Mail - IMAP problem accessing inbox

I have the very same issue here, the very same description. I'm using the same OS version and the same mail version, on Mac Air though.

I had multiple email accounts right now, some of them are yahoo accounts, all working but only one of the yahoo account is not working, its working though at my iPhone, but just not here.....seems to be a new issue i cannot find anything about it online. How many threads required for Apple support to reply in here!!

Wish to hear something from u guys.

Best

ok, I've been doing some digging in here, and I managed to find out some logs that might help.

This is from the email account that is not working;

The other set of logs are from the account that works;

some how I'm sensing an issue with that UID flag. not sure if I'm correct, but I feel that my mac is not setting it write while sending the request, and then it can't find it when receiving the reply.

Same here.

I installed the latest 10.10.2 beta just a couple of days ago, thought that this was the problem

for me not receiving mail, but then I looked at the last received mail and that was a couple of

days before I installed the latest beta.

Something has change somewhere, it's easy to blame Apple, but I think Apple is not at fault

here.

Reason is that nothing in the System (OS X) changed, this tells me you have to contact

Yahoo.

Gmail had it's problems as well with Apple mail, Google changed something back then, I heard

they don't use standard IMAP protocols and that's why many people got into problems receiving

mail, guess it's the same here.

I also get my mail on my iPhone 4s, just not on my Mac.

Later I will try to boot into an earlier version of OS X, should not work either if the problem lies

within Yahoo's servers.

Just to add another point, same symptoms (empty inbox, no ability to rebuild - greyed out, yet email inbox is OK in the web view via my.yahoo).

I've tried to:

rebuild (as stated above cannot as the menu is greyed out)

go offline and then sync

delete the mail envelope files

delete the inbox plist file

delete the Yahoo account and reconfigure it fresh

delete ALL my email accounts and reconfigure then fresh after a restart.

Sorry to not have solution. Still have an empty inbox even with hundreds of emails (some unread) visible via the web view. The other folders are OK (junk, sent etc).

A tip: I created a new folder via the web view and moved some emails from the inbox to that new folder; and those emails (and the new folder) then became visible in mac mail. So inbox email can be got onto your mac that way if desperate.

It looks like something to do with the yahoo inbox has changed in the last few days and is no longer syncing properly with mac mail. That is a major problem for Yahoo and perhaps Apple also.

Thanks, I was able to transfer my emails to a non-inbox folder.

I have another peculiar problem besides this. My separate yahoo ID does not have this IMAP inbox problem; I, therefore, tried to keep all the settings similar but unfortunately, this did not work.

I am almost convinced it is yahoo, I created a new folder on yahoo's website in my mail, I

then moved the unread messages from Inbox to the new folder.

Next I checked email in Apple Mail, they got through, moved them to the inbox in Apple mail

which also worked, deleted a few and they got deleted on my Mac and on Yahoo's website.

I quit mail then opened it again, still in inbox on my Mac I saw the content not loaded in 3

mails in Inbox, but when I clicked them they got loaded.

All a bit strange to me, but I am quite confident it's a Yahoo issue, as I told in my other main,

nothing changed on my Mac, it just stopped about a week ago.

Wow, I am having the exact same issue. I am running Mavericks. I was going to update to Yosemite because I am desperate, but it does not look like that is the solution. I even created a new user on the system and simply added the Yahoo imap account to Apple Mail. No luck. I see stuff in sent items, but nothing in inbox. Mind you, this is after the application teases me by showing activity with thousands of messages coming in. Makes me wait until it finishes, then shows nothing!

I hope we get a solution soon.

Mehrvarz. Seems to me Yahoo is the problem, you are on Mavericks and have the same issues, if

that's the case it's not Apple which is to blame.

I agree JustPerry. Yahoo is silent on this matter.

the same yahoo account is working on my iPhone though....not really sure its apple issue or yahoo....how to reach them? are we expecting apple response in here?

I have the exact problem since few days ago. I have several computers and Yahoo IMAP mail is working still fine with OS 10.9, iPhones and iPad, just not working for Mail is OS 10.10.1.

Even the Sent folder is still in sync but the inbox seems to have problem

Resolved!

Had the same issue - no new mail coming in and after deleting my Yahoo account and rebuilding indexes along with lots of restarts, I had nothing in my inbox in mail on my Mac. Other folders were fine. On the Yahoo web interface all folders including the inbox were fine.

I got it working but can't claim credit for the solution My son saw somewhere else that someone said they moved messages out of their inbox and mail started coming in. I had about 7800 messages in my inbox (on the Yahoo web interface, hover mouse over your inbox to see that number). I created a couple of new folders and moved messages out of the inbox to those folders (I chose to do it by date). I was left with about 3800 messages in my inbox. I had already exited mail and removed the index files ("envelope index" in Library/Mail/V2/MailData) and restarted everything. Viola!

BTW, I am at 0.51% of my 1TB quota on Yahoo. I am running OSX 10.9.5. Also, before moving messages to the new folders, I tried adding my son's Yahoo account (about 1,000 messages) to my Mac mail and it worked fine. My mail has been uninterrupted on my iPad (iOS 8.1.2) and my Android phone (4.4.3 using the most recent K-9 client).

Conclusion - there may have been some limit imposed on the number of messages in the inbox, although I cannot rule out the possibility that it is the size of the inbox that is at issue.

Sadly this does not apply to me. Yahoo imap messages are not showing up in Outlook 2013 or Apple Mail in Mavericks.
