Thunderbird Support Forum

I have been using Thunderbird for a year. It is ok, but some problems are borderline un-tolerable. I have ~3500 emails in my IMAP account. I would like to keep more for a deeper search, but ok - I could handle that. And once in a while, about every month, I am doing something and the Thunderbird decides to re-download all my messages. And it locks me out of all emails for about 2 hours while this process is ongoing. I cannot open emails, I cannot answer - nothing.

I have no "cleaning" software, I do not mess up with the database file.

Is there a way to avoid this re-download? If not, is it possible to avoid the lock-out, to get emails usable while it does it - for example, download the most recent emails first and make them visible at least?

I'm trying to send a reply e-mail and I get this message. "Sending of the message failed. A certificate that is not yet valid was used to issue the server's certificate. The configuration related to smtp.gmail.commust be corrected." What must I do or what can I do?

It seems that e-mails from one particular e-mail address, solidifi_values@solidifi.com are being blocked or filtered out as spam. I need Thunderbird to recognize this address and allow all e-mails from this address to be delivered to me. This is the second time I have posted this request. I would very much appreciated it if someone would call me @ 530 412-2260 or respond via e-mail to hartleyappraisal@mindspring.com

Hello, Linux environment is running on my chromebook, thunderbird has been installed. 2 issues: - When I try to install an extension, I always get a message "This extension will have permission to have unlimited access to thunderbird and the computer". and I'm stuck. The add button does not trigger any action. This does the same thing if I want to install a dictionary from the settings. - I have no access shared folders like my Drive on my Chromebook, despite having Linux sharing enabled. Thank you for your help Céline

I have Thunderbird on two PCs. Thunderbird stopped working on my older PC, Lenovo Z40, Windows 10. I uninstalled Thunderbird on that PC and tried to reinstall. I have downloaded the set up file, but when I open it tells me I need a Microsoft safe app and sends me to Edge browser. I looked at help website but can't see how to overcome this step to get to what is described on the Tunderbird UTube video. I have downloaded the Thunderbird set up file using Edge, Chrome and Firefox browsers. Same problem each time. Thanks

Internode have stopped providing email services, and are using The Messaging Company. I want to re-estiblish my Thunderbird account that I was using previously. Can someone explain (simply please) how to re-activate? Many thanks Sue

As of today, I can no longer send or receive emails in Thunderbird. No settings were changed. I checked and everything is set up the way it should be. Bluehost also confirmed it all looks good.

SO WHY DID THUNDERBIRD DECIDE TO STOP WORKING TODAY? Fortunately I can still get the email within Webmail, but I prefer not to do that, since all my folders aren't set up there. Any ideas what caused this and more importantly, how can I fix it? I do have the latest version of TB.

The images show that it just sits there for a long time trying to send and then the other shows the resulting error message.

Hello,

I run a. Thunderbird v 78.14.0 (64-bit) on a Macbook Pro 13"mid 2012 with Mac OS 10.10.5 (Yosemite) b. Thunderbird v 115.5.1 (64-bit) on a Macbook Pro 15" mid 2012 with macOS 10.15.7 (Catalina)

How do I make happen, that I sync the calendars in both Thunderbirds constantly, i.o.w. instantly (like for example the iMAP emails do)??

I find the option for new calendars: "On the network" ... Which network is here meant??? In the help there is not much info about it. I am not using and will not use Google or any kind of "social media" (!)

Can I use my own homepage host (which has some webspace left) in order to sync? Or for example an online storage like mega.nz ?

Or could the both macs just sync the thunderbird calendars just via WiFi/WLAN directly (AirDrop ?) or via Bluetooth ??

It would be so great if calendar sync would be as easy as the emails do!

Thanks for you advice!

Best wishes, Thomas

how do i review my previous questions on the forum? I am not seeing any responses to my questions and wondering if it is me. for example light screen and dark screen, how do i adjust it?

I'm not sure where to put this post. Sorry.

I don't have a lot of internal hard drive space and want to have Thunderbird store emails to an external hard drive. So, I have a few questions about this.

Q1: How do I do this? I saw a procedure on a non-Mozilla site and it seemed questionable to me. So I thought it would be best to get the procedure from here

Q2: When I move the files (not copying them) will this impact the emails online (Gmail and Yahoo)? I don't want to accidentally delete them from the server

Q3: I am concerned about the following scenario: I tell Thunderbird to use the external drive. Thunderbird starts to download emails to the external drive. What happens to the emails that are on the internal drive? does Thunderbird move them to the external drive? Or will I have to move them manually? Can I safely move email folders on top of folders of the same name without messing anything up? (I'm concerned that Thunderbird would not know that a previously downloaded folder exists and would start to download it in the new spot. So when I move the folders from the old spot to the new spot, it would overlay the new copy and I don't want that to mess anything up)

I hope my questions make sense. I'm not always clear about how I ask things

I just updated Thunderbird. So, I'm running the latest version. I'm using Windows 10 (old computer)

Thank you MistWing

I am receiving the following message: The RETR command did not succeed. Error retrieving message. Mail server.comcast.net responded: Message 9 expunged.

The message number does change each time I try to download my messages. Thanks for any help. Rob

One of my 3 emails is not downloading after not being on computer for 2 months.Other 2 work fine. On settings for that account the syn in the menu is not showing? Shows on the other two. On start up it downloaded messages but they don't show? Several had some malware that my antimalware took care of. Messaged downlload just fine on my phone for that account.

I think I have been scammmed I was sent an e-mail that appeared to be from cogeco.ca my provider stating that I needed to update otherwise I would no longer be able to get into my email account. I updated and now cannot get into my email I can get into everything else using firefox but not email, please help me. Thanks

Hello, I moved Thunderbird data to a new computer according to your instructions via a USB drive On the target computer everything goes well until point 9 of your instructions. "Choose to replace your current data when prompted." However, this screen does not appear. I open Thunderbird, but then only the screen to enter the email data appears. So Thunderbird does not open with complete data. What do I do? I'm wrong.
