Thunderbird Community Forum

Hello,

I’m encountering an issue after migrating my domain and professional email service.

My address was originally hosted by Cabanova and configured in Thunderbird. I recently transferred the domain and email hosting to OVH, which caused the old mail server configuration to stop working.

Here’s the current situation:

The account in Thunderbird is still using a POP server (ssl0.ovh.net – port 995), while OVH uses IMAP (port 993).

I cannot change the server type from POP to IMAP within the existing account settings.

When I try to add a new account, Thunderbird completely freezes after I click “Continue” and never gives me access to “Manual Configuration.”

I also cannot delete the existing account because it contains all my previous local emails that I need to keep.

At the moment, I’m able to send emails from this account via OVH, but I don’t receive any incoming messages.

What I’d like to do is simply update the server configuration to OVH’s IMAP settings, without losing my existing local messages or recreating the entire profile.

Could you please let me know if there’s a way to:

Force an existing POP account to switch to IMAP,

Or safely recreate the account as IMAP without losing local data and without Thunderbird freezing during setup?

Thank you in advance for your assistance,

We have poor eyesight, so in vertical display mode, we could really benefit from having grid lines (at least horizontally) to visually distinguish each message. We have read various solutions on the Internet, but none seems to work at least not in dark theme mode, which is the default for a great many people with vision impairments (or just plain tired eyes). Perhaps some solutions that once worked have been uprooted, so to speak, during the course of Thunderbird updates.

We are used to having grid lines in Outlook (desktop). We are currently exploring switching to Thunderbird, but it needs to support our vision needs. For us, this capability is fundamental, not optional.

We are comfortable making config entries, creating and working in userChrome.css, and the like. We would be grateful for any guidance in this regard.

Thank you kindly!

I am thinking of going back to Thunderbird as my e-mail program (I currently mostly use Apple Mail). I have several e-mail accounts. On my personal Gmail account, only a handful of sent messages are showing up in the sent mail folder. On another Gmail account and on my business Google Workspace account, I do not have that problem; as best I can tell, all the sent messages are there. I would appreciate help in fixing the problem on the main Gmail account that I use for personal matters.

Although they are selected "Return Receipt and Delivery Status Notification" don't work!

Delivery Status is up to receiver decision but "Return Receipt" should be returned at all time??

Thank you in advance fo any assistance.

PS: Version 140.3.1esr (32-bit)

URGENT Version 142 for Windows 64bit is unstable. It freezes over after almost any action with usual Windows "Not Responding" message. Recommendation to Mozilla: Pull back this release and roll back to 141

Howdy! So this problem started today, and I can't find a solution or reason it is happening. The only variable is that I grabbed my address books from my old pc and transferred them over to my new pc. I didn't change any settings, just put my address books on a thumbdrive and brought them over. I've been using my new pc for about a week now, and no issues until today.

Normally when I double click on an email, and it opens in a new window or tab, the status of the email in the email list automatically becomes "read", ie the little green dot becomes a little grey dot. For reasons beyond me, it has stopped working. The email stays in "not read" status, the green dot remains. It's driving me crazy, as only pc problems can. Anyone else having this issue? Oh, and yes I shut down and cold booted the pc and nothing changed. Thanks in advance!!

Hi I use a PC running Windows 10. I created a new email adress using Outlook. All is displayed correctly in Outlook.live (subir inbox, outbox, draft, archive, etc)

Now when I try to add the same account (email adress) in Thunderbird PC (last release), the system found well my data (IMAP, SMTP...), but is unable to display submenus. Only the Inbox appears. The setup is not complete and I have no error. But in Thunderbird I received a notification stating something about the authentication of that new email adress but I have no access to the full notification (when I clic on the notification it disappears).

I deleted this account (data and message) in Thunderbird, closed Thunderbird, and created it again, same result. Only the subdir inbox appears.

In Outlook.live this account works fine, I can send and receive emails.

In Thunderbird I can also send emails but I do not receive them while they are received in Outlook.live. So it seems that there an issue in Thunderbird And I have no opportunity to add the account manually.

Any suggestion to solve this issue ?

I'm running Thunderbird 140.3.1esr (64-bit) on Windows 11. Possibly because I was changing some settings, possibly because of a Thunderbird update, there are a couple of wonky things going on in my Folder Pane and elsewhere. Among them is the fact that one of my "Archives" folders now has a "Sent" icon instead of an "Archives" icon (see attached). Does anyone know how to fix this? I've tried the following: 1. Repairing the Thunderbird folder. 2. Restarting Thunderbird and my computer. 3. Installing the latest version of Thunderbird (without uninstalling though).

Hello, I speak french therefore sorry for my english ! I have since 3 days, the impossibility to send a mail. I always receive an error message like this :

L’envoi du message a échoué. Une erreur est survenue lors de l’envoi de l’e-mail : erreur du serveur SMTP. Le serveur a répondu : bluewin.ch mailout-004.p.bluenet.ch Swisscom AG sc774: Blocklisting in effect.

This have been caused as I wanted to send a message to a list of more of 100 personn and the system of my provider (Swisscom Bluewin) blocked me.

I contacted them explained the situation and the have deleted the blocking list and if I go on the email of the provider Swisscom I am free to send message without problem.

BUT in Mozilla Thunderbird i am still blocked with the above mentioned error message !

I have controlled all my SMTP info and they are correct, I have try to disabled the Bitdefender security but no way it remains blocked.

My question is, is this blocking list only remaining in Mozilla Thunderbird and for how long time or someone can help me to cancel this blocking list in Mozilla Thunderbird ?

Many thanks in advance for your help

While attempting to upgrade my Ubuntu Thunderbird client, I saw the attached screen. I'm concerned because of the unsophisticated style of the page, and the fact that it asks for my password, which makes me think "phishing". Can some trustworthy person confirm that this is a legitimate screen?

I have lost the possibility use Finnish dictionary for spell checking after Thunderbird upgrade to version 60.3.1. How could i revert to older version and prevent automatic updates?

I accepted update to Thunderbird version 60.0 but my Add-on has been disabled as non-compatible (Magyar (HU) Language Pack (Thunderbird) 52.0 and Français Language Pack (Thunderbird) 52.0.). When trying to find Add-on, same versions I have already are proposed and they are no more compatible with Thunderbird version 60.0 What can I do to have again spelling check available in French and Hungarian? Thanks for helping!

My husband and I have identical Thunderbird installations on identical Windows 7 machines, and for years we have been using 'QuoteAndComposeManager version 0.4.1. This allows us to set a 'pause' of 20 seconds between the time we click on Send and the email actually gets sent (it's amazing how many errors you can find in 20 seconds). This feature is still working fine on my machine, but on his it has been disabled with the message that it is incompatible with Thunderbird 60.3.0.

Two questions here: My update history shows that I am set for automatic updates, but the last one was to version 52.9.1 on 16 July 2018. This probably explains why I can still use the QandCManager, but why are we getting updates at different times?

More importantly, is there some other add-on that we can use to get this time-delay option? I have gone to the original developer's website but he does not seem to have a later version.

Many thanks.

I am finding it virtually impossible to find support for Mozilla products on support.mozilla.org simply because there is no obvious way to AND search terms rather than have the website OR them by default. When I get hundreds of results I want to refine them by adding more to my description, but when I do that I get even more results. If providing the option to select AND rather than OR is too difficult, at least have the search default to AND, which is in nearly every instance more helpful.

My Thunderbird version 52.9.1. First language = French Cannot upload DUTCH language package (as second language) because last version of complementary module appears to be corrupted. BA Brussels - Belgium 19-07-2018

I am using Ubuntu 18.04 with latest Thunderbird (52.8.0). Normaly (in older verions of Thunderbird, like the one in Ubuntu 17.10), it was possible to just install a language like described here: https://support.mozilla.org/en-US/kb/how-do-i-use-firefox-spell-checker in order to use the spell checker in a different language.

I clicked on "Sprachen -> Wörterbuch hinzufügen" and downloaded the german language packet. Now in "Add-ons-Verwaltung", there is "Deutsch (DE) Lanuage Pack", and it is activated. Unfortunately, if I right-click on any text, I still can not change to german. This did not change when restarting thunderbird. For "Wörterbuch" (Dictionary), the link for download is not present (while it is present for other languages, e.g. Afrikaans), but the link for "Sprachpacket herunterladen" keeps beeing there, even if I installed the language packet.

There are other users complaining in the comments section of the language pack: https://addons.mozilla.org/de/thunderbird/addon/deutsch-de-language-pack-thund/ (e.g. "Sprachpakete lassen sich nicht installieren. Anwendung ist völlig unbrauchbar!" means "Language packets can not be installed. Application is not usable at all." which may be an exaggeration.).

Is this still the right way to install a dictionary, or is the link to the dictionary maybe wrong? Can I install it somehow manually or by apt?

I came across a site "mozdev.org" that gives instructions as to how to download a file called "mailtweak-0.16.xpi" Firefox will not allow me to download it and I cannot find it in the list of Firefox add-ons.

Please advise

Before the Thunderbird 45.0 update came through, I used to use an ad-on called TT DeepDark. Since the update, I get an error message telling me that this add-on is not compatible with version 45.0. Because of a visual impairment, I depend on dark themes so that I can read more easily. I thought at first that it was something with that one individual add-on, so I searched for one to take its place. However, it appears that no theme add-on available through Mozilla is compatible with the latest version. Is there any kind of time frame for when this might be fixed?

I do know that things often depend on individual developer, but since every single theming add-on is currently nonfunctional, I know it isn’t something like dependent on an individual developer.

Is there any kind of workaround in the meantime? I really depend on that dark theme so that I can use Thunderbird more effectively.
