Thunderbird Community Forum

I am a new user of Thunderbird. I have 4 email accounts. I am receiving multiple copies of emails both on my desktop and also on K-9 on my phone.

From reading the various entries on this support site I note this is a known problem. I have not found any posts that offer a solution.

Is there a solution? Do I need to run diagnostics to clarify my issue if so what diagnostics?

Thanks in advance.

Regards,

Mike Duffy

The last emails that I have received through you are dated September 24th. Why have none been received since please? I am receiving messages through other sources.

Hi. When I select any of local folders and press the right mouse button on it and then select Compact, nothing happens (any message or pop up). When I choose Imap folder and then select compact, everything works fine even if there is no need of compacting such folder there is a message that 0KB where freed. I choose both online and offline work to check, but nothing helps. I remember that on older versions compacting worked fine, but now I don't know where is the problem.

Thanks for any suggestions.

Dear Thunderbird team I am an avid user of TB (home desktop Windows PCs), but I have been resting on my laurels on v78 for a few years now. I know, shame on me. I would like to upgrade to a stable "modern" release (emphasis on "stable" please). Can you please advise if I should aspire to end up on 115 or 128, and how I might get there ? From reading some older blogs, there is advice that says.... first go to v91, then v102, then v115, and so. That seems a bit tortuous, but I am happy to do so if that is still the recommended approach.

Also, can you advise on how I manage my Profile through all this, do I need to do various exports/imports as I move through these different versions, etc.

Many Thanks

I have been using thunderbird for years and have 2 lightning calendars. These are stored locally in home/.thunderbird on Ubuntu - currently 24.01.1LTS, TB version just updated to 128.3.0esr. About a week ago I stopped being able to save calendar events, getting the message

An error occurred when writing to the calendar Home! Please see below for more information. Error code: MODIFICATION_FAILED. Description: Failed to write to calendar file file:///home/alasdair/.thunderbird/Home.ics: Could not create unique file in `/home/alasdair/.thunderbird' (NS_ERROR_FILE_ACCESS_DENIED)

I have uninstalled and reinstalled thunderbird to no effect. As I am the only user of the machine all prcesses run as me, the .thunderbird directory is owned by me and I have all permissions on it, as I have for all files in the directory. I can create and edit files there no problem. I have no idea how to d=fix this.

Hi, I've used thunderbird (now 128.3.0esr)/calendar for years on my NUC7 running linux (now 22.04.5 LTS) with no problems.

Within the last couple of days, however, I no longer seem to be able to "drag-and-drop" events or tasks from one day to another. I can use the mouse to select/delete/etc an event or tasks, but I can't seem to move them with the mouse -- I need to "edit" the events. Is this a known issue?

Any help appreciated -- I haven't been able to find anything about this with web searches.

Hello,

My client has a specific problem with Thunderbird, when he does something with mail for example moving it to a certain folder or deleting one, all emails disappear, then when he restart the app all emails show up again and that mail is not deleted/moved, I tried all of the suggestions in the attachment and problem sometimes disappear for 1-2hrs but always occurs again. Also Thunderbird generated 50+ Inbox folders by itself and it keeps making them all alone. I assume the problem is with some corrupted file but his thunderbird backup is about 50GB and he needs it all to be imported. It really drives me crazy.

Thank you in advance for your support, Hope we will solve this issue.

When I select multiple Inbox messages and right-click, there is no choice shown to delete all of them. Please see the uploaded images.

Thanks for your help, SweetTasha

Hi dear Mozilla-Community,

I have run into the issue that is described here: https://www.reddit.com/r/Thunderbird/comments/1fdwv49/what_is_thunderbird_doing_to_fix_this_outlook_in/ and solved here: https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202

Now, the issue for me is that i cannot select the OAuth2-password option on my outgoing server option because it simply is not there (see screenshot attached - it's in German but you will get the idea). Ingoing has been changed (automatically, I suppose) to OAuth2 and works just fine but the outgoing is broken.

I am on the newest Nebula 128...esr.

What can I do? Thanks a lot in advance!

Best regards, Konrad

I want to change settings in Thunderbird. Vivaldi 6.9.3447.51 (Stable channel) (64-bit) Revision 182bbf0e4fdf8cd7876d2b24819fde3147f9af97 OS Windows 10 Version 22H2 (Build 19045.4894)

I tried all the other options in drop down menus all over and they all come up. But clicking on settings does nothing. I even went into account settings and tried clicking on Thunderbird Settings and it does nothing there also. Can I reinstall over the existing program without losing anything to try and see if that helps and fixes the problem?

You can help by going back to the old format. The new format makes it more time-consuming to delete unneeded messages because the screen shows only a small number of messages at a time. Also, the smaller print is less user-friendly.

I tried changing the authentication method to OAUTH2 for my Outlook live mail account (POP). For that, I had to change the server name to office365.com. After restarting Thunderbird, I was able to download new messages but all the old messages already stored in Thunderbird disappeared, even though Thunderbird still shows the same old Local Directory as being used.

How do I change the authentication to OAUTH2 & get my old messages back?

If I delete & again create the Outlook live account, would it effect my old mails/filters ?

I have Thunderbird V115.15 in Windows 7. Last week it stopped working correctly. Now if it starts a download from gmail it fails saying the account is being accessed by something else (but it isn't). Then when it does try to download the messages I either get 3 to 10 copies of every message or every message is blank and from a blank sender. Right now it is reporting 542 messages being downloaded but all are empty with no from info and those messages are from a week ago.

I am pulling my hair out trying to get this back to functioning!

Thank you

TB latest version on MacOS latest version TB has option to mark messages as read if it determines them to be junk this does NOT work. It puts them in junk folder but keeps them as unread. very inconvenient... any solutions? thanks (attached)

When I opened Thunderbird today, I was greeted by a giant red message warning, "This is an unsupported version of Thunderbird!! Thunderbird monthly releases are not considered stable for general use." By following a provided link to the "latest stable version of Thunderbird," I found that was version 128.3.0esr.

I did not request an update. I did have Settings> General> Updates set to "Automatically install updates", so I suppose that is how I got this version. But how was I pushed to an unsupported version? Do I need to turn off automatic installs to be protected from this in the future?

Considering so many companies have adopted Microsoft Exchange/Outlook365 and their IT departments have locked out other communication protocols, are there any plans to address this in Thunderbird? Right now a lot of us can't use it because of this limitation. The only solutions so far appear to be Owl (for purchase) or DavMail (which requires a separate OpenJDK 8 installation). This is a fundamental need in Thunderbird rather than a third party add-on. I like the look of Thunderbird but, alas, am not able to use it.

Just today after installing latest Microsoft Windows 10 64-bit and upgrading Thunderbird to 128.2, when I launch Thunderbird, after 30 to 60 seconds, the app goes "busy" with the hourglass pointer, and I have to kill and restart. Each time it still freezes after one mouse click. It has been working on this computer for months without problems until now. The only thing that changed was an update to the latest Microsoft preview WIndows 10 64bit from "Windows Update" a couple days ago.

Is this my system only, or are others having this freeze problem? I have to kill Thunderbird after waiting several minutes with it still frozen.

I don't want to change to another email program.

I'm running thunderbird 128.3.0 ESR.

Are there keyboard shortcuts for creating headings and lists in HTML messages? You can walk through the menus

i.e. to create an h1 you can do:

1. select text with the keyboard; 2. press "alt+o, p, 1");

Would be nice to be able to:

1. select text with keyboard; 2. press control+alt+1 for h1, control+alt+2 for h2, etc.

Similarly for lists:

1. select text with the keyboard; 2. press "alt+control+l"; 3. press enter to get next item; 4. end with two presses of enter

Perhaps I missed this in the shortcuts help article?

Thanx for any info.

I have two iCloud mails in Thunderbird. The older one runs great. For the other new one - same settings - mails sent often appear totally blank in the sent folder. Going to the iCloud webmail, sent messages appear totally normal and mails are sent to destination without any problem. I tried everything, no avail. Also weird is I have two "sent" folders (for no clear reason). Both have this issue, not always. See screenshot of iCloud webmail.
