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!

Im using Thunderbird Beta release. Starting last week, my PC would become extremely slow, to the point it would nearly come to a complete halt. After digging around, I realized it was due to excessively large Thunderbird NSTMP files that were being created. I would delete them and the speed would improve. But then a while later, the NSTMP files reappear and gobble up all my Harddisk again. Part of the issue is the sheer large size of the file, which will consume all available space on my HD, which at present is 600GB. But it also eats up all my RAM so my system slows down til the NSTMP file is fully built.

I use this as imap with Gmail installed on a PC with a 1TB SSD

Today after my pc started slowing again, I started poking around and noticed my main Inbox is massive, 29GB, which there is no chance its that large. All Mail is only 1GB to give perspective

This has been going on about a week.

I tried repairing my inboxes and other folders, but that does not seem to have helped.

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 have reviewed the previous forums on what changes to make to the outgoing stmp for outlook and have implemented them however, I am still unable to send emails. Please see attached for the edit smtp settings I am using. According to the forums these are the correct settings. The only difference is that I don't seem to have the ability to set authentication method to login as that is not an option for me.

What am I missing?

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.

I have a new laptop & I've downloaded Thunderbird & logged in. It doesn't have all my old emails & folders in the new one. How do I transfer all the old emails & folders from the old laptop to the new one? Or is it a settings issue I need to go into on the old laptop to make it so they appear in the new laptop?

I have come across an issue when replacing hyperlinks in emails.

The scenario is: I have an email that I have sent that includes a link (a zoom meeting).

I wish to send a similar email so I go to my sent items, find the previous sent email, and highlight, copy and paste the contents of the email that was sent to a new composed email.

I then copy the new link, highlight the existing link and paste the new link in its place.

I then confirm that I have the correct new link showing - I can see the meeting number within the link and it matches the new link.

However after sending the email, it is then converted to a hyperlink, and when hovering the mouse over the link, it shows the destination as the previous link that has been deleted.

This only appears to affect the html version of the email, so the plain text part is still correct.

Understandably, the problem isn't immediately noticeable as the link still looks correct, and it is only when clicking or hovering over the link that the discrepancy is evident.

I realise (now I am aware of the issue) this can be resolved by deleting the previous link first, then pasting the new link separately, but it would be helpful to know if there is a way to prevent this happening in the first place as it means having to remember that Thunderbird is quirky with swapping links.
