Thunderbird Support Forum

Using Thunderbird version 115.11.0 (64-bit) with Windows 7 OS and THREADING TURNED OFF.

When I receive a second reply to an email I've sent via one of my email service providers that uses an outlook365 server, my thunderbird view hides it beneath the first reply unless I manually intervene by clicking on the "greater than" sign associated with the first reply. When I do click on the first reply the greater than sign spins clockwise 90 degrees and the second reply appears below the first as if it were in a subdirectory.

The above behaviour is very inconvenient because I am prone to missing the second reply and have trouble anticipating its existence. Admittedly the unread second reply does change the first reply's text property to "bold" but I much prefer to see the new message without having to manually click on everything bold to check.

Another email service provider I use also has an Outlook365 server but second replies to emails are not hidden in its associated thunderbird inbox?

Can anything be done in thunderbird to stop this "feature" or is it absolutely fixed by service providers?

We had a storm and now email doesn't work. We are a business and have to have email. I've went in and changed the Mozilla password and when go back to email it won't accept it. Emails aren't coming through. Can't sign in. What do I do?

I have over 35 email accounts, which I use Thunderbird to collect. Love Thunderbird for well over 2 decades!

I am wanting to have 2 of my email addresses to be downloaded before all the others. I have indeed successfully "moved" these 2 accounts to the top of my account list (Shift and mouse). However they are not downloaded in the order of the account list.

How do I accomplish this? Is it possible?

I created a ticket, and it auto-responded to run this by the Volunteer Community. I really want this to be handled by support, but welcome anyone to give me a solid answer.

Right now I'm using 3 different email accounts on Thunderbird. All 3 of them are Office365 accounts. For some reason, 1 of the 3 accounts is prompted at least once a day, sometimes twice a day, to enter my password on the Office365 website popup that is used with the OAuth2 authentication process. It's very irritating, all 3 accounts are Microsoft Office business accounts. What would be the reason why it needs to authenticate daily? Is there no password manager to do this automatically once it's been entered once? Can I pick a different authentication method? What is the correct change to make so I don't have to keep typing in my password every day?

"Unable to write the email to the mailbox. Make sure the fle system allows you write privileges, and you have enough disk space to copy the mailbox."

After years of working fine, this message has started appearing whenever TB tries to retrieve messages. I've checked that there's enough space (there's many GB free). I've checked the authorisations of the email folders, they're all fine (Full Control in all cases). I found an answer in a forum suggesting that a rogue antivirus might be the problem, but I'm only using MS Defender.

In desperation I removed the entire Roaming/Thunderbird folder, uninstalled TB, reinstalled it (version 115.12.2), created a new profile for my email address (it's a Yahoo email address, and I can retrieve the emails directly through the Yahoo Mail website with no problems). But I'm still getting the same error message. TB tries to retrieve the messages, it says 'Retrieving message 1 of 105' for several minutes, then the error message popup, and nothing appears in the Inbox. (105 is all the incoming messages as of now since this started happening).

I'm completely stuck. Any suggestions?

I back up my TB profile every few months. I just went thru the Cox-Yahoo email conversion and I am getting emails. When I did my back up, I noticed in the properties it had one more folder and the files went from 1311 to 2585 files. Is something wrong? Do I need to compare and research what is causing this or just move on!

I would like to set up an email account with a pen name that I am using as an author. Is there a way to do that without giving my actual credentials? Thanks for your kind attention.

When I wanted to add a new subfolder to an existing folder, I think I used to right click on the folder under which I wanted to create a new subfolder. A menu would pop up with a line about adding a new subfolder. Now that option no longer appears. What happened, and how can I fix this, or how do I add a subfolder now?

Hello! We are a real dues-paying member, having made a number of donations over the years. We have been having trouble with emails received from Microsoft-based systems, with the HTML formatting of messages getting lost and the attachment of a winmail.dat file, which we can't open. We tried to use your Lookout add-on, but with all of the permissions that must be given in order to use that add-on, it will not pass our IT security folks. Is there any chance you will be able to improve Thunderbird to read those messages without having to use the add-on? We really hate Microsoft, and would prefer to stay on your team, but we will not be able to unless a solution can be found.

Thanks! Mark

Despite literally hours of frustrating -- now infuriating -- effort, my inbox won't show "from," which was removed by the most recent update. Is this problem fixable? If so, how? (If not, I'm damn well going to dump Thunderbird.)

In the past, I could click on an email address and drag it into a new subfolder I'd made (let's say for emails to a group about baking). Easy as pie!

Sorry for the bad pun.

Now, when I try to click and drag, it will NOT go into that subfolder. I looked in Help and there were answers about csv files, about a horizontal or vertical view, etc. None of that made sense to me.

So I'm wondering if it's still somehow an easy thing to do, to duplicate someone's email in one or more other folders. It seems like it should be! Thanks, Su

Hi There,

After installing the new thunderbird release 15.12.2, i started getting alot of duplicates. i was messing around in the thunderbird layout etc There was a report about a damaged mailbox, but not the inbox. i think i was behind on compacting. Then i realized most of inbox was gone !

i tried the repair suggested in Thunderbird properties on the message summary index file .msf when i first noticed problem, i made copies both inbox and .msf currently:

Inbox itself is ~2Gb, but  Inbox.msf file size is 0 

i have copy of the Inbox, but copy of Inbox.msf is gone...

i reinstalled the latest thunderbird. but didn't help.

I took the advice of @Toad-Hall and uninstalled the flatpak version of thunderbird, then installed the version available as an rpm via dnf/yum and that worked. Life is good.

i'm running windows on a bootcamped macbook pro, windows 10 home. did i install correct version ? any other ideas ?

i have used thunderbird for many years and appreciate you'all for keeping it going !

thanks, Kathy

At our clinic when we cannot answer client calls it goes to voicemail. The voicemail the should be sent to our email and transcribed, however it hasn’t been. It leaves us with the only option to play voicemails aloud while clients are going in and out of the lobby, which we find unprofessional. Please help us fix this!

I don't know my password to open my email, how do I find it? I have had my email account for years never needed to sign in and now I'm out, I need help I have a lot of important messages waiting.

I seem to have lost the search bar that allowed me to find certain emails in specific folders. I am now left with the one that searches all my email folders. Why? How do I get it back?

I just noticed (after 7 yrs) I have Thunderbird(beta) 32 bit on my laptop windows 10 (64 bit machine) and Thunderbird 64 bit on my desk top Windows 10 (64 bit machine). How do I get the 64 bit Thunderbird on the laptop without loosing all my settings to login to my 4 email accounts?

In my inbox I see a couple of emails that (once opened, or even seeing preview) are not associated correctly to the original email sent or received. It's quite odd as it happened only a couple of times, but even after updating, rebooting and moving these messages, they are still showing the wrong addressee and content.

In the attached screenshot you can see the example. Looking forward to receiving your help. Best regards, Nuno
