Thunderbird-Hilfeforum

Since I updated to the last Thunderbird version, the messages in my inbox are deleted after one month if I don't "star" them. I don't think I changed any settings? Can somebody help me with this?

Seems after the latest update Thunderbird will not receive some emails. It has stopped receiving emails coming from some cell phones and some .com emails. Some cell phone emails work and others that previously did do not anymore. I do not understand the random situation. No settings have been changed nor is there any setting to correct this. I even reinstalled Thunderbird.

Any suggestions would be great. Thanks

I have a Fastmail and 2 Cox addresses on rolled back Thunderbird 102. The Fastmail is IMap and both Cox addresses are POP 3. Cox is transitioning to Yahoo Mail, but we have kept our Cox addresses. I'm getting Yahoo mail web mail and think I should change the existing settings on Thunderbird and not create new accounts, but want to make sure. I saw something about Thunderbird and Yahoo and want to make sure I do it right or should use the third party setting for desktop clients that Cox provided for the transition. For me, the transition has not gone smoothly and I'm pretty frustrated. I am not a techie and any help in getting mail to the 2 Cox addresses landing in Thunderbird and the Fastmail continuing as is would be greatly appreciated. Thank you.

I have a calendar event with multiple people set up. I want to add a person to the event and only send a new invite to the new person (and not send a second invite to the original invitees). Is this possible? thanks.

When I click on the arrow to acquire any emails from my isp it will often say downloading 3 emails or 5 emails or some number, but only one or two come in. I have to hit the arrow again to get more. Sometimes it will say downloading some number of emails, but NOTHING comes in. I don't remember this happening until about a month ago. Can you help?

I am in the middle of creating a new event. If I click on the "Invite Attendees" button an "Invite Attendees" dialog appears with an email address already loaded in the first line. In my instance, this email address isn't mine! It is an alias on our corporate Zimbra email system that hasn't been used for 15 years, but is nowhere in my Thunderbird v102.15.1 client. It also isn't in any of my Thunderbird accounts. Where can I define this?

After the latest update: Every time I send a message and have selected at recipient, the program searches for a cetificate, allthough encryption is swichted off. A box appears for each recipient for about a minute, unless I stop the search (see image). Essentially, the program acts, as if I had selected encryption. This was newer an issue before latest update.

After last 2 updates several emails were showing up as code. I think I have that stopped. But now 1 email combines with many with to & subject correct, but the from & preview is all the same email from Amazon from 2017.As time goes on, it takes over more emails. My phone email is fine, so this is strictly a Thunderbird issue again.I used sfc/scannow & it said it found problems & they were repaired. Now I see a few more emails look like this. I'm about ready to chuck Thunderbird & go back to Outlook. This has been going on for several weeks with the first issue, the combined emails just started today.

Quite often I find that Thunderbird is very slow to obtain a connection with my Outlook account. I can run my Outlook directly and everything is updated in about 20 seconds and at the same time it may take a couple of minutes up to a few minutes for Thunderbird to complete downloading. Additionally, many times during this lag in connecting, I receive a message that the password is incorrect, which is bogus; all I have to do is select "Retry" and the download process continues. I am using the latest version of Thunderbird "115.10.2 (64-bit)." This problem has been occurring on previous versions as well.

Hi I am having problems with Thunderbird, i’m not sure if it’s to do with a windows 11 update or something else. Thunderbird is not responding also at the start of the ‘not responding’ emails from one of my accounts disappeared and then gradually started to reappear but didn’t get up to date and now just not responding st all. I have tried various things to resolve this, uninstalling and reinstalling Thunderbird, doing this and opening my pc in safe mode, doing this and opening Thunderbird in safe mode. Deleting and reinstalling the latest windows 11 update, reinstalling the latest Thunderbird update. I don’t know what to try next? I read somewhere to delete your profile, after saving it, and getting a new profile but no idea how to do this. Any help appreciated.

Am using 115.10.1 Thunderbird on Windows 10. This email account inbox shows one unread message, but I can't find any unread message. Toggled message threads to see if a previous message was unread, but could not find any there either. Have both closed Thunderbird and restarted the computer, but it made no difference. It is bothersome, but my main concern is whether this is indicating some virus or other hack of my computer. This is just a home computer, not on a business network. Do have it on wi-fi. Is it just a matter of somehow resetting the unread message indicator or is it a sign of something more serious?

My email was converted from Cox to Yahoo by Yahoo on a system wide conversion on April 27th. In the transition I lost all the emails in my Thunderbird inbox from 4/12 back to the first of the year. I also lost everything in my draft folder.

Carbonite did a restore of the default file (that was dated 4/8) by couldn't get these back. Need to get everything that was in the inbox and draft file on 4/26 (or sometime prior) What can I do?

My Yahoo IMAP account in Thunderbird no longer has any email showing in the Sent folder. There's plenty of mail in Yahoo Sent mail in the browser, but it's not finding its way into Thunderbird. I tried the Repair option, but I just get a typical message that I often see for Yahoo:

"The current operation on 'Inbox' did not succeed. The mail server for account Yahoo responded: [SERVERBUG] UID FETCH Server error - Please try again later."

The Yahoo account shows Sent mail in my iPhone. The Thunderbird Sent folder was seeing messages as recently as last week, so this seems to be a new problem, and I don't know if it's something that I did wrong by mistake. Thanks for any help.

I am trying to do a mass mailing in Thunderbird to about 2015 libraries, with another one to come. I followed all the instructions carefully and generated all the messages and they went into my outbox, with a "send later" command. Then this morning I entered the command to empty the outbox. I immediately began getting an error message that I could only send 50 messages an hour. Feeling like the sorcerer's apprentice, I closed thunderbird, whcih stopped the bleeding. Now I have 1350 messages in the outbox which thunderbird did not try to send.

Fixing up this mess is going to be complicated, particularly with respect to the messages it did try and fail to send (about 750 of them.) But I could make some real progress if I could figure out how to send 50 of the unset messages at a time from the outbox. I have the first 50 out of the 1350 selected right now, but I can't figure out how to get them sent. HELP! Thanks in advance.

Good Day,

For the last few weeks, when using Thunderbird on Windows and writing a draft email, when clicking on the button to create a link, the draft email window freezes. This also happens if I use the menu bar Insert -> Links...

All other Thunderbird windows remain functioning, and I can effectively continue working, but the frozen draft window will remain on screen until closed through Task Manager.

This only happens when creating a Link, not inserting other objects, like an Image. This problem also does not happen with Thunderbird on Ubuntu.

I am running version 115.10.1.

Thanks in advance for any tips that could be of help.

Could not find anything in add-ons, settings, or about:config. There is a topic on this site https://support.mozilla.org/en-US/questions/1086884 but I am not able to follow it because there is no add-on or plugin to enable or I cannot find it.

Using Thunderbird on Linux I cannot delete any local folders, when I try to delete them I get more copies of the folders on reopening Thunderbird, after the system says it is "not responding" and I close it down. I have tried several times and now have multiple copies of the local folders I've tried to delete.
