Hi,

Scenario: I have a custom domain with an email address, and have used mailbox.org and currently icloud to host my email. In both cases, the email address associated with my custom domain is the only one I use for everything, such as email, calendar, contacts, etc (x@er.com). Also in both cases, there is also a login email address to the email hosting service (i.e. x@mailbox.com and x@icloud.com respectively).

Issue: My calendar invites erroneously send from my icloud email address, rather than my custom domain email address. This appears to be by defaul and unchangeable. See 1/2 screenshot.

Settings: I'm on W11 Pro, using TB 115.10.1 (64-bit). For calendar settings, see 2/2 screenshot.

Background: With both providers, my calendar invites initially were being sent from the correct email address (x@er.com), but inexplicably switched to the being sent from login email address of the email hosting service after some time (about a year with mailbox.org, and a couple of months after migrating to icloud.com). This messes up my calendars, and I need to resolve it. Hopefully it's just something dumb that I'm doing.

What I've tried: On mailbox.org: When the issue first occured I put up with it for a few weeks then assumed it was probably mailbox.org and migrated to icloud. This appeared to resolve the problem at the time. On icloud, my calendar sync was setup in TB using add-ons, which worked for a couple of months and then the issue recurred. I've tried: 1. In apple account settings: I tried changing my apple-id to be my custom domain email address, rather than my icloud email address (didn't fix it). 2. I then unsubscribed from all of my network calendars in TB, removing the addons and restarting TB, as per https://support.mozilla.org/en-US/questions/1406255#answer-1568028 - I had to add a blank local calendar first before I was able to remove all of the network calendars. 3. I then added my calendars back into TB by using the direct URL locations, as per https://support.mozilla.org/en-US/questions/1406112 - when adding the calendars back, I tried using the login as both my custom domain email address, and also my icloud email address (didn't fix it).

Any help would be much appreciated.

Thank you.

For months I was experiencing the problem of "Thunderbird not responding" occasionally. It was a short duration issue (a few seconds to a minute). I reinstalled Thunderbird several times without success. I read almost every comment available online about this problem and I tried many ideas and recommendations I found without success. Most recently the problem became so serious that it was not a nuisance any longer. It was nearly impossble to work waiting for minutes to open an email or to continue typing while preparing a message and being interrupted by the problem I am describing. I ran Thunderbird in safe mode and determined that none of the add-ons is causing the problem. I turned the firewall OFF and determined that firewall was not causing the problem. I then decided to run Thunderbird in Offline mode and found that the program works normally. Then while in Offline mode I decided to download more messages and the program asked me if I wanted to switch to the Online mode. I said yes. New emails were downloaded and without going back to the Offline mode I was able to work normally without any occurrence of the "Thunderbird not responding" problem. I have been using this workaround for several days now. I download a number of eamails. I try working in Online mode and I cannot do it. I switch to Offline and work fine. I switch back to Online mode and I don't see the problem any longer for the whole day. Do you have any idea as to the origin of my proble? I am running Thunderbird 115.10.2 64 bit on Windows 11. I had the problem originally using Lenovo T490s and more recenlt Lenovo X1 Yoga

Hi, I am trying to login to my emails and after entering my password the following message comes up message comes up. 'Login to server mail.optusnet.com.au with username dianne.hill failed' Can you please help me?

I filter messages to move spam to my trash folder. I don't use the spam & junk functions.

I'm on some oddball's list who sends all their spam in bold italics and an uncommon font.

Easy to spot but it's easily 30 a day. I'd love to filter them. I don't see a 'by formatting' option.

Any ideas? Thanks!

I added a PNG picture as a background to my emails. Instead of a single background picture, it produces a collage (can't think of another word) of multiple copies of the same picture. Any way to just get a single picture?

Created several email mailing lists. Stored them in the Personal Address Book (PAB). I'm sorry, but Thunderbird doesn't seem to work like any other email client. How do I address an email using one of those mailing lists in the PAB. Tried typing the whole name of the mailing list in the To: field. Didn't work. I'm not entirely stupid but it doesn't make sense to me.

I mistakenly moved a folder into another. It is now a subfolder and I want to move it back. The move command is not working. How do I move a subfolder back to be a primary folder?

Has anyone found a way to have a separate "reply signature?"

The use-case is that I may send an initial email with a 'complete' signature (first name, lastname, email, phone, etc.). But when the other party replies it would be nice to then reply to that with just my first name. Or at worst, auto-insert the full signature.

I've setup my full signature and auto-populates when I create a new message. But not on the reply.

Any suggestions?

I can receive emails but cannot send. The error message I get when sending emails. This began as of the most recent Thunderbird update:

Sending of the message failed. An error occurred while sending mail. The mail server responded: <mjndoug22@me.com>... Relaying denied. IP name possibly forged [70.109.132.97]. Please check the message recipient "mjndoug22@me.com" and try again.

I tried to attach/imbed a screenshot of my SMTP server settings but your Browse button below won't allow the paste.

Hello and Good Morning!

I need to transfer messages from one computer to another. I follow your instructions - export to .zip, file smaller than 2gb. On the second computer, I import the .zip file, the import seems to be successful, then I restart the program and I don't see the imported data anywhere (only Local Folders is created, but it is empty).

Could you please help me? Will be very, very helpful ;)

One of my calendars is not syncing. The same account (O365) also is not syncing the sub-folders.

Not sure what setting may be off.

I added some events from Outlook for Android on my phone sync'd to the same account. But they don't seem to appear, although they are on Outlook Web Access on the browser on my Windows machine.

Hello, I would be grateful for help onm the two following problems in Thunderbird. 1. When someone sends me a web page link, I click on it and get the error message 0x80070057. I have tried the suggested solutions in regedit but it does not work. 2. When I buy something on ebay they send me an email confirmation with a picture of the item purchased. When I go to print it the image disappears.

I am losing what hair that I have left as I am a senior citizen.

many thanks in anticipation. kr David

Hello Thunderbird users!

Today my father lost all the sub folders below the folder Archives. Doe anybody know how to get them back?

I tried the following:

• Clicked on Folder Modes -> All Folders
• Tried the solution mentioned here: http://kb.mozillazine.org/Local_Folders

The strange thing is I also don't see any .sbd or .msf files, with one of the names he mentions, under the directory Mail (in the profile directory). How can they suddenly disappear or be deleted?

If someone knows how to get the folders (with the e-mails) back, that would be very much appreciated!

Within last 2 to 3 weeks I noticed that when I click Get Messages the momentary line of text at bottom-left typically says "there are no new messages", or the "number of messages" about to be downloaded. (This is not the notification window at lower right.) Recently the number of messages actually received is not always correct. For instance, this morning the message was clearly "downloading messages 3 of 3", but only one appeared as a new, unread message in my inbox. This has occurred several times, sometimes qty is correct, sometimes not. My first question is whether this is a bug in Thunderbird, or something I need to pursue with my email provider? Second question: I am only requesting those for my account, but might the "missing messages" be downloaded for my wife's email?

If missing messages are for my wife how do I fix it so I only download mine? She doesn't have admin rights and I made no changes to our account settings. If missing messages are not hers then I am seriously concerned about this issue.

Hi,

Would appreciate your help with the following: New, unread emails arrive mostly with blue bolded text and a small yellow circle on top left of each message, however some emails arrive with black bolded text without the small circle. If I click the download (cloud) button all unread blue bolded text emails turn to black bolded text. This doesn't appear right.

How can I make all new, unread emails have either bolded Blue text or Black text (I would like to choose desired option).

Thanks

Hi,

When viewing an email thread, I see all "copies" of an email, like label folders. (See image)

How do I remove all these duplicates?

Also, on another topic, when I forward mail from one account to another (so that I have that mail in both accounts) - and I have both accounts configured in Thunderbird - the second (forwarded) mail generates a notification sound - but no notification popup. Can this notification sound be eliminated (like the msg display popup does not happen)? It is useless.

Thanks!

As of this morning, I'm unable to click on links in emails and have the URL open in my default browser. When I click such a link, the menu bar darkens as the mouse button is down, and lightens when the mouse button is released. Nothing else seems to happen.

I hope you can help; this is a major problem.

Hi Everyone!

I am currently on Thunderbird 115.10.1 (64-bit) and for a few days now, I can't open the calendar tab. The "Today Pane" is working and showing events though.

When going to "View" the items "Calendar" and "Tasks" are greyed out though.

Any idea on how to get the calendar back? The company will move us all to Exchange and Outlook soon, so I thought I might "survive", but it is pretty impractical have to open my calendars separately in the browser. You only notice how often you use something, when you don't have it. ;-)
