Thunderbird Support Forum

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

Hey, I would like to move my thunderbird profile (including all the old emails) from my old PC to a new MacBook. Before I buy the MacBook, I would like to verify that this is indeed feasible. I have migrated my Thunderbird profile from PC to PC and found it very intuitive. Is it essentially the same process for migrating the profile from PC to the MacBook? I assume the folder would be slight different but there will no not be a conflict due to the data format, right? I would be grateful for a brief confirmation / some advise. Thank you! Simon

Been on Thunderbird for about 3 weeks, then didn't open for about a week. Version 115.6.1. When I try to get messages, it gets stuck at downloading 1 of 684, eventually quits. How to fix?

Suddenly I can not receive my emails on Thunderbird. They do show up on my cell phone. When I send an email, I get the following, "Your message was sent, but a copy was not placed in your Sent folder due to network or file access errors. What can I do?? Ed PS I will get your email response on my cell phone, thank you.

I have been using Thunderbird on my PC's for at least 8 years. It has been reliable and easy to set up for use with multiple acccounts. However, in the last couple of weeks it keeps freezing up and the header bar tells me it is "not responding". I have tried closing and reopening the program & restarting my computer, no joy. I wonder if there was an update recently which caused this sudden bug? My current version is 115.6.1

Had to wipe old Win 11 due to corruption. When setting up from scratch, I use 3 gmail accounts. However when I downloaded Tbird, trying to set up myt 3 gmail accounts, Gmail will NOT authorize Tbird. I have tried all advice that I've seen on forums and on YouTubes. None work. Contacting Gmail is impossible. Forums are not providing any solutions. Does anyone have a proven fix? I appreciate your help. Thank you.

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.

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?

Clearing the "Recent" list when attempting to move emails used to be simple. Go to your profile while Thunderbird is NOT running and delete the panacea.dat file. It's no longer there. The only threads in the support forum suggest the same thing, but the threads are EIGHT years old. Where is the list of entries for the "Recents" folder located and how do I reset it. I have more than 20 entries, most of which I've used only ONCE. How to I clear this mess?

I can't find this info anywhere. I had three email addresses. I made several subfolders for saving certain emails under the LOCAL folder. Then I added a couple new emails. All those newer emails addresses are below my local folder (which contains lots of subfolders.) I would just like to move UP my email folders so they are all in a line and I can check all the emails while the LOCAL folder and its subfolders is at the bottom of the list. Does this make sense? I have tried moving it and nothing happens. I guess the word I'm looking for is REORDER. I want to reorder my folders. Thank you. (I collapsed everything to make it easier to see in the picture.)

About four days ago my email froze & asked for my password to activate imap.mail.yahoo.com. Everytime I enter my password it flags failed & asks for retry or new password. Finally I went directly to the yahoo mail site & logged in with the exact same password. If it works on yahoo mail but not on Thunderbird (anymore) I am at a loss. Can you help me? Thx, Doug

Thunderbird opens and is permanently trying to re-open a previous tab, with the oscillating dots. It will not respond while trying to do this. How can I close this tab?

I need to send a libre office calc sheet by email using thunderbird to a colleague, so she can open it and edit it and send it back to me with her input. Until she is logged onto Thudnerbird, I have tried sending it to myself, but it arrives as a 'read only' document. I am unable to amend it. I have added my email address to Libre office Tools / options/ email and selected File/ Send / email as open document spreadsheet, but it still does not work.

What I am doing wrong here please? I'd be most grateful for any help. thank you
