But Apple Mail does show it in the IMAP inbox of the GMail account. I have to scroll down the pane of inboxes to see it.

I'm not comfortabile using the process to rebuild my inbox as a standard resolution to this kind of thing.

@Apple - please fix.

Grump.

Mobilemobster,

Have courage. The rebuild is a simple process, and I've never lost data. As long as you have a Time Machine backup you're in good shape. If you don't have a Time Machine backup, this is good motivation to do so. It's worth its weight in gold.

Hi mobilemobster, I shared your same concerns and (no offense, Charles Long), but I went with puli0003 and it totally worked without doing anything to my actual mailbox - just deletes the messages that seem to be keeping the rest of your mail from coming in. Highly recommend...

Hi BBCarmi,

It sounds like you might have a larger underlying issue. Are you having issues with any other app/s? Are you running the latest version of Mountain Lion? Have you reparied your disk permissons lately?

Apart from this computer launching every program I had running the previous day, unprompted, no.

I have performed the work arounds, rebuilt the mailboxes, restarted Mail, restarted the computer. Run disk utility. But still have intermittant issues with the mail not displaying in the view window. I can double click on the mail in the list and it will open the email in another window, but this is not how Steve Jobs intended Mail to work, unless you wanted it to.

Something new is happening and I would like to see it fixed.

Thanks for your advice!

Hmmmm. If none of the workarounds have fixed it permantely, I'd seriously consider a reinstall and certainly an OS Update to 10.8.4. (There are lots of little fixes in every update.) Then I'd dig around in the Library and System folders and remove any old artifacts from any pervious OSs in the Library/Application Support/Apple/Mail folder.

I still suspect it may be a deeper issue. I had bugs in both Lion and Mountain Lion until I removed all the old PowerPC apps that were not "Universal" or "intel." You can determine this by going to "About This Mac" under your Apple Menu, choose "More Info" and then choose "System Report." In the left column, under Software, choose "Applications." Go thourgh each one to determine that "Kind" is either "Universal" or "intel." If it's not, use Spotlight to find and delete it. Warning - If you're using older software, this action is likely to disable some of it.

I know all this is a hassle, but it's better than doing a clean install, as far as I'm concerned. Good luck. :-)

hello,

similar issues and more than i can figure out:

have 2 gmail accounts, one using my domain as the subaccount. i am able to send (swoosh) from my macbook, but the gmail email ends up nowhere, but does land on the gmail server as SENT mail, not in my inbox. on my mac it shows tha tit was sent in my sent folder, but WHERE did this email land? i've tried enabling/disabling POP (it's an IMAP acct.), no filters. have rebulit mailbox. nothing.

as well, the google mail interface ***** and is awkward. my mail lands in ALL mail, not the inbox, and i'm unsure how to change that. settings doesn't seem to have an option for incoming mail landing in the INbox.

Thank you puli003... I have been trying to fix my emails for days... Apple Support couldn't even help. My mail activity box was showing mail downloading but no appearance in my inbox. Went to the "Get Account Info" and sure enough the "unkown sender" was there.. As soon as I removed it from the server all my emails loaded into the inbox... Again thanks for posting...

I was having this same issue on my iMac, OS Mtn. Lion, and iPhone. Turns out, with the help of some of the info in this thread, I discovered I had an email in my inbox on my mail server with a back slash in the subject line. It was not coming into my inbox and keeping all other emails after it from coming through. Used the "Get Info," deleted the offending email, and all of my messages came in. Thanks to all for the suggestions.

I have been having the same problem usig MacMail. I got so frustrated that I decided to use Airmail. I have not had any problems with Airmail. But, going back to MacMail, the only way for me to get new messages is to close MacMail and reopen it. The problem is that not getting new mail happens so sporadically that I can't seem to find out what the problem is. It will happen sometimes at home but not other times; sometimes at the university where I teach but not other times and sometimes at my office but not other times. I use two gmail accounts and one exchange account. When this problem does happen, it affects all three accounts at the same time. Oh, and this started when I upgraded to Marvericks. I have the most recent versions of both the mail and Mavericks. Very strange.
