An error occurred when writing to the calendar Verjaardagen! Please see below for more information.

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.

The calendar is marked as read-only because it contains birthday's and reminders cannot be dismissed.

What is the proper way handle a anniversary calender and reminders?

Incoming emails from a specific source say that my email package can't display html formatted messages. How do I configure Thunderbird to do that? Regards Andrew

I copied addresses to address book which tells me that over 400 items are there but they are not visible. I can delete these invisible addresses one by one even though there is nothing there if I go to edit. How can I make these addresses visible, or what can i do to get rid of them and start over.

To all Thunderbird Tech Junkies -

I have been using Thunderbird for well over 20 years. But, this year it did me in.

My email, john@jtbcpa.com, was hosted by some no name outfit that was poor. It took forever for emails to send, and I could not update away messages..

I asked my internet guy to move my email from the old profile to gmail. I was hoping to keep my same profile and email on Thunderbird, without having to change to either Outlook or some other software to run email.

So, my internet guy moved the john@jtbcpa.com to Gmail. However, once he moved the email Gmail, Thunderbird, gave me several problems - as follows.

1. No matter how many times we tried to add the new email address to Thunderbird, it could not find the server. We tried multiple gmail settings. No go.

2. I am not the experienced in updating computers, but I had updated email on Thunderbird many times before. For both new accounts, and new computers. It took time, but I made it work. I could always find the files in the profile folder that I needed to copy and move.

However, the new Thunderbird would not allow me to go in and manually alter settings when it was looking for the john@jtbcpa.com account on Gmail. Thunderbird kept telling me it could not find the account on the server. And, manual setup was not available on the updated Thunderbird software. Why????

3. The email works fine when you go to the GMail web site.

4. Since I needed a better platform than the GMail website, we were able to load the john@jtbcpa.com email on Outlook. However, I did not have all my email addresses. (after 20 years I have about 2000 email address.)

5. I thought I could export the email address from Thunderbird to a CSV file and maybe load them into outlook. However, when I went to export, there was only one option to export and that was to export everything. Which included thousands of old emails and addresses from various email accounts. That was not going to help. What happened to the export tool which would download or export your email addresses only?

So, I have to look at the old emails in Thunderbird to get the email addresses.

I am not sure why the update to Thunderbird is so limited. I have loved the program for many years. It was easy to use.

And, I was always able to get all previous email addresses to work.

In conclusion, I am not sure why Thunderbird cannot recognize my john@jtbcpa.com account. It can see my other two gmail accounts, brozowski99@gmail.com and john@johncpa.com. Maybe the person who upgraded the account put some sort of block on it through gmail. I don't know.

I have spent hours on this transition, which should not have taken more than an hour. And, I even offered to pay someone to call me to help me with the platform. This is where internet online services and AI are useless. I need a tech savvy Thunderbird expert to call me, go on my computer, and make it work. But, all the responses I got was - "We will not do that."

So, I am forced to move to Outlook. I am not happy, and all the old emails will remain on Thunderbird.

I know the software was free. And, I was happy to pay someone to get it to work. Or, maybe look at my gmail settings to see if there is a blocker preventing Thunderbird from seeing the account.

No need to respond - I just needed to vent.

I installed a new version of Thunderbird for my wife because her version was very old. I deliberately installed the new version in a different directory than the older version. The mailboxes seem to be in the appropriate directory but they are not displayed under Local Folders. How do I correct this problem? Thank you. Geoff

All of a sudden, this error message started popping up every time I open my in box. Please help: What is the problem, and what can I do about it? I am not expert enough to figure out what I must do just from reading the error message. Image below. Thanks.

Hi. First off, a BIG thank you for all the hard work you have put in and now give it to us for free to use. Your generosity is mind-blowing. I am using TB on Linux and Android. My email life depends dramatically on the use of aliases. When I send mail luckily TB let's me "customize the from address" and I can use anything my email provider allows me to use. That's fantastic. But there is a bug. When someone replies to my email and I hit reply to answer their reply, TB PUTS THE WRONG EMAIL ADDRESS INTO THE FROM FIELD. It puts the main email address, not the aliased address the email I am replying to was sent to. Once I did not pay attention and hit send - and my cover was blown. My main email is for no one to see, just the aliases. Please, PLEASE fix this bug. When replying to an email, the from should ALWAYS be the address it was sent to. This is really important and if you fix this, as far as email goes, my life will be perfect.

On the Android version,, things are much harder. Itis impossible to compose or reply to aliased emails so I can only use it for reading.

I believe that if you fix the alias issues, for people whose email provider allows aliases, email usage patterns will truly be revolutionized. Thank you

I'm not sure how to word this correctly, but I'll try. I write into a news site, in their comment section on a regular basis. And for years I've gotten responses from other readers on a very regular basis. In other words.....I read and article, and then I respond in the comment section, (in this case it's Newsmax) and more times than not I get a response from another reader. This has been going on for years. Now all of a sudden I don't get those responses. And I would notice, because more times than not i get angry responses from readers who vehemently disagree with me! I wrote to Newsmax to tell then of this problem....they checked, and found what I needed to do to correct it. I did. It must have been some glitch along the way, to change the way things were.

Anyway....I made the changes necessary, and that mostly had to do with making sure their "no-reply@newsmax.com was added to all of my address books, and wouldn't make their way to my "junk' folder etc. When in fact, while checking my address book and junk folder etc, those missing responses never made their way to those folders. They were nowhere to be found at all. So their other direction was to get in touch with TB and find out from this end what might be wrong! So that's what I'm doing. I miss bantering back and forth with other readers and commenters, but no matter what I do I can't get a response! Any help figuring this out would be more that greatly appreciated!

Thank you,

Michael

Many messages have suddenly disappeared from local folders. But not all folders were effected. I compacted and repaired some of the affected folders but messages did not return. I deleted the .msf file for some and restarted TB. No effect.

I'd appreciate your thoughts.

Thanks, Bob

When I am composing I want TB to recognise the different address books I have when I type the destination name(s) in the To: bar. when composing the email. I have several different address books. I could do this in when using W10 but I have just moved to W11 and imported the old address books, I note that on import they have a slightly different directory structure (they are no longer sub-directories.) - they are directories - see images attached (W11...).

Now compare that with the W10 image (file W10...) and note the difference.

There were no instructions about getting W11 into W10 structure and no warning about the consequences of not doing this. Presumably there is a method - but I didn ot find it on the change over.

I cannot just move the directories around in the All Address Books pane which is what I expected to be able to do.

The Capture file shows TB on W10 picking up the RSSNI_LGC address book when I have only typed in RSSN

Please advise as it is currently a pain in the rear.

Best

Having updated to 140.2.1 there are two Outboxes in my local data. They are both named Outbox but one refers to a location of "Outbox" and the other to a location of "Unsent messages". The former is the location where messages to be sent should go, the latter is the location used in previous versions of Thunderbird. Unfortunately Thunderbird is putting messages in the latter. Not only does this mean that my Thunderbird does not match the documentation but also the Send Later addon uses the former and is therefore not working. This seems to be an error in the update process. How can I get Thunderbird to use the correct location ("Outbox")? I can find nothing in prefs.js that relates to the location of the Outbox ... surely it can't be hard coded!

Hello,

I have had this Yahoo account from the days they were only starting to provide free mail boxes. For the last 10 years or more I have never actually connected to my account on Yahoo, but only through Thunderbird on my PC and another mail client on my smartphone.

Few months ago the email client on the smartphone ceased connecting to the Yahoo account: it started redirecting to a Yahoo page to enter login credentials, which I did but then would tell me that it needs to confirm it was really me and send me a verification code to a recovery email. I don't have that email anymore, so doesn't help me. I don't have my phone linked to my Yahoo account either (that was the only other option they suggested). So I left it alone since I had no issues keep using my mail through Thunderbird.

However, today Thunderbird started doing the same - it is redirecting to a Yahoo page which after asking for login information, is sending a verification code to the recovery email which I don't have access to anymore.

There appears to be no way to contact Yahoo at all. The only way is the paid support which I opted for, but the automated answer I got was that the Premium support was not supported in my area and I had to go to online resources.

Everything is linked to this email account of mine. I must find a way to regain access to it. Please help me.

Greetings,

I am currently having inconsistent results sending mail.

I can send an email from my IMAP Webmail interface but sending the same email from my THUNDERBIRD POP Desktop fails.

The error indicates that the SMTP outgoing connection from the host has timed out...

I have tried to check the mail host ports and they are all open ... e.g.

Test-NetConnection tulip.bradmark.com -Port 465 Test-NetConnection tulip.bradmark.com -Port 587 Test-NetConnection tulip.bradmark.com -Port 25

Is there a THUNDERBIRD configuration that might be affecting this?

I do realize that when you send an email there might be several hops and failure points and I can't help that, it is the nature of the internet.

Howerver, this looks more like my local configuration/network?

Thank you.

Jean-Pierre

PS I have temporarily disabled my firewall and VPN for testing, it has made no difference.

Heya I just downloaded and supported Thunderbird as i was super excited for a new email client however it won't open at all. The icon bounces for a few minutes and then it crashes and needs a force quit. I attempted to open in troubleshoot mode but it didn't. I've restarted my Mac and still refuses to open. I also have uninstalled and redownloaded Thunderbird. I'm currently running Catalina 10.15.7 on a MacBook Pro (Mid 2015). Any help would be great. Thank you!

How do I disable the donation webpage that opens (in Thunderbird) automatically?

A common suggestion is to disable the start page: https://support.mozilla.org/en-US/questions/1226585 https://support.mozilla.org/en-US/questions/1520014 https://support.mozilla.org/en-US/questions/1515838 https://support.mozilla.org/en-US/questions/1507571 That option is already unchecked.

Some seem to be suggesting that this page opens when an update happens: https://support.mozilla.org/en-US/questions/1512477 There was no update installed lately.
