Mail not showing new messages in inbox

Thank you. One other symptom that I hadn't noticed is that after the Inbox messages reappeared we lost all of the messages in the Sent folder (except for one that was flagged). Unfortunately Rebuild and Safe Boot didn't solve that problem.

We are new to Mac and so I'm surprised that this type of problem (serious, possibly connected to lack of robustness in the file system or mail database file) has been reported over several years with no reliable fix from Apple. We can be critical of Windows for lots of things, but I never lost an email message.

I appreciate your taking the time to try to help.

Yes, it's pretty sad, though it affects a small number of people, it doesn't help those people. 😟

If you'd like more help on this, I recommend starting a new topic so we can narrow in on your details. 🙂

Thanks for the suggestion. The problem was fully resolved by calling Apple support (we're still within the 90 day free phone support window). I found Apple support to be excellent and I learned that Time Machine is integrated with Mail so I was able to recover the entire Sent folder from before the time of the problem. Once you know how to do it, it is very easy. I'm just glad I set up Time Machine with an external disk to store the backups.

I am also having a similar problem, i use a gmail account and for some reason I'm not receiving them via the apple mail application i have to manually visit my gmail account online and look at them. whilst it isn't a massive problem it would be much more convenient for me to use the application in the first place, can any one help?

Thanks

I am experiencing the same issue. I have more than one gmail account I pull into my mail.app. One works fine, the other is missing all the messages with the label "important". This just started happening in the last couple of weeks. Gmail is set up through IMAP. Because I have multiple accounts, this is a major PITA!

What is "Connection doctor"?

Any ideas?

Thanks for the response, BDAqua.

I checked connection doctor and it says everything is connected properly. I also did a rebuild, but that did not help. It's only some messages that for some reason don't come through. And it doesn't limit itself to certain senders, meaning that I'll get some messages from a sender, but miss others from the same sender. There's no pattern to it. Very frustrating. Hmmm...

I have 2 iMacs on my desk - I recently started working from home. Both macs are running the same OS 10.11.6 and both running the same version of Mail 9.3.

On one mac the emails come in normally with no problem. On the other mac, try as I might, nothing in my inbox. Emails are coming from work so its a Windows 7 version of Outlook. But why OK on one mac and nothing on the other?

I have tried 'Rebuild' and the Connection Doctor says everything if fine. This is very frustrating.

Hello, thanks for the solution. It worked for me.

Same story here : a corrupted message that was perfectly legit (from our Head of IT Dpt, lol!) from a webmail point-of-view. This message made all the later messages never show in Mail.app although the activity monitor was indicating that an ever-growing number of mails were incoming.

I tried the rebuild feature, cleared the cache but only deleting the corrupted message made everything work fine again. However, I still have a popup window asking for the password of another mail box. Even if I enter the right password, it is rejected. It is not a big issue as mails from this mail box are received anyway.

Hi Klaus1, I don't get the purpose of your message: my problem IS the same that is related to the topic, I applied one of the proposed solution and it was SOLVED. I don't expect any further help from the community. I also don't understand why you had the feeling that more than one question was asked in my post: actually, there are NO question.

My goal was to thank (a lot!) the community and share what worked and what didn't work so that people having the same problem can get an answer.

Regarding the software version issue you raised, it seems that this particular problem is not specific to MacOSX 10.5 (as the original thread is related to OSX 10.5). PaulHibbert even posted a message involving a more recent MacOSX 10.11. I browsed the community forums but never found a thread as relevant as this one. That's why I did not create a new thread.

Finally, I updated my info as requested.

I am having this same problem but it is from my work email using an outlook.office365.com server, not Yahoo. Any ideas of what to do? I tried the searching for server unknown in the account info, but that does not show up. All emails show on my iPhone and iPad, just not on my mac mail. Thanks for helping!!!

I'm having the exact same problem (outlook work account), emails show in iPhone and iPad. The problem is on both my desktop (iMac) and MacBook Pro and they are running different OS's. The problem started at the same time (July 31) for both. I've tried some of the above options (rebuild mailbox, delete library file) but no luck so far. I'd love to hear possible solutions.

Even though the original post is 7 years old, this problem persists. With me, my desktop Mail works fine for awhile, then I stop getting messages through my iCloud account. No indication that new emails are waiting (like some others in this thread), it just goes silent. I get emails on my iPhone and iPad, but not on my desktop. If I quit Mail and relaunch it, emails that I missed show up, but still no new ones. The only solution that has worked has been deleting my iCloud account in SysPrefs > Accounts and re-creating it, which is a huge PITA. Sometimes, the fix holds for a few months, sometimes only a few days. #$%&#*!!!

I am having the same problem after upgrading to 10.13.2. Two interesting twists to this: 1 is that the headers of the e-mails show up, but not the body. They *do* show up if I create PDF of the e-mail and open that. Second, when I tried to follow advice to replace my com.apple.mail.plist it was nowhere to be found, not even in a Spotlight Search. Any ideas?

Good point, however I have 20 messages in my mailbox. :)
