Unable to view Inbox sub-folders in Mail on OSX Mavericks

The problem isn't just in Mavericks. We have noticed this problem (along with many others) for a long time, several OS versions back, with Mac Mail communicating with Exchange and no one seems to have an answer for any of them.

I just Rebuild my Mailbox and everything showed up fine.

Worked like a charm. Thanks.

This has plagued me since 10.9 and still isn't fix in 10.10.1. Geeez. 😐 The WAR of adding a 2nd account works but the moment I delete the account I am back to not being able to access sub folders under Inbox.

Just now I want into the Exchange web app and out of frustration I created 3 new empty folders under Inbox. When I started up Mail.app, it shows all the sub-folders now! Let's hope this "fix" fixes it for the long term.

I had the same question but found it! Feeling accomplished today. On Mail screen, click Show. A side menu should appear with your mailboxes and drafts and junk, etc. Then at the bottom of the side bar is a triangle icon pointing down. Click this and the triangle points up revealing all of the subfolders from your inboxes! Hope this makes sense and helps everyone!

This is really an atrocity in Apple Mail with Exchangel. I had the problem when first updating to Mavericks and all was working for the past year using Yosemite. Now all of a sudden the subfolders in Inbox have gone away again. I've reinstalled the OS X and that didn't help. I've deleted the Exchange account three times and that didn't help. I'm going to try and recover from Time Machine but this is really ludicrous. I hate to say it but Outlook 2011 never has had this problem.

Reindexing does nothing to solve this problem.

I have solved this problem by just adding the same email account again to "Mail".

In "Mail" go to File > Add Account and insert the same email address you're using. Then the same account will be added with all sub-folders.

hope this helps

I had the same problem and I solved it. Try one or both of the following solutions:

1. Try going to your "exchange server webpage" on a separate browser. Log in with your username and password (as well as domain and all the required stuff). Once logged in, create a New Subfolder on that browser, and then move an email from your Inbox to that new Subfolder. Give some time to the Mail App to refresh, and all your subfolders should reappear again.

2. On the Mail App, go to Menu >> Mailbox >> Rebuild. The selected mailbox will be rebuilt and messages/emails from the server re-download. This should fix any issues, although it is some type of Reset (which I avoid doing as much as possible).

Hope this works!

I've had this problem as well for at least two versions of OSX. My subfolders were working fine and then all of a sudden one day, they were not showing. The message were all still there though. You could see this by doing get info from the main inbox folder. It comes up with all the subfolders and the message counts of each subfolder. Also Outlook for Mac was working fine and the messages were all there.

I tried clean install of operating system after wiping out disk and it didn't help. I called Apple and the answer was to add another account, like a gmail account. BTW, this was only happening with my Exchange account. That worked but I found it to be really annoying to have to do this. I switched to using only Outlook, which is very slow in sending messages.

I then updated to El Capitan beta and it worked for a day; and then bam....all over again. Did a recover from Time Machine to two days before and then Mail was working fine...and has been for a few days now. Obviously still not fixed though. This really is an atrocity that Apple hasn't fixed this yet.

I also hate that there's a limit to the size of an attachment that they don't mention anywhere. Now you can get around that with iCloud or some other way, but I have no problems using windows and sending a file of any size.

Yesterday I tried to move a file from a Finder sub directory to trash. I was given no indication that this did not work. Since then I have been experiencing Finder not displaying folders in most sub directories. Purely as a last resort I went to "Empty Trash". I then gpt a window showing the folder I moved to trash yesterday STILL being moved after almost 24 hours. It gave me the option to "Stop" the action which I took but it did not stop! I also cannot Restart or Shut Down because Finder is performing this action.

Any ideas please?

I never noticed this problem but realized that since beta-testing Outlook 2016, I changed my workflows into using sub-folders under the inbox for certain mailer traffic I don't wish to have in my inbox. In OWA, I never gave it a thought that I needed to pay attention to where these folders were placed. Since Outlook 2016 is now released, I went back to using Mail and had this happen multiple times this week. I could see the sub-folders but they appeared empty even though the unread count was there on each folder. I followed the suggestion of moving these sub-folders back to the root of the e-mail account and all the content appeared. Earlier this week I removed the Exchange account and added it back and this did it as well.

I don't mind the change in the tree structure because in Mail I use the bookmark function along the top of the application under the favorite icon panel and traverse my folders there as opposed to the side pane showing the folders. Works fine for me and takes me back to a similar bug I discovered a few years back with sub-folder and Exchange and Mail.

I came across this problem today setting up a Mac for a friend and I realized that I was just doing it wrong. We were looking for the subfolders in their Gmail account but I was expecting to see them mixed in with the Inbox, Flagged, Drafts, etc. I didn't pay attention to the "Gmail (645)" text just below archive. However, if you hover over the inbox name with your mouse it will reveal the "Show" button which will display all the subfolders for that inbox.

Again, likely not the bug that all of you are dealing with but perhaps some of you are as prone to making this error as I was.

This is a mail bug. What you have to do when using Exchange is to add another account to your computer. You can add an icloud account which you probably don't use anyhow or a gmail account or whatever. Once you add the account it will also show up in apple mail and all of your sub-folders will now appear under your main account. I can't believe they haven't fixed this yet.

Thanks a lot, the screenshots really helped!
