Each time I try to send an email it tells me to select a certificate for Authentication. Each time I do this if I select any of the options and hit okay it does not work. But if I just hit cancel it sends the message I'm not sure how to get this error message to stop popping up or just go away all together or what the issue is in the first place.

Bonjour, depuis 2 jours mes 2 comptes de messagerie (jprobbe75@gmail.com et jprobbe92@gmail.com) sont bloqués par google. J'ai suivi votre tuto, mais en vain...pouvez vous vous connecter à mon mac pour analyser ce qui cloche? Merci JP ROBBE

Hi, I just got a new laptop and downloaded thunderbird. On the new computer, Thunderbird is slow to the point where I cannot use it. I've tried uninstalling it and reinstalling it, played with settings, and nothing seems to do the trick. I use a screen reader (JAWS) because I am blind but I've never had any issues with it before. It will work fine for a few minutes and then the slowness will begin. Any ideas how to resolve this?

I have problems sending multi-addressed emails. With a group of up to 10 addresses it works, but any more than that, the message is rejected. I sometimes need to send to around 130 addresses.

So, basically, I am using the latest version of Thunderbird and a Gmail account

I am having issues when it comes to the client staying connected to the server- big issues. Sometimes, it can take me up to an hour to download just two messages from the server. My internet is fine, and while browsing I don't have any issues- it's just with the email client

I thought about using the safe mode without the ad ons to see if that would help, but then I remembered that I didn't install any, so no, it probably wouldn't

Any ideas?. I'm not expecting lightning speeds, but 5/10 minutes would be a huge improvement on almost an hour wait.

Thanks

Hi, As of yesterday I am unable to send emails out. I keep getting this message below. I have gmail on same computer and that works fine. I am able to receive emails but can't send. Please help

I have recently set up and started using Thunderbird with all four of my email accounts. However, when composing an email in the "To" field, I find myself having to manually enter the full email addresses of recipients. Is there a way to access my address book from the imported emails to streamline this process?

I am a long time Thunderbird user on both Windows and now on Linux. My current Linux Mint system and Thunderbird are both current on updates. Thunderbird has been experiencing hang for several weeks (maybe more like a couple months) I have been living with it as it will recover if I wait a minute or so. Today when I started looking the issue I was more than a little disturbed to find the profile being used was located in mt home folder instead of on the server I had been using it on (I thought) for several years. Upon further examination it appears I have FOUR profile showing up and the one on the server has not been used in over a year. Why would my default profile not be where I expect it to be living??? I guessing I have a bunch personal folders data now scattered out across in at least three places and only one of them is getting backed up. NOT a very happy camper here today. . . See attached info: I didn't see anything in the log file, but then the hangs seem to recover when I wait them out.

Bonjour Depuis deux mois, tous les mails à destination de orange.fr et laposte.net reviennent non distribués Auriez-vous une explication ? Merci

Attachment shows screenshot of when I attempt to GET MESSAGES or SEND and email. this only started happening recently. My email service provider is comcast.net. Double checked the settings and also tried Thunderbird Troubleshoot Mode and nothing solves problem. How to fix?

New issue 2/10/24. TB (115.7.0) won't retrieve nor send emails thru Comcast. No settings or accts were changed. Went to an old restore point on Win 10, didn't help. Reset router, PC, uninstalled TB, reloaded TB, didn't help.

Reviewed past articles (most are old) tried some of those solutions, but no joy. Can't find an Xfinity (comcast) phone # to call their tech support, although I doubt if they're any help. Will blame it on TB no doubt.

Could really use some help here. Appreciate all you guys efforts!

Email that I am sending from Thunderbird is being rejected for no apparent reason by the recipient server. This is not due to an ISP or sending server security issue since, when I send exactly the same email from my ISP email web page (not Thunderbird) the email is received properly and accepted without error. So, the problem is most definitely with Thunderbird. The following is the header text from one of the rejection replies.

Do not reply that his is an issue with my ISP. It is not. It is purely a Thunderbird issue. Thanks for your time.
