New Computer--4 days old Have downloaded Thunderbird (twice, the latest version from Moz website) Thunderbird crashes whenever I leave the computer long enough for it to go into sleep mode Crash reason: EXCEPTION_ACCESS_VIOLATION_READ Troubleshooting gives no answers Now running in Troubleshoot Mode having disabled add ons (none, I believe) Not much running on new computer yet--Avast, DuckDuckGo [I had a browser crash & needed to reload it on day 2 of machine's life (DuckDuck)...which might mean it is a machine issue rather than Thunderbird?...] Help! bp-4f000aa4-9396-4686-9338-49b190250203

I have just done something that appears to have erased all my local folders in Thunderbird. Is there any way to retrieve them? I saw a few answers that I didn't understand. This is really devastating, so I hope I can get them back!

I know my outgoing and incoming mail servers, but when I configure the corresponding servers in Thunderbird, I encounter issues where emails cannot be sent. Receiving emails is not a problem.

I am using Thunderbird version 128.7.Oesr on an iMac running Sequoia 15.3. When trying to update a contact's information I'm finding some contacts allow for Edit Mode and other contacts do not even display the Edit button as an option. I've tried Troubleshooting mode, but have the same issue. Any advice would be much appreciated. Thanks, Ron

I suddenly cannot receive new messages, for the last 5 days I didn't change anything (in fact was out of town) but now I get an Error that says "Login to account ________ failed. Login to server mail.nctvocom with username ________ failed."

I'm using the latest version of Thunderbird on my MacBook Pro laptop computer. When I compose a new email, I can no longer Select All the email addresses from Contacts.

I was able to Select all the email addresses from the selected address book and then either click To or Bcc. The selected addresses would then go in the To or Bcc fields. It does not do this.

Any suggestions? Thank you.

I can send a single email to the several hundred email addresses in one of my Google Workspace labels with no problem using the online Gmail web interface. But when I try to send an identical email to the identical label members through the Google Workspace account in Thunderbird 128, it says there are too many recipients in the To: line. Is this limitation being imposed by Thunderbird itself or is it imposed by Google on messages sent from Thunderbird? Google Workspace chat AI bot says it's likely Thunderbird, but is it?

I am trying to send a message with lots of MIME attachments from Thunderbird and I get this error message: "Number of MIME parts exceeds maximum permitted". Unhelpfully it does not say what the maximum is and I cannot find this information in Support. Anyone know what the maximum number of MIME attachments to an email is? Thanks in advance

Hello,

I am using Thunderbird on a Huawei P30 Android with EMUI 12.

Emails sent from my mobile are not being copied to the "Sent" folder, neither on the smartphone nor on the server. As a result, I cannot find them on my phone or on my PC running Linux Ubuntu 24.04.

Did I forget to configure something in the app on my smartphone?

Thank you.

Hello, I'm using Thunderbird (128.7.0esr (64-bit) on Linux (Ubuntu 22.04) for many years now and this is first real problem I encountered. Veeam is a backup solution which is writing emails where the first headers are written in UTF-8 and the body in UTF-16. The attachment is written in UTF-8. The body is a summary written in UTF-16 When I open the mail the body is shown in Chinese characters. The attachment is normal and readable. Outlook has no problems reading this email and though it is possible to change Veeam to write everything in UTF-8 the system admin who is using outlook refuses to change it. Is this a known problem or do I have set some settings wrong ?

An old email with a similar subject line is always first in the list.

Maybe the time zone is incorrect according to RFC2822? But this is not a reason to make the letter top and a potential way to abuse attention.
