TB on PC: have noticed that my Calendar entries are not syncing up to Outlook.com. Entries added directly to Outlook.com sync okay to my PC TB. Contacts sync works fine both ways. I just upgraded to TB 128.12 but no change. I have checked all the TB Outlook server entries and they appear correct. Any ideas? Thanks.

Installation of the latest version during installation proceeds to the Finish option then goes to a Blank Screen with a Done at the bottom. The screen eventually after multiple clicks responds with "Thunderbird isn't responding".

I had been using the client with no problems with multiplr email accounts! Very frustrating after multiple attempts to identify the problem including the Trouble shoter having the same problem. Pease Help!!!!!!!!!!!!!!!

I am able to style tasks that are either completed/overdue/inprogress in userChrome.css . But so far I have not found a way to style canceled tasks.

Can someone help me ?

My AOL account has a single SPAM folder; however, in Thunderbird, the contents of that folder are divided between the folders Bulk and Trash. In synchronization settings, I don't see the "Spam" folder of AOL, and in fact when I subscribe or check Synchronization & Storage I don't see the simple "Spam" folder that is on AOL. I don't have ANY filters active in my AOL account in Thunderbird or directly on AOL. I've been using AOL since its inception, and Thunderbird for as long as I can remember as well. I'm not sure when the folder structure of my AOL account on Thundbird changed, probably a couple of years ago. It's not a huge thing, but I'm thinking that if not resolved it could turn into a huge thing.

I'd like to just have the single SPAM folder under my AOL account in Thunderbird just like it is on AOL. No need for it to be split into Bulk and Trash.

When I try to copy Thunderbird Profiles to my backup hard drive I get the following error message after a few minutes of writing the write stops and I get the following error: Cannot Read from the source file or disk" INBOX Type: File, Size: 315 MB. Date modified: 7/1/2025 6:54 PM If I press the Skip option the file backup proceeds normally with the remainder of the files in Profile. This started about 3 months ago -- previously all files in Profile backed up without a hitch. I am concerned that I am not getting a full backup. Please help!! Thank you Cliff Hill

I have 2 accounts in TB. In one of them Thunderbird has a folder named 'Junkmail' but on the server the folder is called 'Spam.' Thunderbird is not allowing me to rename the folder.

Any reason for the discrepancy?

New computer Ubuntu 24.04 Mate, older Ubuntu 22.04 Cinnamon. Following support transfer directions (open Thunderbird on new PC, close it, paste a copy of older .thunderbird from USB stick to .thunderbird on new, over write), when I open Thunderbird no accounts are shown only the create account screen. I find no update path for older Thunderbird. New PC came with 128 esr but I found a tarball of 115 .18.0, installed it and followed transfer directions with the same results. Seems like the esr version uses a profile ending with esr and ignores my older one. What are my options for transferring 20 years of significant messages? The hard way might be to identify the account specific files in my older profile and copy them into the new esr profile...

My tags stopped working, right click -> Tag no longer has the list of tags, although 'Manage Tags' shows my list of tags and 'New Tag' applies the tag to the selected message, but no tags appear on right click-> Tag list. I'm using Mac OS Version 15.5 and Thunderbird 139.0.2 and have rebooted and reinstalled Thunderbird to no effect. Thanks for any help you may have!

Cannot delete e-mails from inbox. Cannot move them to Trash. Will copy only a few into trash and not remove them from the inbox. Emptied trash, compacted inbox. Read your suggestions, not help. Using Windows 10, latest version, Thunderbird 139.0.2.

Certificate errors have been an ongoing, several-times-a-day frustration for me and other users, with different ISPs, since approximately June 25. Is anyone working on this bug? Because it clearly is a bug: Not only I but several other users have reported that Thunderbird worked fine until that date, then stopped working fine. What changed, and can it be put back the way it was, or can we receive some explicit instructions on how to fix it for ourselves? It's making Thunderbird borderline unusable. Every time I try to send a message, I have to confirm a security exception, then send it again. Several times a day, when I try to fetch messages, I have to confirm security exceptions. The confirmations never seem to stick. This is some BS.

Recently I noticed that in ALL of my Local Folders, I can no longer see any of the content. The headers show like normal, but I cannot open / read the content (presumably contained therein).

I have tried repairing individual folders, but nothing changes.

I have tried eliminating the .msf file, but nothing changes. A new .msf file is created, but the content is still not visible.

If I try and reply to a local email, the email is empty with the exception of the subject. Even though it shows the sender of the email (i.e. From), neither the email address nor the email content is copied into the reply.

I am slowly starting to worry that the individual files storing the email content are corrupt, but if I open the content file (i.e. non-.msf file) with Word, I get what I presume is the first / oldest email, but nothing more (even though the files are many MB large).

Is it significant that I have both "Local Folders" and "Local Folders.sbd" (as folders)? The content within them appears to be similar if not identical.

My email is stored on a NAS which I can access from any computer on my network (presuming I have set up Thunderbird appropriately); can this contribute to the issue?

Any other ideas which might lead to such an annoying issue? I really don't want to have lost all my emails for the past 20+ years.

Thanks in advance for any suggestions you make.

My desktop computer died, so I needed to copy all my data files from backup (which worked fine) and then install all the apps that I regularly run on my laptop. When I installed Thunderbird, I got the latest Release 139.02. It behaves very differently from what I think is called the "Classic View" that was running on my Desktop. I REALLY hate it, but can't figure out how to set the Thunderbird parameters to do that. My problems include:

-- Overview of Thunderbird "Views". I can't find any documentation that explains [a] the various viewing options that Thunderbird offers and [b] EXACTLY how to set them.

-- Release Notes. I haven't found any release notes to explain when/why a major change to view was done.

-- Periodically, even for same release, Thunderbird CHANGES my parameter settings. Most annoying is changing the General Message-List settings to "Show Only Display Names For People in My Address Book". I live in a retirement community where many husbands & wives share the same Email address. With this setting, Thunderbird shows the name associate with the first message I received from this Email address. So the heading doesn't show which person actually sent it (although I can make a good guess when Thunderbird is telling me it came from a dead person. [g]

Is there ANY way I can get Release 139.0.2 to display messages the way I've been seeing them for at least 10 years? I REALLY need help. (If I can't get Thunderbird to behave the way I want, seem like I might as well switch to reading/writing messages directly from Google Gmail web site. It's equally lacking in documentation, but I suppose that eventually I could figure it out.)

Thanks in advance for any help anybody can offer.GMail, I'd seriously consider switch to using Gmail directly without Thunderbird.)

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.

Having selected multiple messages, I'm trying to move them to a new sub-folder, however this option seems to have vanished! I've installed version 139.0.2 (64-bit).
