Thunderbird is set as my default email client on my desktop Windows 10 in the default apps and it's set in the Default Programs control panel but when I try to send a document on my desktop to mail recipient, a message comes up saying there is no email program associated to perform the requested action. It is set in Thunderbird as well as the default mail client. Cortana is no longer accessible on Windows 10 on my pc. Thunderbird is set as the email client in the registry settings, I have only a few Startup programs running on startup and cleared the cache in Thunderbird so I don't know what else to do to fix this?

I was moving stored emails between folders. After many moves, when moving a group, the move failed with message "TOO BIG" APPEND  ??. Since then, I have been unable to move or copy even single emails. How can this be cleared?

The employee who set up Thunderbird for us, has moved on to a different line of work & no longer with us. Her name is on all the emails and templates. How do I change these and how do I secure our emails from her use now that she moved on?

I edited & saved each and every Template earlier today. Then, when I went to check my work, nothing had changed.

Help me please.....and talk to me like I'm just beginning computers, because...I am.

I have had an ongoing problem with Thunderbird being unable to log into the various mail servers that I use. I've tried repeatedly to solve this problem and have been able to cure it in the past by clearing the cache, but it recurs over and over again. I cannot keep wasting my time like this. I'm an independent contractor and I need to be able to use my e-mail client consistently. I've got work to do! This morning, it's suddenly decided that it cannot log into any of the three services that I use.

Is there a lasting solution to this problem? If not, please tell me and I'll move on peacefully, but please don't keep me chasing my tail for something that cannot be fixed.

I have set my account to "Don't delete any messages", because I frequently want to reread a deleted message in my Trash folder. However, when I go into my Trash folder to search for a deleted message, I am finding that messages older than a certain date have disappeared, although I've done nothing to permanently delete them. For example, today everything older than May 3 is gone. What can I do to prevent this?

thanks, CW

Thunderbird 138/139, Windows 11 Pro 23H2. While composing a message, after a few lines the app freezes. Both the compose window and the main TB window freeze. Only opening the Windows Task manager allows me to close them. This did not happen with earlier versions.

If I save the message every few seconds while composing I can get most of the message back and continue after restarting TB. This behavior is the same in both the normal and troubleshooting TB modes. I can't even find a crash log to send to Mozilla.

Where shall I look next?

Thank you!

I previously successfully imported my configuration from Thunderbird desktop to my mobile app by scanning a QR code, and it worked perfectly. However, I recently had to reinstall my computer's operating system, which resulted in losing all my Thunderbird data. Now I'm trying to export the configuration from my mobile Thunderbird app back to the desktop version, but the export process generates a file with a .k9s extension. My question is: How can I import this .k9s file into my desktop Thunderbird installation? Any guidance on this would be greatly appreciated. Thank you!

Hello,

In looking at new messages the inbox, there is a button to send it to the Archive, and another to send it to the trash. Both buttons work as expected. However, the trash button is sending the message to both locations. Is that just the way it is? Or is there a way to only send it to trash? I've spent some time searching the settings and haven't found anything other then disabling the archive altogether. I also didn't find anyone complaining about this, so I suspect I've missed something.

Thanks!

I'm in the process of cleaning up Thunderbird e-mail before moving to a new computer. I started with 11,593 e-mails in my Inbox and 7,799 e-mails in my Sent folder. I'm now down to 7,634 in my Inbox and 4,965 in my Sent folder. I've allocated 2 weeks for this process and found that it's taking me about 3 hours per day to meet my daily goals. I'm finding that I'm spending at LEAST half the time responding to "Empty-Trash/Compact-folders" requests. There are times I can delete 50 e-mails at a time without getting a request. Other times I will try to delete ten e-mails and get the request. With the old version of Thunderbird I could literally delete hundreds of e-mails at a time. Can you help? Russ Bukwa Yardley, PA ps. I have intentionally given you specific numbers. Based on my software- and test-engineering experience, I speculate you need to create a stress test to solve this nagging problem.

I have two issues that are related to a buggy interaction between Thunderbird and Microsoft's email server.

Issue (1) When I send an email with my Outlook email address (from the Android app or from outlook.live.com, but not Thunderbird), my email address shows up as a jumbled mess in the sent folder on Thunderbird.

It appears to the effect of

IMCEAEX-_O=FIRST+20ORGANIZATION_OU=EXCHANGE+20ADMINISTRATIVE+20GROUP+XXXXXXXXXXXXXXXXX+29_CN=RECIPIENTS_CN=XXXXXXXXXXXXXXXX@sct-XX-XX-XXXX-X-msonline-outlook-6f06c.templateTenant

(I have masked some potentially sensitive information).

In the sent folder on my Outlook Android app, my email address looks normal. It also looks fine on a browser in outlook.live.com. However, it's in the sent folder on Thunderbird that my email address is a mess.

Issue (2) When my Outlook email address is involved, the sending and receiving email addresses in the "correspondent" field are swapped in Thunderbird.

There are a couple situations where this swap happens:

1. Sending an email with my Outlook email account (either through the Android app or outlook.live.com, but not Thunderbird). In my Outlook sent folder on Thunderbird, the "correspondent" field shows my jumbled email address and not the receiving address, such as bob@gmail.com. Likewise, In the inbox of the receiving email account (such as bob@gmail.com) on Thunderbird, the "correspondent" field shows bob@gmail.com and not my Outlook email address.
2. Sending an email with any other account in Thunderbird to my Outlook email address. In my Outlook inbox on Thunderbird, the "correspondent" field shows my Outlook email address (this time unjumbled) and not the sending email address. However, in the sent folder of the sending email account in Thunderbird, the "correspondent" field shows up correctly (i.e., my Outlook email address).

These two issues are perplexing and probably related. Thank you for any help!

My Thunderbird email works fine except when trying to send emails to someone with an Outlook account. The emails keep bouncing back undelivered.

Any ideas please

For a few days a banner persists on the lower left of the message window. It obscures content. ""Upgrade to Thunderbird Release"" I have checked twice to make sure there is no update available. Why does this annoying message persist after I run the update. I have rebooted the application multiple times. I do not want to click "Learn more" on the annoying banner promoting "Get monthly updates. with new features and improvements in the new Thunderbird Release" Is it malware? If the application is up to date why are you forcing me to "Learn more"? This is not a good user experience. My MacBook Air is up to date. Thunderbird release 128.11.1esr

I am currently using old outlook and am thinking of switching to Thunderbird for better mobile calender integration with my gmail account. I do not like IMAP as I prefer my data locally and it impacts performance. One aspect of outlook that I use constantly is reminders on emails, meaning a get a reminder on the date and time I set to look at an email that I sent or received in the past.

Can this be replicated in some way with Thunderbird?

I am not sure from which version this problem started but suddenly the images started showing at the very top of the email instead of being displayed inline with the content. In place of where the image should be it puts a text called image.png (screenshot 2)

I was on the esr channel when I noticed this issue and since then I have upgraded to Release 139 version and still the same issue is seen. Also images are not showing in the content.

I have been getting "Login to server pop.windstream.net with username everettbbailey failed." for the past several months. I have tried all the recommendations and correct settings for a pop server. Thanks.

Hello, we are facing an issue like unable view the emails. Resulting in blankpages.

Same issue happened last month also.

Current version - 139.0.2 and the we are using UNC path.

Any advice would be helpful!

Edit : currently we have downgraded to the thunderbird version 138.0.2 and we are able to view the emails.

We are trying to create an out-of-office response email and have found an issue. When creating the filter to respond with, the "Reply with template" option under "Perform these actions" is missing. We have checked the usual reasons why, but we cannot find what the problem is. We are using an Imap account. We have the 139.0.2 version of thunderbird, and we have set up the template necessary for the response without any issues. What could be the solution?
