Thunderbird Community Forum

Hi, it's many year that I moving manually messages to folders located on a NAS. Everything has always been fine, but today I've discovered that, despite searching funcion is regularly finding all the messages, if I try to open them they show a blank body (see image attached)

I exported a address book from Mailbird as vCard to my desktop. When I import it to Thunderbird it appears with most of the entries blank. The profiles that do appear all have missing data, such as phone numbers and email addresses. This happens with 3 different address books from Mailbird. Malibird only allows export to vCard. It also happens with a older CSV, Excel file I have tried. I am using Thunderbird 139.0.2 (64-bit).

I wonder if there is a way to make Tasks in some online calendar to allow syncing? I like the way thunderbird can show its tasks on calendar view, it's great, but it would be perfect if i could sync such tasks to online calendar. I know that probably there were providers for google/outlook (not updated to 139 yet), but I am a bit afraid of them because of full access permissions.

thanks a lot in advance! Thomas

Have 5 email addresses with 2 different servers on my Thunderbird account...2 addresses with "maine.rr.com" and 3 with "gmail". Have no problem with the "gmail", but if try to make a "reply" to any "maine.rr" mail it is "server" rejected with message to "check SMTP settings AUP # Out-1500 and verify email address is correct in account settings". Have gone to account settings but cannot find. How so I resolve?

just open Thunderbird on 23-Jun-2025, and just can see "inbox" and "deleted items", all of others email box are lost!! even "outbox" can be found! EMAIL: COMPMANY VERSION OFFICE365 EMAIL But my persional outlook email is ok in Thunderbiard.

I asked our company IT, they did not change any setting in office365 email server. At the same time, I re-set this email in Foxmail, it's ok too and can see all of email box. or do Thunderbiard not support office365 company email any more?

Hi. I opened up thunderbird and I've got no messages in my Inbox. My other folders have stored and other messages. I can't see any of my inbox in the trash, junk etc. Don't know where they have disappeared to. I just sent a test message to my email and it appears to be working. I'm just missing my inbox saved messages. Any help appreciated.

Hi all,

Filtering has always worked fine for me until recently. However, over the last few months I've noticed that any new filters I've setup don't work. Existing filters continue to work fine.

I've checked to see if there's an update but apparently I'm running the latest version: 128.11.1esr (32-bit)

Any ideas?

Thanks

When I try to delete a message from my inbox I get a message which says "cannot comlete this task because another operation is using this folder" how do i solve this ?

Thunderbird keeps getting stuck, both when I'm writing mail and when Thunderbird tries to copy mail to sent items. I get the message "Thunderbird is not responding". What is the problem and how can I solve it?

I have combined thunderbird and gmail, and it works different at my 2 pc.s, but that is ok.

But my original thunderbird relays on yousee and the adress from yousee.

What if I skip yousee?:

Can i still keep the email address from yousee to continue this combination?

I want to keep it, (the adress) if possibly, but not yousee??

This is the question ?

--,

Other words, not questions:

I must say: The configuration and the userfriendly way Thunderbird runs at pc is the very best - also the way You can mail to a group and answer between each other and all ( not easy in gmail)+ the way you can make maps= The worlds best.

But there are too many problems with yousee at the mobile, therefore I am thinking about shipping it.

( I also have Thunderbird at my mobile, but some new spams here, which does not shows up in Gmail or Thunderbird ...at pc.s) --- Best from Denmark/ Kib

'Encountering 10 -15 minute delay in receiving emails in Thunderbird via Yahoo mailbold text. My ISP is Cox communications and with their conversion to Yahoo, using Thunderbird to view emails has not been timely.

Greetings, I have Centurylink for my Internet Service Provider. They provide my internet service and email. I have been using Thunderbird for many years and know it quite well. My issue is this. About a year ago Centurylink had a major update with it's services. Since that time I've been having issues using Thunderbird for my e-mail. I'm currently using the 139.0.2 (64-bit) release.

Getting e-mail using Thunderbird is very slow and sometimes nearly impossible. I have to open the Centurylink e-mail and get caught up on e-mail using their e-mail service. They also want me to start paying for the e-mail service through Centurylink.net services.

Another anomaly is any sent messages I send using Thunderbird will not post to my Sent folder in Thunderbird. I use IMAP because my Desktop and Laptop share the same e-mail so I can have those readily available on each. I have been through all of Thunderbirds settings multiple times chasing a remedy to these issues without any results. This is very frustrating!

If I delete my e-mail account from Centurylink.net and attempt to use Thunderbird solely, would this be something you would suggest? I'm not familiar with how to SAVE Thunderbird e-mail files when changing ISP's or where the information is saved. That is very important to me before attempting too many changes in trying to find a temporary remedy to these issues.

I'm trying to hold out for any big changes for another year, due to getting fiber brought into our area and access provided to all customers in the next year.

I'm very excited about Thunder having e-mail provided exclusively. However, not seeing any target dates for this service, I'm trying to put off having to jump through two or three changes until our fiber is available.

Any help and suggestions would be greatly appreciated! Thank you in advance for the help!

PS. I have just donated another $20.00 toward Thundermail and Thunderbird Pro projects.

Hello,

I've been using Thunderbird for a number of years on my Windows 10 computers (one at a time). I used to have my email hosted by Cox, but it moved to Yahoo a year or two ago. At that time, I changed my IMAP and SMTP servers from cox to yahoo.

Suddenly, the other day, I'm not longer able to send or receive email messages in Thunderbird. I can still send and receive at Yahoo.com.

Here's the setup that I've been using in Thunderbird:

Incoming Mail (IMAP) Server

Server - export.imap.mail.yahoo.com Port - 993 Requires SSL - Yes

Outgoing Mail (SMTP) Server

Server - smtp.mail.yahoo.com Port - 465 Requires SSL - Yes Requires authentication - Yes

When I click on my inbox, I get a dialog box that says:

"Login to server imap.mail.yahoo.com with username davidmorrison@cox.net failed."

Maybe I should set up another account, with my same name?

Appreciate any help you have!

PS: I DO donate every year or two to Thunderbird...

Thanks.

Can I have my Thunderbird email account on my desktop computer and on my laptop simultaneously? I want to continue using my desk top computer for email, as I always have. But I also want to take my laptop with me on a cruise so I can send and receive email while I'm away.
