Thunderbird Support Forum

PC is an Apply Mac Book Pro running latest operating system software: Sonoma 14.4.1 ... after installing 14.4.1, Thunderbird slowed down in all facets: loading mail, opening selected mail, deleting mail, etc. Anyone else experiencing this issue, if so, were you able to resolve it and how? Thank you!

Anytime I attempt to send an email in the CCC ONE application, I get this error message from CCC ONE:

"Unable to perform selected action while the email application is open. Please close your email application and try again."

This error message persists whether I do have Thunderbird open or not. I also checked Task manager while I had Thunderbird closed and found no instance of it running. Is there any way that Thunderbird is running in the background? Or could it be if Thunderbird loads at start up that it's tricking CCC into thinking it's open all the time?

I contacted CCC ONE report and they advised me to attempt to change the name of a DLL file so a new one would be created to replace it. I tried that, the issue still persists. They also told me to try and uninstall and reinstall Thunderbird, which I did, and it still won't work.

Any ideas on how to fix this?

After importing events from the old ics calendar into the existing CalDav calendar. TB sent invitations out to all attendees, even for past meetings. How to avoid this?

I'm trying to migrate Thunderbird from my old PC/Windows 10 to my brand-new PC/Windows 10, following the step-by-step instructions on https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer. I followed those instructions to the letter (multiple times) but can't get it to work. Are there more recent (and perhaps more complete) instructions to be found elsewhere? Does anyone else have the same?

I have made a copy of my old TB profile folder on a backup stick (it is titled 'Thunderbird', and inside that folder is a folder titled 'Profiles' that contains a number of folders including the most recent profile that I am still using with my old PC. The difficulty is getting this backed up profile info installed on my new 'destination' computer.

Any suggestions would be greatly appreciated.

I'm trying to use Thunderbird to access my work emails directly. They use Outlook Office 365, which I can use the webmail version of just fine, but a year ago they upgraded to Oauth2 and MFA and for the life of me I cannot get any version of Thunderbord to work with it anymore. I can send an email, but I can access any email on the server. Weirder still is the error console message suggest the program thinks I cancelled my password entry;

"Loading failed for the <script> with source “chrome://global/content/netError.js”. neterror:128:4

NS_ERROR_ABORT: User canceled primary password entry"

This can't be this difficult. I need to setup a separate IMAP and SMTP server for accounts. I use SendGrid, so I need my IMAP to my server and SMTP using SendGrid's SMTP. However, it seems Thunderbird can't do this and only stores one password per account?

I hope there is a solution to this. With e-mail spam filters and such, if this isn't possible then I need to find another email solution. I've used Thunderbird for years and love it, but this might be what pushes me to something else, because I don't have a choice anymore.

Thanks for any help on this issue.

how can i stop thunderbird from interacting with windows defender anti virus scan? when ever i download or delete emails i get a few seconds of "not responding " and the whole computer is non responsive. i used to be able to turn off real time scan in security and it would work for a day and then windows would enable it again. now since the last upgrade windows isnt allowing me that option any more. solutions?

Thunderbird won't send an email because it thinks the email address I'm sending to has spam features. When I type the email address in the To bar it immediately puts an asterisk after the address. The email address is bzawacki@xxxxxxx.com. When I send the email it looks as though it sends then immediately an error message comes up that says the mail server responded with error code 43TH9mcn085202 and blocked the email because it has spam features. All I'm doing is sending an insurance estimate as an attachment to my car dealer. I've gone out to my ISP and added this address as a trusted sender but that didn't fix my issue.

I am the beneficiary (or victim, depending on how you view it) of Cox Communications turning all email services over to Yahoo. Both Cox & Yahoo store messages on an IMAP server.

As seems to be Yahoo's custom, they provided minimal documentation. Last night, in a 3+ hr call to tech support, for example, I noticed that my inbox had exactly 10,000 messages. (I know. It's not Inbox Zero -- I'm a bad, bad boy.) This seems suspicious, so I asked Yahoo's tech support agent about it. At first they said Yahoo puts no limits on messages and blamed Thunderbird for this. Then I showed them my employer's Gmail inbox with 35K messages and said this proves it's not Thunderbird. Then the agent said Yahoo has no limit. Then, apparently after getting feedback from their "support team," they said there's a limit of 10,000 messages per folder. So, even Yahoo's tech "support" seems almost clueless about such undocumented "features."

I know I need to trim the inbox, but I also need to keep lots of messages currently in it. So, the first thing I have to do is to move a large number of messages from the Inbox to another folder whose contents will be fixed.

To do this, I first created a folder to keep the original messages, "Cox Inbox."

Then I created a message filter with the following logic:

• Match all of the following: Date, is before, 4/7/24 (the day before Cox migrated my account)
• Move message to, Cox Inbox

But despite trying this repeatedly (I also tried "Match any of the following"), most messages stay in the Inbox and relatively few make it to the "Cox Inbox." I don't know how to troubleshoot this. Can you help?

Not being able to get the filter to work, I tried brute force. In my Inbox, I highlighted all the messages I wanted to move, pressed CMD-C (I'm using a Mac), went to the Cox Inbox, and pressed CMD-V. But it seemed nothing happened. Again, I'm at a loss as to how to troubleshoot this. Please help.

In my left tool bar I have:

xxxx@cox.net pop server followed by about 40 folders. This was the Cox email that is no longer in use.

xxxx@gmail.com followed by folders

xxxx@cox.net this is the new imap cox.net using yahoo.

Is it possible to move the bottom cox.net to the top, followed by gmail, followed by the no longer in use pop cox.net?

Thanks

I have created a label library on different computers, but if I add a label other than the standard one on one of the computers, it does not appear on the others. I mean like number 6 Techniczne.

I have had good success with Thunderbird until this morning when, posting a second email with photos to my wife, I got the message that the server connection timed out. I called my email internet provider locally, suggested to uninstall and reinstall, to check configuration. None of that worked. I modified one setting, the name of the outgoing server, when I checked with the protocols provided by the email/internet local provider. That also didn't help. I'm at a loss.

Thanks if you can help.

A: All these problems started after the new email version was installed, in-other-words, when the old version was updated! B: All of my email that was in my account / on my computer seem to be be there as far as I can tell. I can get to them, I can open them and see their contents. C: All is ok up til this point...as mentioned above and no new email has arrived. D: Now, as soon as I click on the "Get Messages" (Icon, looks like a cloud) in the upper left corner, is when I the Yahoo page of some sort pops on the screen, that's it. No mail arrives and I'm stuck with the Yahoo page covering most of the screen. E: I can click click around and try entering my email address but when I click on F: I see that images can be attached, and hope it works. My screen are,1920 x 1080, so I'll try and reduce the size of the images when I attach them. G: (Image A) After I inter my email address the red wording pops up.

    (Image B)   My email address pops up. That's it. Sometimes, If I click around a second page will pop up and

it becomes vicious circle and normally going back to the first page. (Note: A image) [about:blank] ??? Other pages have an address??? H. In these 4 days I have changed, added, deleted, used my Mozilla Reset Key, and this morning, per Mozilla's - Thunderbird's request, created another Reset key. Still no email. I do believe If this Yahoo thing was gone my email might start, just a guess now. H. Will all of the email that has not arrive still be available?? I. Almost forgot to mention. I receive and send my email through Thunderbird, and Yahoo & AT&T. Thanks, Bob Miller And, "Yes" please email or call, anytime day or night. I am getting a few emails on my phone. miller.485@sbcglobal.net

P.S...."Somethings Wrong"  :-( Again, thanks for your help!

bold text All of a sudden today Saturday the 11th Thunderbird stopped sending email on COX but it can receive them. It was working fine then all of a sudden the sending of email stopped. At first I thought that is was Cox being down again, (I've had connection problems this week). But while I was trying to figure it out I received a number of emails. I tried sending a test email to myself usually they go right away but it did not go.

I called Cox. They tech connected to my computer, made some checks, (updated Thunderbird) and after about 20 minutes it started to send messages. 10 minutes later it stopped working AGAIN. This started a four hour telephone marathon with just about every level of service that Cox has. I ended up with Complete Care and while I was on the phone with him and he was connected to my computer the service tech from Cox who was here to check my signal and modem showed up. He tried to look at the problem and could not figure it out. Note I can send and receive mail from the COX email website but and only receive email in Thunderbird.

Cox tells me it is a Mozilla or Thunderbird problem I'm telling them it is not that it is a Cox problem because the server is SENDING me email to Thunderbird but the Cox INCOMING mail server it not connecting to Thunderbird to receive emails. They claim that because I can send and receive on the web page but can not send with Thunderbird. I'm telling them it is a Cox problem.

Anyone else have this issue? Anyone have a solution? I'm shutdown here with over a 25 year history of emails sitting in Thunderbird.
