Forum zgromaźeństwa Thunderbird

I like to use specific font sizes, such as 11 or 12. Thunderbird appears to have only small, medium, and large font sizes. Does Thunderbird have specific font sizes?

I'm able to receive messages from Protonmail and Outlook after installing Thunderbird yesterday. Have not been able to send an outbound message to Protonmail. Error is "Send Message Error. Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) 127.0.0.1 timed out. Try Again.

I am able to send messages via Outlook. Outlook works no problem.

Any ideas on what to do for Protonmail to work?

This is a weird one. For a few months now, I've had to deal with either my email timestamps being wrong, or my calendar appointment times being wrong.

I'm on Linux. I can replicate this with both the Flatpak and my distribution package.

By default, my email timestamps are fine. But my calendar appointment times are out by around 17 hours (that is, Thunderbird says they are happening 17 hours earlier than they actually are). I compare this to my Fossify Calendar app on my phone, which I had to install recently so I had a single source of truth, which is always correct. (It uses davx5 OSE as a bridge)

So the appointments themselves...are fine. My other calendar app can display them okay.

If I want to get the appointment times to display correctly, the only way is to set an environment variable. Regardless of whether I set my timezone manually in Calendar settings or use the system timezone (which is correct!), nothing changes. This is the only way to get it to work:

``` TZ=Australia/AEST thunderbird ```

or:

``` TZ=Australia/AEST flatpak run org.mozilla.Thunderbird ```

Now, my appointment times are correct...but my email timestamps are off! They are 11 hours behind what they should be. Despite this being my actual timezone.

I don't know what else to do. Please, is there any way to get my timestamps consistent for both my email and my appointments?

Everything was working fine and then out of nowhere I try to send an e-mail and get "The message could not be sent because the connection to Outgoing server (SMTP) mail.rima.net timed out. Try again." Nothing had been changed, it just couldn't send and I've checked the settings that all appear to be OK, but I still cannot send e-mail. I'm receiving e-mail, but cannot send. What could be the issue?

Had this problem suddenly crop up since the update of one of my accounts not sending mail due to timeouts. I've not changed any passwords or settings since I had it working last. The message is the "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) [my workplace's SMTP server] timed out. Try again." one, and it's preventing me from sending any emails.

Specifics:

• It's one account (my work one: work runs an Outlook/Microsoft mail server).
• My personal account (gmail) sends fine. Both accounts recieve email fine too, so this is just one direction on one account.

Things I've tried:

• Switching my Firewall off makes no difference, so it's not a firewall problem
• It's not that the emails I'm trying to send are too large, one word test emails also don't send
• Extending the timeout time by 3x doesn't help

I also opened a second computer not yet running the latest version - the account worked fine. Then applied the upgrade and that broke things in exactly the same way as described above. So I'm pretty sure this is an issue caused by the upgrade in some way. Not sure if other people with Outlook servers are having the same problem or if there's any workaround available but would appreciate advice.

Yesterday morning, my Thunderbird app. was automatically updated..... since this occurred, I have not been able to compose a "New Message" after clicking on the "+ New Message" button. What should I do to regain the ability to compose "New Message"?

I try to access my messages from an outlook.com account with Thunderbird mac. I get the error message "the STAT command did not succeed". This happened suddenly today without changing any parameter. POP is enabled on this account. Moreover on another mac with Thunderbird everything is correct with the same account. Cookies are enabled I tried changing OAuth2 to normal and changing back. No sucess. What could I try next? Thanks.

Finding the folder an email is in, search just returns the emails. I have never seen the "Search Box" or the "View in Folder" button. How do I find the folder my search result lives in? Or for that matter, how do I find a subfolder that got moved by accident?

2~3日前にも同じ状態にになったのですが、ヘルプをいろいろ調べているうちに正常に表示されるようになりました、ヘルプを調べているうちにトラブルシューティングを押していたのかもしれません。…が、今日ももんだいなくしようしていましたが、一旦停止してい、次に作業を再開すると　 またメールフォルダーが消えてしまってました。今回はトラブルシューティングもしてみましたが、全くどうにもならないのですが、 何とかメールフォルダーを表示するほうほうがないでしょうか？…私は視力が非常に悪く視界もごくわずかしかないので、PCの画面も読むのに時間がかかり。返事にも思うように打ちづらくいろいろと教えていただくのに手間をおかけしますが何卒宜しくお願い致します。

Since upgrading to 140.0esr on Thunderbird, client freezes (Windows 11 indicates as "Thunderbird is not responding") for anything from a couple of seconds up to a minute or two whenever downloading emails in the background. This is very annoying, especially when trying to write a new message (or even while commenting here in the Ideas panel). My main account is on a Microsoft Exchange service, so I need to use the OWL add-in but the delays also seem to occur when accessing gmail. The other "feature" which seems to have changed is inbox defaulting to top then running through to end when sorted with most recent at bottom. I have now reversed to have most recent on top, which seems to have resolved, but this was also annoying. Attempted to resolve by clearing 1 GB from cache and archiving about 15K conversations - but interruptions not significantly improved. Until a few days ago Thunderbird seemed to run without any problems. Any suggestions?

I have just installed Thunderbird 139.0.2 and I am no longer getting event reminders. How can I restore the capability to have the event reminders displayed?

Fixed this event reminder problem: checking the settings box to "Show missed reminders for writable calendars" enabled Thunderbird 139.0.2 to open the reminder box to show the event before it is going to happen, as well as showing the event after it was going to happen. Never had to explicitly do this with previous versions of Thunderbird in the 20+ years I have been using the Thunderbird calendar.

Hello,

I have saved thousands of emails over the time in several local folders. Near 8Gb of emails with their attached documents. The local folder is in a Synology NAS in my local network.

I was trying to retrieve some of the emails saved in that local folders and found that I couldn't read any of the saved emails. I could see the list of the emails in all the folders but when clicked in one of the emails of the list, nothing was showed.

By saving all the files to the computer, I can read again all the emails. Never happened that it was a problem to read from the NAS. I could see a status bar in the bottom of the window showing the progress in the loading and after a short while, the email and the attached files were shown and loaded.

My local network seems to work ok and also the Synology.

So, my question is, has anything changed that blocks the reading of emails from the local network? Any idea on how to have the emails stored in the NAS?

Thanks

You are 'sorting' my email and I am missing important items. Please remove this sort option from gailw.DRShop@gmail.com and let me decide what is of primary importance and what should remain in date order in my inbox.

Thank you. Gail Warnaar Double Reed Shop

Greetings

After updating to 140 (release update channel), IMAP folders keep downloading all emails in a folder, even though the vast majority of them are already local. I get the message "Downloading message x of y in folder" and it goes folder by folder, some of these folders have a lot of mail so this can take ages.

I do have a lot of folders and emails, I have tried compacting and searched for weeks, and only very old and not exactly this issue, any ideas?

Dear Technical Support

I have problem in my email on thunderbird. my folder don't show email but in folder show data is 89mb. It's more than 5 folders have same this problem.

i repair it but Nothing happened.

How to Fixed it

Thank you

We keep getting a box with a message of put in a password to imap or something and we can't reply to emails. It works on my husband's laptop at his office but not the home computer or hhis laptop at home.

Bonjour,

Je rencontre un problème au niveau du password. En effet, sur un ordinateur thunderbird ne veut pas garder en mémoire le mot de passe que l'on renseigne en cochant la case gestionnaire alors qu'on arrive bien a s'y connecter quand on utilise nos outils internes.

Pouvez me dire si c'est un bug et comment le ressoudre svp ?
