I have Thunderbird v140.3.1esr (64-bit) on Windows 10. I made a new calendar based on a google calendar. I have 2 google calendars so I am trying to import the second one from an .ics file exported from Google calendar, but each time I try it gives me an error message.

An error occurred when writing to the calendar MyMotog! Please see below for more information. Modification_failed If you're seeing this message after snoozing or dismissing a reminder and this is for a calendar you do not want to add or edit events for, you can mark this calendar as read-only to avoid such experience in future. To do so, get to the calendar properties by right-clicking on this calendar in the list in the calendar or task view.

It has installed itself as a second calendar in Thunderbird, but I've no idea why I can't import the one into the other?

I have a new laptop "YOGA" with W11. Now I want to add an extra e-mail address. I am in Sweden and now I want to add my Spanish e-mail. It is a " @telefonica.net" address. I only want it to receive mail, to send mail I use my ordinary swedish mail. When I put in the "@telefonica.net" Thunderbird will not respond it says "use only letters and figures etc"

How can I fix this?

I've been trying to add yahoo account for several weeks, I type in the email address on the add account function and then I just get a wheel of death and have to force shut the programme, I'm on windows 11.

My Thunderbird was not finding messages that I could see were there.

I followed the advice here https://support.mozilla.org/en-US/kb/rebuilding-global-database.

I deleted the (large) global-messages-db.sqlite (I have been using Thunderbird for a long time - and I am monthly contributor).

The rebuild gets to a certain point and then stops (as indicated by Tools Activity Manager). Always at the same point. I guess there is a bad message in there somewhere. But now I am worse off than before.

I tried rebuilding several times. I have also compacted the account folders of the account that stopped and then tried rebuilding.

I have many years of messages in there and I need a functioning search. What can I do?

Hello I deleted a lot of emails, and I am not sure if all my old emails have been completely deleted. When I go to open Thunderbird, after about a minute it will freeze up. I have 3 email accounts and I can only view one account but when I try to view another email account, it freezes up, and I have to exit. Before I deleted my emails it all worked great no problems. What did I do wrong and what can I do to get Thunderbird back to working like it use to ? Thanks a lot Sam

I have located the profile on an old computer and want to import it into TB on a new computer. I have copies the "mail" portion but I can't find away to import it into the tb on the new computer. How? Thank you, Paul Marrow

I accidentally discovered that dozens of email messages for a specific period of time (about a week) are still on my ISP's email server. Thunderbird is configured to download all messages to my computer and then delete them from the ISP email server.

Prior to, and since, that period of time (for many years) this has typically worked. Now, however, nothing I do to Thunderbird will get those messages downloaded - I can only access them using my ISP's webmail portal.

Based on web research, I've tried deleting the popstate.dat file and the global-messages-db.sqlite file to try to get Thunderbird to rebuild its indexes and/or POP3 databases to no avail. I've also tried to flag the messages as "unread" using the ISP's webmail portal, again, without success.

Any suggestions?

When new emails come in the emails are highlighted (bold type) and also there is an orange diamond shaped icon in the email entry. In addition, the email folder name font will be blue to indicate there are new emails in the folder.

Mostly this works but some emails are filtered and, although there are new emails in the folder this blue status appears to be lost. Also, the orange diamond signifying "new" is lost too.

The lack of blue folder highlight is definitely the result of the emails losing their "new" status.

It is a little inconsistent until I find a pattern. All I know is the "new" status change is the result of filtering. None of the filters has any action other than "move to...". I never mark as read or even delete them.

Is there any way of checking the email status in the SQLite database?

Hello,

I've been using Thunderbird for years with the same setup: - Windows 10 64bit - Thunderbird always running, with 4 linked mailboxes (all POP), each checking for new mail every 5 minutes - The OS is typically running for a month or longer without restarting (I always hibernate my PC instead of shutting it down)

Everything was working just fine until recently. In the past month (or two, I'm not sure) Thunderbird just stopped receiving new e-mails on 3 different occasions. No error messages or anything, I always notice only when the sender calls/texts me, asking me about an e-mail I didn't get which is very annoying. When this happens, Thunderbird seems to work normally (I can browse all the mailboxes, move e-mails between folders etc.) but it just never downloads new messages from any of the mailboxes (not even when I hit F5 or the "Get messages" button - which normally displays a brief "Host contacted, sending login information..." message in the status bar but does absolutely nothing when this problem occurs). When I spot this problem and kill Thunderbird via task manager (closing normally doesn't help because it will still run in the background) and run it again, it immediately downloads the missing e-mails on startup and resumes working normally. But I'm getting really nervous about possibly missing important message(s) because Thunderbird is my primary (and for 99 % of time, the only) way of accessing my mailboxes (I only login to the web UI when I suspect Gmail or other web hosts to false flag an e-mail from legit sender as spam - but I typically only do this couple times a year).

My Thunderbird is (always) up to date (v 140.3.1esr).

Do you have any idea how to fix this, please? TIA! 🙏

I have installed, uninstalled, and reinstalled Thunderbird four times - and I can NOT get any of the folders from Outlook to show up so I can drag them to my Gmail account. Suggestions??

I've used Thunderbird with the Owl add-on for Exchange/Outlook accounts for several years. Recently I've found when I open Thunderbird on my laptop, a tab opens for each account, apparently showing the Outlook web page for each account. This is great, but on the same version of Thunderbird (140.3.1esr) on my desktop, that doesn't happen. I can't see how to open these tabs there, or even how to reopen one of these tabs on my laptop, except from Go->Recently Closed Tabs. Am I missing something? What controls this behaviour?

I have number of email filters in use. The main set of filters are all configures to "Filters for Local Folders". As I have a Gmail account I have a set of filters set to "Filters for <gmail address>". The Gmail filters always move the emails to my Inbox folder. These are then picked up and moved by additional filters in the "Filters for Local Folders".

Previously this worked well. However, under the latest release 143.0.1 under Windows 10, there are emails left in the Inbox folder which should have been filtered within 10 minutes. Often they are there for many hours before being processed.

When I have unfiltered emails in the Inbox folder, to make sure the filters are correctly configured, I run the "Run Filters on Folder" option on the Inbox folder and it works perfectly.

All of a sudden when I go to check email it wants a password and I didn't know I had one. When I put one in it won't take it. How do I get in to check email. I'd have you email the answer but I won't get it because I can't open it.

I am trying to sign an email with my dsc token. Token contains Digital Signature, Non-Repudiation and E-mail Protection, Document Signing, 1.2.840.113583.1.1.5, Smartcard Login, Client Authentication key usages. Encryption is not required. Only want to sign. Able to see the the certificate in both account setting and thunderbird settings. But still when I select sign and try to send a mail, not prompting for PIN and failing with " Sending of the message failed. You specified that this message should be digitally signed, but the application either failed to find the signing certificate specified in your Mail & Newsgroup Account Settings, or the certificate has expired." error message

How do I add a person's non-default email address to a mailing list?

I have a mailing list for our golf league, and in my address book many of those in the list have both a work and home email address, with one marked as the default. Some of our members would like messages sent to the list to go to both addresses. But I haven't found a way to add a person's non-default address to the list.

Do I need to create two address book entries for each of these people, one for each email address, and separately add them both to the list? That seems awfully klunky/inefficient to me.

Good morning

Thunderbird is not sending or receiving emails, i already deleted the gmail account and reinstalled it but it didn't work upon installation i get the attached message.

this was running on a windows 7 pc with no issues for about 2 years.

thanks in advance

I recently noticed that some of my local folders are missing. Not all of them, but some of them. Following some advice we found in the forums, we closed Thunderbird and then deleted the .MSF files from the Local Folder. When we restarted TB, we had more of the local folders, but were still missing 18 of them in the alphabetical order they are listed in. I created a new profile and copied the local folders over to the new profile. When I started TB using the new profile, there were fewer local folder listed than before. Went back to the previous profile and had the local folders that were still missing 18 folders. I see that there maybe a bug for this being researched as I saw 4 other posts in the forums regarding this recent problem and wanted to get my problem noted also. Thank you.
