From time to time - and for reasons that I cannot discern - I get screens popping up from Google saying that it needs information or permission to access T-bird accounts. I have both gmail and other domain mail server accounts in T-bird.

Today, it's happening again. I can't seem to resolve the issue even though I've been through the process of providing requested information and permissions. I can't get T-bird to connect to servers to look for downloadable messages. This is a problem that is keeping me from using 2-step verification with several websites that I need to contact. I say that T-bird isn't connecting because the messages that normally appear when I request downloads do not appear at the bottom of my screen. The problem started with the first screen below and has now migrated to the second screen. I tried sending test email among my accounts, both gmail and others, but I cannot. As far as I can tell, T-bird is sending the messages to servers but not retrieving them, but I cannot be sure they were sent. As I was typing this sentence the second screen below popped up without my doing anything with email.

I don't recall what I've done in the past to resolve the issue. IIRC it has required different acts at different times. Today, nothing seems to work. If this continues, I'm going to have to find another email client after having used T-Bird for more than a decade.

Can someone please tell me how to get off this merry-go-round?

4 days ago, the calendar app suddenly stopped working. If I try to add an event, it sends an error message saying 'An error occurred when writing to the calendar Sandra Kanfer Clarke! Please see below for more information.' and tells me 'modification_failed' and that '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.' At this point, the calendar switches itself to 'read only' and I get the exclamation mark and triangle saying this calendar is momentarily not available. This is a synced Google Calendar that has been running on Thunderbird for several years without any problems. I uninstalled the calendar and reinstalled it, I uninstalled Thunderbird and reinstalled it - none of it makes any difference.

Trying to send (redirect) a Thunderbird message using Simple Mail Redirection results in an error: "Transaction failed Unauthorized sender address. 1M8Pmu-1u0qJD3qDo-000B18. Please check the message and try again." Is there a fix for this or is there a better add-on for redirecting multiple messages at a time?

Thanks, Doug

I can no longer move emails to the folder of my choice. If I drag and drop an email into a folder it never goes there, sometimes it does nothing, sometimes the email disappears like it moved but it never ends up in the folder I drop it into, I search all the folders I have created and the email I moved is GONE! I look in the "Trash" bins I can find and the email is GONE!

Version 128.8.0esr (64-bit) I tried too update the version that is an exercise in confusion.

Side note, the only way to copy and paste the version number is using the keyboard, if you highlight the text in ABOUT, right click it does nothing! No popup window giving you the option to copy. First time in 30 years I have seen this problem.

Thanks in advance.

2 weeks ago I could send a group email, Now it says not of the form user@host I have an older version 128.8 I believe. The term mailing lists is never used. I have given all recipients the same nickname.

I am not able to send a group email. I was able to 2 weeks ago. The error message is not on the form user@host. I have an older version of thunderbird 128.8 i believe. They do not use the word mailimg list only accounts and I have given the people on the list a nickname and it worked 2 weeks ago

Hi, I recently changed the password of my Google account, and now I am facing this issue where I can't add my account in Thunderbird. I removed saved passwords and also cleared all cookies. I tried to add the account in troubleshoot mode, but the result is still the same. I don't know, but Thunderbird says my configuration was found in the Mozilla ISP database. I am guessing that is the root cause of this problem. Please someone help me with this. I have a lot of emails and uninstalling Thunderbird and setting it up again is not an option here.

I use an AOL email account and Thunderbird on my Mac. In Thunderbird, the junk mail folder - which AOL call "Bulk Mail" for some reason - has moved to the Trash folder and I can't get it out. It's a Thunderbird problem - if I go onto my account at AOL.com, everything is normal. How do I get it out? I've tried cutting and pasting it, creating a new folder...nothing seems to work. I don't want to empty the trash in case I no longer have a junk folder at all

good morning, messagefilters have stopped working on popmail inbox, whether automatically on TB start or even manually. i checked everything, it looks ok but does not work.

this is an additional issue with TB which lately has been plagued with a number of dysfunctions on macos, and this is sad because this was a good reason to stick with you and send you funds to continue.

I have wasted so mch time energy and lost so many mails due to the faulty versions of TB lately that I am seriously considering quitting, and relating/sharing my late experiences on my professional social networks.

what solution do you suggest so that this product of yours finally behaves as it is supposed to.

was great at the beginning, becoming a nightmare. can t cope. regards

I have a correctly working Thunderbird, with around 15 email accounts connecting to different servers, on 1 Windows PC. I moved the setup to a new Windows PC as described here: https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer ("alternative method"). Thunderbird version is 128.8.1esr on both PCs. On the new PC, Thunderbird gives a timeout connecting to any of the IMAP or POP3 servers. I have disabled the Windows firewall and uninstalled a McAfee virus scanner. When I restart Thunderbird in troubleshoot mode, everything works correctly (!). However, when I select "disable all add-ons" and "Reset toolbars and controls" + "Make changes and restart", the connection timeouts again occur. What can I do to make Thunderbird behave correctly as in troubleshoot mode?

The contents of my thunderbird folders are not shown although the number of email contained there is shown at the top oof thunderbird next to the folder's name (see images 1 and 2 for example). When a new email comes I can see it, but after clicking on it and seeing it, it disappears from my folder. Nevertheless, all emails are there because if I go to the troublshouting mode I see then (see images 3 and 4). I do not have any special extensions or themes (see extensions.jpg and Themes.jpg).

Any ideas on how I can resolve this issue? Best, Haris

Hello, Yesterday the Google calendar tab opened with a message and stupidly I didn't read it - I just closed the tab and thought I'd check it later. Then I realised I could neither dismiss TB calendar notifications or snooze them. Next I realised I could no longer add to the TB calendar or delete any items that were already in there. I'm not sure if there has been a recent update which may have brought this about but any help would be very much appreciated. Thank you.
