I supply software that uses TB to send emails with an attachment (via MAPI - an invoice) I have a number of customers for whom this has stopped working. I tested all of these with the usual fixes. The app has full access to the folder containing the file. The app is set as administrator and is inside the firewall. I have set default mail app to TB. TB is set to check as default on startup. Yet windows keeps saying we need to define a default email client. One customer solved the problem by buying a new PC. I have another customer who has this problem on a new PC. There may be a common denominator in Microsoft Office which on loaded onto the PC's. If that is the problem then that is Microsoft denying access to TB? Has anyone had this problem and can suggest a fix I would be grateful.

My email sending defaults to send later, I have to close Thunderbird to get the emails to send now.

I have looked at extension and NONE are set

How do I get rid of the send later function

I am getting a number of messages "Sending of the message failed. SSL received a record with an incorrect Message Authentication Code. The configuration related to mail.tobymanning.co.uk must be corrected" when I send an email

We have been working with our server, Blue Mountain, for weeks now trying to correct ever shifting email issues: can't send or receive emails on laptop, can receive on phones but not send, then can't receive but can send. Then can't do either. Currently I haven't gotten an email on my phone since August 2, the last item there is a box that says "Correct credentials needed. Enter credentials for arimor@gorge.net." My husband's last email is a Newsbreak -- from a week or so ago. So we can't send or receive from laptop or phones, but in our last contact with Blue Mountain they said it must be a Thunderbird problem. I fervently hope it is because then our problems might be solved. Can you help?

Within last 2 to 3 weeks I noticed that when I click Get Messages the momentary line of text at bottom-left typically says "there are no new messages", or the "number of messages" about to be downloaded. (This is not the notification window at lower right.) Recently the number of messages actually received is not always correct. For instance, this morning the message was clearly "downloading messages 3 of 3", but only one appeared as a new, unread message in my inbox. This has occurred several times, sometimes qty is correct, sometimes not. My first question is whether this is a bug in Thunderbird, or something I need to pursue with my email provider? Second question: I am only requesting those for my account, but might the "missing messages" be downloaded for my wife's email?

If missing messages are for my wife how do I fix it so I only download mine? She doesn't have admin rights and I made no changes to our account settings. If missing messages are not hers then I am seriously concerned about this issue.

I have been receiving emails and newsletters from a number of companies for many years. Suddenly last December many stopped coming. I have been in touch with one in particular and I am still on their mailing list. I am unable to find anywhere I can check. And before anyone says check your Junk folder. I do that every day. It has gotten to the point where I will have to stop using Thunderbird. Where can I look to find out what is wrong.

Mircosoft has indicated that after Sept. 16 it is not possible to access my e mail account on outlook. They require a more modern/sophisticated method of authorization, login and password is not enough. What to do?

Text (in Swedish) from the e-mail that I received from outlook@communication.outlook.com:

Det här måste du göra

Om du får det här e-postmeddelandet använder du för närvarande en e-post- eller kalenderapp som ansluter till ditt Outlook.com-e-postkonto genom en mindre säker autentiseringsmetod. Du måste uppgradera din e-post- och kalenderapp från tredje part till en version som stöder moderna autentiseringsmetoder.

I have my email account set up on my phone (Android) and on Thunderbird. Both are set up the same way receiving emails via POP Mail server. Messages are left on the server until I delete them. Certain messages appear on my phone but never appear in Thunderbird. I do not have any spam filters set up on Thunderbird. Junk settings are set such that messages from people in my personal address book are not treated as junk, and yet they are also amongst those that do not appear. Junk messages, in any case, are not moved from my mail folder.

Furthermore if I try to forward the missing messages from my phone (where they appear) to myself again, they will still not appear in Thunderbird.

Why cannot I not see those (missing) messages?

I just got a new computer and I installed thunderbird so I can access my work email that I set up with thunderbird. I'm having trouble signing in to the business account I use for work.

Sync or import from 1 PC to another with different versions of Thunderbird. What version do I need? Does it work? Is there a way to backup the messages and addresses on an external disk to access later?
