I have for a while been getting popups that TBird is unable to write email to a mailbox.

'Unable to write the email to the mailbox. Make sure the email system allows you write privileges, and you have enough file space to copy the mailbox'.

I saw that at least one other person reported this, and the suggestions included:

1. Rebooting. Done, no effect. 2. Antivirus interference. I am using standard Windows antivirus. Have been using same for years without issue.

The problem does not appear to interfere with writing to mailboxes. Seems to be an erroneous popup only.

I have loaded thunderbird and the email preview pane is not displaying. It was OK this morning but has disappeared now. Is this a temp[orary issue or has there been an update of the program.

Since awhile while, the items I send, don';t show up in the sent folder of that account. The complete folder is empty, which means that I also lost messages. I didn't make any changes to the settings, it might have happened due to an update maybe?

My other accounts work still fine. I checked all settings I could think of that might affect it, but haven't found a solution. I'm getting pretty desperate and hope someone can help me out.

It's an IMAP account. I've selected the 'sent folder' in subscribed. 'When sending messages, automatically' the 'place a copy in' is checked and directed to the email address. Also tried it with checking 'other' and select email address. I also just tried to 'local folder', but nothing happens.

I hope my description is fine. If more info is needed to tackle this problem, I like to hear!

I am losing my Mediacom ISP account (which I have had for 20 years) at the end of this month. I have used Mediacoms web mail server all this time and want to keep many emails and addresses that are on their server. I was told that Thunderbird would allow me to transfer/copy these messages to my computer and retain them there in Thunderbird after I no longer have access to Mediacoms server. I have installed Thunderbird 3 times and spent 2-3 days with help from this forum trying to gt it to work properly but have not succeeded. I have a windows 10 HP laptop and am not completely computer literate so I don't believe I will solve this by myself. I even loaded up an old windows 7 computer which I did with ver 15. but that didn't work either. THe one difference I did notice is that the Tbird auto installation on my Win 10 machine selects POP and on the Win 7 machine it selects IMAP. Mediacom is uses IMAP

Get this error message I think since the update on September 2nd. See below

Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox. Also, I downloads a few old emails from September 2. If I delete them, they re-download when I click on get mail. I do get mail on my phone and on the Xfinity web site. I really would like to get this fixed as soon as I can. Thanks, William Dudzinski - <redacted>@comcast.net - <redacted>

I have installed Thunderbird with Zorin 18 and it won't show contacts. Google says that Thunderbird has full access to contacts. Attempt to manually add contacts fails with message of "Can't connect to server". I did have to manually add the calendar to make that part work. Is this an uninstall and reinstall (Thunderbird that is) situation?

Thanks for your help

Hi, In profiles, I have several, many of which are up to date and 2 are large, one which is meant to be my current profile at about 2.5 Gb and another at 3.6 Gb (plus others of about 50 Mb) - see screenshot. What is going on?

I have followed the directions at https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer#thunderbird:mac:tb146 several times but only one acct is transferred and NO local folders. I am going from Thunderbird 146.0.1 on a Windows 11 PC to a Mac Mini M4 running Sequoia 15.3.1

After many years of using Thunderbird with an AOL account I changed my password in AOL to increase the security. So I had to install the AOL account again in Thunderbird. I created an app password in AOL and put it in Thunderbird. Everythin fine so far. AOL login window opens automatically. But after login to AOL the message "somthing went wrong" and "try on anther device" pops up. I tried it on several PC's - no way. Other mail clients like Mailspring oder Mailbird did work with the AOL account. What is the problem?

Each time I start TB, I get this message: "The folder 'Inbox on redacted@aol.com' could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again." What does this mean and what can I do to fix it. Thanks. M. Campbell

I am getting the following error message in Thunderbird. Unable to download email to mailbox. Please make sure that the file system has write permissions and that there is enough disk space to copy the mailbox. Write permissions are available and there are 735 GB free.

I get a message trying to access my account: Kunne ikke skrive mailen i mailmappen. Sørg for at du har skriverettigheder til filsystemet, og at du har nok diskplads til at kopiere mailmappen. This is in danish so I hope You understand. But how to solve this issue? I can not receive mails because of this. Best regards Poul Kristiansen

Dear Sir or Madam,

I have lost all stored folders with my email correspondence from the Local Folders for an unknown reason (I restarted my computer, and they disappeared). I can find some of these emails using the search option, but I cannot see the path of their storage location. I have checked my Profile/Mail/Local Folders, but they are not there. Are they stored on the server? How can I recover these folders?

Thank you very much in advance,

Jasmina

an year ago on 11/25/24, I have raised this same issue https://support.mozilla.org/en-US/questions/1475852#question-reply Another user https://support.mozilla.org/en-US/user/davidsk/ replied that it is a bug ! I still have the same problem !!

My hard disk is again almost full. And it is primarily Thunderbird bloated folders.

In the MAC hard-disk, size of the many of the folders stored in local directory, are much larger that the size on TB.

For reference, On TB, "_cc folder" is 2.0 GB On Mac Finder, "_cc folder" is 13.63 GB

I have right-click the folder and press "compact". The folder on TB reduces in size. But, the folder on the Mac harddrive does not reduce in size.

Thunderbird 115.4.1 (64-bit) on macOS 26.1 Server Type : POP Mail Server

Appreciate help to get this fixed.

Thanks Attached screenshots

My Thunderbird inbox stopped accepting messages with a message 'Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox.' I 'repaired' the folder but all my junk messages suddenly reappeared in my inbox (a lot of them!). Tools didn;t work (wanted to re-apply junk filter). Went into safe mode - no difference. Now can't get any tools to work on the inbox folder. Not sure what to try next. Help much appreciated.

When I receive a newsletter from my club, it doesn't show the pictures. It does describe the picture and warns it might be AI generated. If I reply to the email or forward it, the pictures are displayed. I suspect this might be a settings problem. The original email includes:

[image: A picnic table and benches on a stone surface AI-generated content may be incorrect.] [image: A group of people dancing in a room with lights AI-generated content may be incorrect.]

[image: A person and person standing next to a vase AI-generated content

may be incorrect.] [image: A person sitting at a table with food on it AI-generated content may be incorrect.] [image: A group of people sitting at a table with plates of food AI-generated content may be incorrect.]

[image: A group of people dancing in a room with lights AI-generated content may be incorrect.] [image: A group of women posing for a photo AI-generated content may be incorrect.] [image: A group of people standing in a room with lights AI-generated content may be incorrect.]

Can anyone shed some light on this?
