Hello, I have a problem.

Before an emergency move, I transferred my calendar data from my Windows 11 PC to my laptop (Windows 10). The calendars worked perfectly there; entries were added, etc. Since yesterday, after eight months, I've access to my Windows 11 PC again and am trying to transfer the calendar. It's not working.

Two of my calendar files imported, but my large company calendar file (3200kB) won't.

I now know it's too large, so I tried manually splitting it (using Notepad). Part 1 (500kB) imports, but Part 2 (488kB) doesn't. I also tried using Google Calendar, same problem. However, this calendar file works perfectly on the laptop.

What can I do? It contains data for eight months plus future dates.

Best Michael

I am a club secretary. I want to send a small (under 100KB) Word document, as an attachment, to my committee mailing list of 7 people, which includes myself. I cannot get Thunderbird to do this. I can send the same attachment to just myself (or just my wife) but it seems that when I put multiple addresses, either as a mailing list or individually entered, the email isn't received by anyone. There is always a copy in my sent folder. I am getting very frustrated by this and would appreciate some help. Many thanks, Alan

I have used Thunderbird for many years and and have loved it. However, recently my "Local Folders Inbox" have been extremely slow (deleting emails, reviewing an email, etc.). I have tried every suggestion that I have found without any change: reducing emails in the folder (down to about 75 remaining), compacting and repairing the folder, deleting and rebuilding all of the msf files and global database, disabling all addons, empty trash and junk, clear the cache, disable hardware acceleration, exclusion in antivirus, etc. It has become very frustrating. Any suggestions would be greatly appreciated.

re: OAuth2 Authentication for Yahoo, AOL and ATT

My settings selections don't really follow your help descriptions to the letter,so..., also, I already have 2 accounts on 2 platforms and they seem to already be configured with SMTP outging servers using OAuth2.

I'm confused since I'm now on 140.8.0 and have not needed to change a thing, contrary to expectations set from T-bird app popup warning and Mozilla article.(?)

For the last two days, every time I start Thunderbird, a pop-up requests me to log in into Google Calendar. I have followed what little advice I can find:

• Unsubscribed/deleted all calendars
• Deleted all Gmail Accounts
• Deleted all saved passwords, and re-entered them only for my current email accounts.

How do I get rid of this irritating and unnecessary pop-up? I have updated to v128.14 but the problem persists.

Thanks in advance.

I got a new computer, and after installing Thunderbird, it took forever to get it set up with the information from my old computer. Now, the unified folders aren't working. All of my mail is going into each account's inbox. There's no option to choose anything on the unified inbox, only the same thing as the other inboxes have. Help, please!

On more than one occasion I get the following message after sending an email. I'm told that a copy of my outgoing email has not been saved in the sent box:

"access errors. You can retry or save the message locally to Local Folders/Sent-aidan@clockwork1.plus.com."

Is there any way that I can overcome this issue and have a copy saved automatically, please?

This started last year and I found a fix on google but I can't remember it. It has noiw come back and is driving me nuts. About 2-5 minutes into composing an email thunderbird goes unresponsive and is greyed out. i have waited 30 mintues and nothing happens. It does not happen until after you type the first character into the new email. I have checked user rights on the thunderbird folder and my windows user folder and I have admnin rights on both If i shut Thunderbird the email appears in drafts when i restart, but only from a bit before it froze. I have reinstalled, compacted nothign is fixing it. Using 64 bit 140.3 on windows 11 home.Tried update to 140.3.1esr. no difference. Just about to give up and go to Outlook because I don't write trivial emails and this is a PITA

Thunderbird is what Outlook was striving to be. It looks like Outlook, but out performs every thing I have tried. and it Works!!!!!!!!!!!! Cudo's Love this product.............................................................

I tried importing my Outlook Classic address book. As you can see from the attachment, I really messed it up!. I am not technical at all, I wasn't sure if I needed to import my contacts or my address book. I think, but am not really sure, that I exported my .pst file, address book to a csv vile. Can anyone one straighten me out? If I have to start over, how do I delete the mess I created without loosing all of my other settings? Thank you very much 😊😊😊

Thunderbird 148.0 moved trash folder from top group in folders pane to alphabetical order in lower group. Reopening Thunbird didn't help. How to get it back into place? Thanks!

In the latest version 148, the moment I enter the login credentials for a second Yahoo account and click continue, Thunderbird simply copies the mail folders from the first Yahoo account and does not show the mails/folders for the second yahoo account. This is despite the fact that Thunderbird displays the correct name for the second Yahoo account as well as the correct username for the second Yahoo account in the account settings. I have tried: 1. Setting the 'mailnews.oauth.usePrivateBrowser" to True in the Config Editor. 2. Deleting and adding the second Yahoo account after restart of Thunderbird as well as restart of the PC. 3. Manually configuring the account settings while adding the second Yahoo account.

Please advise what else I can try. Thanks and Regards

I have downloaded Thunderbird from official Mozilla homepage. It seems to be installed correct. I got the icon and a question : should we start Thunderbird now. I answer yes. Then I get the message : Thunderbird is not found ? but I have just loaded it ? I am running windows 11 and I have got newest upgrade.

Hope you can help me out. Thx in advance. Regards Thorvald Antvorskov

PS I also have a PC running Linux Mint. Loading Thunderbird here was no problem.

Rookie move. I deleted a calendar (not realizing that by deleting the calendar, which I didn't use, I was deleting all of my tasks).

Is there a way to restore the calendar?

I received an email with 7 attachments. 2 of the attachments had similar filenames. When I clicked "Save All" the 2 similar filenames were not saved. See screenshots for details

Running Thunderbird 140.6.0esr in Windows 11. This afternoon I found that one of my three accounts no longer shows up in the folder pane, though it still appears normally in the account settings tab. I can still send mail from it, but can't receive any. The other two accounts appear in the folder pane as usual and can send and receive normally.

Any help getting the account back into the folder pane would be appreciated. -- tralfaz

I have been using Thunderbird for ages now with no problem, but I suddenly realised that no recent emails were appearing from my Gmail account. I have tried everything suggested on line to resolve the problem, including uninstalling and reinstalling Thunderbird, and deleting and re-entering my acccount details but neither the IMAP or SMTP servers will connect to Gmail. I have reset all of the server settings on Thunderbird, and have checked that Gmail is IMAP compliant (which, apparently, is is now automatically). I have spent hours trying to sort this out and am just at the point of abandoning Thunderbird completely, but I am loathe to do so if there is a solution. The latest error message i have received is "Unable to log in at server. Probably wrong configuration, username or password" but I don't know what else I can check or change.
