Thunderbird Community Forum

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.

Whenever I forward an email, I end up with two copies of the forward in my "Sent" folder. I can't be sure, but I think this behavior started recently and has not always been the case.

New email and replies do not create duplicates.

Is there some setting I can adjust to stop this happening? Thanks.

Been getting a bunch of this, usually in my TB TRASH folder, I think from the Outlook online server.

The server couldn't retrieve the following message:

Subject: "<Removed for PII>"

From: "Not available" ("Not available")

Sent date: 10/31/2024 2:25:02 PM

The message hasn't been deleted. You might be able to view it using either Outlook or Outlook Web App. You can also contact the sender to find out what the message says.

I have 2 personal email accounts: Outlook and Gmail. My client is Thunderbird. Running Win11 25H2. Far as I know, problem began recently. This is a screenshot of some messages from TBirds TRASH folder.

User's image (In images) Thunderbird just tried to fetch emails. Got a notification that it could not get messages, this time from GMail.

What does this mean? Outlook/Gmail servers or Thunderbird? What do I need to do?

Hello,

I use macos sonoma and my email provider is hushmail.com . I have version 115.18.0 (64-bit) of Thunderbird.

I would like to get emails in Thunderbird as soon as they come. What setting should I use?

I tried - Server Settings -> Check for new messages every 0 minutes.

Lately, in the last 3-4 days, it has been really weird, the emails don't arrive in the inbox automatically. Just to give you an example, I looked in the inbox at around 9:00am and I had to click the download button (the one with the cloud) and I got messages that arrived around 7:30am.

While writing this message I just upgraded to version 140.6.0esr (64-bit).

Thanks

Using IMAP deleted items remain greyed out. Have tried all suggestions: emptied trash, repaired inbox, checked subscriptions, set expunge. Nothing worked. Am I missing something? All help appreciated. Don't think AOL server is removing the deleted items.

Why are older emails disappearing from the Inbox? It didn't do this when I was using Windows 7SP1. Now I have Windows 11 and it seems the Oct and Nov emails I had have disappeared. Only Dec emails are in the Inbox.

Discovered no mail download ( auto or manual) into tbird fm Jan1st, ( 146 updated mid Dec)

As others already reported eventually determined due some interaction with email virus checker (AVG) HoweverTbird not useful or helpful in providing to user any indication of problem or providing failure info.

Issue showed as 'Get email' not doing/showing anything - not showing pop3 login+download steps or anything else.. - saw one timeout popup wdw but usually nothing..

Error console showed an error message that "pop3 socket closed will not send info".... fine sfaigoes but have to go look for it.

Downgrade tbird version (145) even tho 146 working for 2 weeks before stopped) - same issue/problem (as per error log)

Direct access to server showed server end closing socket due multiple concurrent sockets open, indicating tbird and AVG.. reset AVG and reboot and restart and (145) now loading but....

Issue is that tbird should be presenting some failure indication to the user on socket connection failure ( wdw popup or message line status - where shows 'making connection";, "login, ...It doesnt show anything... so silent failure.... Just doesnt work ...

Unrelated but should also mention that error console display of 146 prior to above 'pop socket close' msg also shows failure of verification of a tbird extn due missing manifest file... There was only one extn in the extensions dir so Its that one (supplied with 146 installation) - clearly named with a random collection of alphanumeric and hyphen chars...

Cheers

I am using Thunderbird 140.6.0esr (64-bit) desktop on Windows 11. I have multiple email accounts setup, two of which are Yahoo accounts. On 12/21, one of the Yahoo accounts stopped delivering messages to Thunderbird from Yahoo while the other continues to download them. Thunderbird does logon to Yahoo for the account in question and gives me a message that there are no messages to download. When I logon to Yahoo mail through a browser, there is plenty of mail that has been received after 12/21 which should be downloading.

Both of the Yahoo accounts are setup exactly the same... POP Mail Server pop.mail.yahoo.com Port 995 SSL / TLS OAuth2

Outgoing server smtp.mail.yahoo.com Port 465 SSL / TLS OAuth2

I removed the password from Thunderbird for the account not delivering mail, re-entered it, restarted Thunderbird and got the same results. I changed the password (through yahoo mail), entered the new password into Thunderbird and got the same results. I also tried restarting Thunderbird again after entering the new password which made no difference.

Any help and suggestions would be greatly appreciated.

Thanks, Lew

Filters *unreliably* sort the mail into their target files. I have reconstructed the filters from scratch twice, both times with identical, unpredictable results: each filter works properly on the inbox when tested, but each filter only works *sometimes* in the normal course of getting (IMAP) and sorting mail. When getting a batch of mail, some messages are sorted, while others are not. When testing the same filters on the same (still unsorted but already picked up) messages, those same messages are recognized and sorted correctly. The question is: Why are the filters not working reliably during message pickup?

The mail server is running "Debian stable" Dovecot. It seems to work well; I'm not *missing* any messages, but they're not always getting into the right folders. Instead, some messages, and sometimes quite a few messages, may remain in the inbox. I surmise that the problem is in Thunderbird, where somehow the downloading process somehow undermines the sorting process. A queuing issue? A communications-with-Dovecot issue? (The server is in Paris and I'm in North America, but there doesn't seem to be any undue latency that I can detect. The server is not very busy, that's for sure.)

In case it helps: I filter mostly on `DKIM-Signature`, `Authentication-Results`, and `Received` header entries. In a couple of cases, I use `Body`. I'm almost always using "match any" (as opposed to "match all").

Hi, I have been using Thunderbird on my Windows PC for many years. I installed Thunderbird on my Android phone recently but it doesn't work, no emails are seen, and it doesn't seem to collect new ones either. What steps do I need to take to fix it? Regards, Paul
