Today in two of my accounts I get error message "Unable to open the summary file for Inbox on imapML. Perhaps there was an error on disk, or the full path is too long." Two other accounts work fine so no error on disk, and full path hasn't changed.

Hi-

I had this working then it magically stopped about a year ago and I can't get it back. When I try to open a pdf I get "...could not be opened, because an unknown error occurred. Try saving to disk first and then opening the file."

I have gone into settings and re-selected adobe acrobat and restarted but still can't open.

I am on a mac.

Thanks for your help! Crazy frustrating and time wasting issue.

I saw where there was a same problem liste a couple of months ago but the solution did nto work. As of this morning I can no longer send with my CompuServe Account. There was no change in my settings, and I have had the account in place with Thunderbird for years. I get an error to enter my password again, I do, then no luck. It asks again. When I cancel, I get an alert, sending of the message failed, Unable to authenticate Outgoing Server (SMTP), please check the password and verify the "Authentication method" in "Account Settings|Outgoing Server (SMTP)

I tried change the password authentication from normal to OAuth2. No luck.

No problem with downloading messages; they all come through.

I saved the message to be sent in my Draft Folder and then when going to the web version of CompuServe (really AOL and really Yahoo), my message is saved in the Draft Folder and I can then send it.

Thank you in advance.

When clicking any hot link in an email, whether FB or a web retailer email, etc. this message pops up: "This file does not have an app associated with it for performing this action. Please install an app, or if one is already installed, create and association in the Default App Settings page."

At a loss for a solution here. Can someone please help. Thanks.

When someone sends me a msg, it displays along with the HTTP equivalent? Trying to figure out what setting is out of Wack such that I ses the HTTPS display of the message? Thanks

When I use Mail Merge to generate emails for many recipients, they are put in the "Outbox", but Thunderbird will only send 10 emails at a time. After 10 emails, I have to close the program and start it again to get the next 10 sent. So to send 100 emails, the program has to be closed and started 10 times!

I have a problem with thunderbird. I can't fetch the certificate in my account settings, it seems it's not security approved. Normally when I type "fetch certificate" a window pops up asking me to confirm a security exception, but this function no longer works on thunderbird. Is there another way I can confirm the security exception?

I'm running Thunderbird 140.5.0esr (32-bit) on Windows 10 Pro Build 19045. After the last few updates the columns in the email listings are changing widths from what I've set them, this seems to happen after I close then reopen Thunderbird; which I'm having to do more often these days to resolve weird calendar malfunctions. For instance, the data column would appear so narrow that only the month/day show with "..." at the end, when I know I've looked at this yesterday with the full view of the date and time showing. I've reviewed my options and I've set them individually, set them globally and it makes no difference. Of course I've rebooted, etc. I have over a hundred local folders and they all change differently, of course some look the same but others don't. Most have the same column headings selected but it doesn't seem to matter. Some have the "Correspondents" column selected but many don't.

This is very irritating and I'd like to know why Thunderbird is doing this, and more importantly, how can I prevent this behavior in the future. Thanks,

Hello,

I've used Thunderbird for my e-mail for approximately 15 years, and now I can't currently send e-mail. I've gone through all the troubleshooting steps and also had Geek Squad attempt to fix it, but I'm still unable to send e-mail (I can receive them).

I've changed my password multiple times, reinstalled a fresh copy of Thunderbird on my Windows 11 laptop, restored the default settings for the outgoing server to align with what Verizon has specified, and nothing resolves the problem.

I keep getting the message: " Sending of the message failed. An error occurred while sending mail. The mail server responded: Email rejected. Please verify that your email address is correct in your account settings and try again."

Please let me know what the next step is so that I can use Thunderbird to send and receive my e-mails, like I have in the past.

Just opened TB. There were 8 or 10 emails. Went to another app for a few seconds. Went back to TB. Emails were gone. Have NO idea what happened. Know of any way to get them back or where they went?

How in the world is Thunderbird 5 revisions behind in the flatpak repo, i.e. 140? But current version is 145? Windows version is 145, but flakpak is only 140? REALLY FRUSTRATING when you are migrating from Windows to Linux and Thunderbird is way out of date! No wonder people don't like migrating to Linux. You make it truly painful! Documentation/website for Thunderbird states that flatpak always installs latest version? RIGHT, what a load of BS.

Hello, i am currently woking on an issue inside of the latest version of thunderbird. We have the data file for thunderbird located on the desktop. It shows as 37gb of data. however when we try to open the data file from inside of thunderbird. We cannot see any of the information from the folder. If i go all the was into the data file directory and select sub folders, they will open inside of thunderbird and show correct data. however, when i set thunderbird to open the entire directory with its sub folders, the application does not display any of the sub folders or information from inside the folders. We have attempted to go into properties and repair the file from inside thunderbird. It shows as 0kb file inside of thunderbird. it shows as a 37gb folder on the desktop. Once again to clarify, i can access specific directories inside the data folder but not the data folder as a whole. Any support or suggestions would be greatly appreciated. Thanks You

After many years of using Thunderbird with an AOL account I changed my password in AOL to increase the security. So I had to install the AOL account again in Thunderbird. I created an app password in AOL and put it in Thunderbird. Everythin fine so far. AOL login window opens automatically. But after login to AOL the message "somthing went wrong" and "try on anther device" pops up. I tried it on several PC's - no way. Other mail clients like Mailspring oder Mailbird did work with the AOL account. What is the problem?

With thunderbird version 140.4.0esr (64-Bit) on Linux functions to print e-mails or pdf documents is no longer working. When trying to print an email or a pdf document thunderbird starts looping and you need to stop thunderbird from outside with a kill command.
