I find it to be a big oversight that the project is so mature but still doesn't have RTL support out of the box. The (unofficial) add-ons that supply this functionality are yet to be updated to be compatible with version 115. Isn't it time to make this part of the base program?

I've been a faithful Thunderbird user since the beginning - and continue to use Thunderbird with our company's Microsoft365 deployment

until Monday of this week -- when suddenly I find that my credentials are being refused.

The symptoms

• XXX: Connected to outlook.office365.com
• nothing in the activity viewer
• no email coming in

I've read and tried all the fixes proposed in the article at https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202 (restarting thunderbird after each step, naturally)

• have authorized Thunderbird to our Microsoft365 tenant
• created and tried registering with a new thunderbird profile
• have set my security settings to 'accept all cookies'
• have used the config editor to remove 'oauth2.issuer' and 'oauth2.scope' values
• I've checked that my account in Microsoft365 has IMAP and Authenticated SMTP enabled

So, since Monday, I've been living in hell, trying to pretend that the Microsoft Outlook app for macOS is useable, but it's practically debilitating to be forced to use that piece of software.

Can somebody please point me to another possible set of steps that I can use to try and diagnose this?

I absolutely hate myself for having to ask for help on this, but I'm at my wit's end...

Hi. It looks like there was a Thunderbird update and my inbox and sent boxes are completely empty. It says I'm getting emails (I did a test), but I can't see them anywhere.

for about a month now I have not been able to download mail on Thunderbird for the Gmail account Configuration: imap.gmail.com port 993 SSL/TLS Oauth2 I have double authentication, the confirmation request appears on my smartphone, I confirm, insert the password on Thunderbird, accept the conditions and get the error. I also tried to change the password (on Firefox and Chrome I log in regularly, on smartphones too), with Thunderbird 102.13.0 32 bit on windows 11 no.... Below are the screenshots

Hi; I noticed today that many years of archived emails have disappeared in all but 1 account(yahoo). The only years still there are 2020 and 2021 in 5 different accounts. 5 yrs in 1 account and complete 24 yrs in yahoo account. These accounts archives that disappeared are not stored on the mail server but locally. What has happened??? Can I get them back? How do I stop this from happening?

I'm not able to tag email when email is being viewed since new update.

If I want to tag the email, I have to close the email and tag it in the list of all my emails. Also when an email is open, you can't see that it's been tagged (if it has been).

Is this your error and why doesn't it accept my password nor does it accept a changed password? Enter your password for jas91minq@hotmail.com on imap-mail.outlook.com You can email me although I won't get it via Firefox but I can get it on iphone withEdison

Since the last update my Thunderbird keeps frizzing up and I have to use Task manger to close it and then open it again. This happens all the time! I need this email program to work right.

Thanks Bob Williams

I checked everything also by the provider the settings are OK as far as I can see. Sending mail from my G-mail account is no problem! Hoping you can help me regards P.Rensel

Hello, on my bussiness mail on thunderbird mails that i read are all deleted. I didn't do anything to do them, is there any way to bring them back? There are very important messages in them that i really need

I send a message with large attachments and get the error it exceeds the Secure Attachment Policy. What is that? How do I change it? I used config to edit the config file and increase the size allowed and changed the warning thing to false but nothing works. This just started with the most recent upgrade. 2nd Question: How revert to the older version of Thunderbird? Thanks

I always thought that some of the best advice is "If it ain't broke, don't fix it." This concerns aspects of 102.13.0 that worked fine, but are glitchy in 115.0.1.

I use Thunderbird to archive from Hotmail (Outlook), AOL, AT&T's Currently (a Yahoo front), and GMail. I am also having to abandon Hotmail (Outlook) because of the characteristic haphazard programming that Microsoft practices, so I have been moving folder contents, sometimes many messages, at a time.

I see that the visual indicators in 115.0.1 is glitchy. I just selected a brace of about 817 emails in a Hotmail folder to be moved to the locally stored Thunderbird folder. After having higlighted the range, when I drag to the Thunderbird folder, only one file shows as being moved, but it stays visible in the source window *and* displays a weak-flash around that one file in the source window.

If I look elsewhere, I can see indication that the files are being moved, but the quirky flashing really looks like there is some error.

When the files to be moved finally all disappear from the source window, I then get a notification that slides in from the top right, saying, "The operation on XXXX failed because there was" and this is the *next* problem, because (1) the window is too small to display the complete message, (2) it slides away much too quickly to be read at a normal pace, (3) there is no way to retrieve and read the complete message, and (4) the movement of emails HAS, in fact, been completed.

Sometimes when I delete a group of emails from my inbox it deleted the entire inbox. It has happened twice now. When it did it yesterday I had 8 emails selected for deletion. When I hit delete it deleted all 2200 emails in the box. When it was deleting them I confirmed that only 8 were selected by looking at the number of selected in the lower right corner of the screen. Worse, when I click undo the delete it does not restore the 2200 deleted but only the 8 that I had selected for deletion. This is a serious bug and has resulted in loss of all my emails over the few years.

I've been a Thunderbird user for many years and have always been impressed with its ability to send most spam messages to the junk folder. However, the new version of Thunderbird, while visually appealing, no longer filters spam and I have to send the messages to junk manually. What is wrong with the new version?

Hello volunteers -- I downloaded Thunderbird to a newer iMac. The Input messages and folders from my laptop appeared fine, but the addresses look like they are from Contacts rather than the laptop Address Book, i.e., names, phone numbers and postal addresses, but not email addresses. The first image (screenshot from an Apple laptop) is what I want; the second is what I got on the iMac. Is someone able to help me with this? Thanks very much, Susan
