The folder inbox is full, and can't hold anymore messages.

This dialog box now appears when I try to open Thunderbird to retrieve my emails.
"The folder inbox is full, and can't hold anymore messages. To make room for more messages, delete any old or unwanted mail and compact folder." How do I expand the folder? Where is the folder, how do I find it? I have already deleted a large amount of old emails and compacted some, but the message still comes up.
Thanks, Robert

  • I guess this is because of the 4gb limit of Thunderbird folders, probably after deleting some emails and compacting the folder the problem should be solved.

    This is how to compact the folders:

    And if this still doesn't work you might want to try deleting the index files:

    This behavior seems to be the result of a corrupt Inbox file. My Inbox file was over 4 GB, but after fixing it, the size came down to under 2 GB. Here's what what worked for me:

    1. Go to the Thunderbird mail folder, find the Inbox file, and back it up just in case something goes sour. Look in Tools>Account Settings to see where the mail files are located.

    2. In Thunderbird, move all mail from Inbox to an empty mailbox (I made one called InTemp). If there are many messages this can take quite a while; this would be a good time to go to lunch.

    3. Close Thunderbird.

    4. Go to the Thunderbird mail folder and delete the Inbox and Inbox.msf files.

    5. Start Thunderbird. The Inbox will now be empty.

    6. Move all messages back to the Inbox from where you put them in Step 2. This will take a long time too (coffee break?).

    That's it. If you navigate back to the Inbox file you will see that it is much smaller than when you began.

    Note: It might be possible to skip Step 6 by renaming the the mailbox file from Step 2 to Inbox, but I didn't try that. If anyone does, I'd be pleased to know if it works.

    • I am trying to follow your process, but need more advice please. How do I move the messages from my full Inbox to an empty mailbox? I have many folders in my inbox. And then if I close Thunderbird, how do I go to the Thundervird mail folder and delete the Inbox and Inbox.msf files? thanks, Anne
    • Anne, these procedures have been largely superseded by bug fixes. Please create a new support topic. here http://getsatisfaction.com/mozilla_me... because it is hard even finding your comments in the middle of a year old thread.

  • This is the message I started to get in /tools/error console. I have tried other suggestions, reduced huge amount of stored messages, less than 300, I created new folder, moved all messages as above but when I try to get messages, I still get the same, even after updating Tbird AGAIN/

  • Bruce, Why did you post down the bottom of someone elses support topic.

    What you have posted does not sound anything like the original problem.

  • Sorry, not familiar with this. I get exactly the same response as Mr. Riggs when I try to get emails.

  • Bruce, If you are getting an inbox full message, to simply need to delete the inbox file. Move anything you want to keep into another folder.

    Close Thunderbird
    Search your computer for a file simply called inbox. (it is located in your profile directory, but it is probably simpler to just search for it)

    When you find the correct file it will be 4gb in size (or there abouts). Delete the file and start Thunderbird.

    A new inbox will be created when Thunderbird starts.

  • How do you delete the inbox file on a mac? I'm not stupid, but I switched from pc to mac a few months ago, and can't figure it out. I typed "inbox" into the spotlight box and nothing came up. Any suggestions?

    I believe on a Mac, the mailboxes are stored ~/Library/Thunderbird/Profiles/NNNNN/Mail where ~ is your home folder and NNNN is the profile used in Thunderbird.

  • Well, in the instructions YossiD provided, step 4 consists of finding the inbox folder and removing the inbox file AFTER closing Thunderbird. Which means using whatever file browsing tool your computer has. On a PC, its Windows Explorer; on a Mac you would use Finder to navigate to the folder to remove the mailboxes.

    The path I gave above are the folders you would navigate down to get to the mailboxes and remove them. Please note: make sure you copy the messages to another local folder before you remove the inbox!

  • I read your info and it worked! I haven't been able to use T-Bird for months because of the crazy response alert! Thanks so much. One more thing. . . now that I have T-bird up and running, how do I get my gmail.com account to be in my T-Bird browser instead of in Safari as it is now. Hope you can help me - I am really lost (but that's what happens when you are an old(er) lady! LOL
    Thanks again

  • Luckily, this is pretty simple :-)

    There are two ways to download email from GMail - via POP3 or IMAP. Generally POP3 downloads the email to your computer and then removes it from the mail server. IMAP on the other hand downloads emails when you read them (leaving a copy on the server) but requires you to be online to read mail. Since IMAP leaves a copy of the email on your server, you can then use both TBird or login to GMail if you're away from your computer - this is what I use myself.

    First step is to login to your GMail account in a web browser and click on the Settings link (top right next to your email address).

    In the settings page, click on "Forwarding and POP/IMAP" settings. As you see, you can switch POP or IMAP right there. For IMAP, you just need to click "Enable IMAP" and then click "Save Changes".

    Back in TBird, you will need to go into your Account Settings and add a new account. I think the latest version of TBird will pretty much automatically configure the mailbox for you once you enter the email address, but you can always try the manual approach (there's a little link at the bottom of the GMail settings screen with "Configuration instructions" for various email programs so use that if you're stuck).

    You basically just add the account and you're done. Now you should be able to check email in TBird or the GMail web site.

    I also use IMAP a lot on my Android phone for connecting to several non-GMail accounts since they are standard open protocols (unlike MS Exchange).

  • When I get mails, I received the alert that the folder inbox is fill and can't hold any more messages. So I transferred the mails. My inbox is empty now. But I cannot get mails and still receive the same alarm. Please advise.
