Thunderbird Support Forum

Hello.

I read that thunderbird works with Microsoft 365 and modern authentication. I tested with Microsoft 365 accounts and it worked fine. The problems come with an accounting of Microsoft 365 operated by 21vianet service.

I configured according to https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202 with the IMAP and SMTP settings from https://support.microsoft.com/en-us/office/settings-for-pop-and-imap-access-for-microsoft-365-operated-by-21vianet-ca51235d-afc5-4d7d-843c-3616a37d5771

It complaints "The IMAP server partner.outlook.cn does not support the selected authentication method. Please change the 'Authentication method' in the 'Account Settings | Server settings.'"

In SMTP settings there is no option to configure OAuth2

After updating to the latest Thunderbird I checked my emails and closed the program - but not from the inbox. Now, T'bird insists on opening into that same screen and there is no link to to show my inbox. I have removed and re-installed T'bird with no result. I have tried approximately 15 'sure' fixes from the internet and Mozilla but without success. Finally I read that the new version will open the screen which you were last using at shutdown, but there is no link to open the inbox. There is no link to the inbox on the left side of screen nor a down caret on the right hand side of screen. I have no folders showing, such as "Inbox", "Drafts", "Sent" or 'Local Folder'. I have referred to the Mozilla list of shortcuts without success. My inbox is not empty F5 and Shift + F5 do nothing. The email address for my PC is: albanv@netspace.net.au How can I show my inbox?

Greetings once again: It's been well over a week now and still not able to download any e-mails from anyone. I've changed my password as you requested me to do and if I send out e-mails, they seem to go out just fine, but STILL no e-mails coming into my account. WHY IS THAT? Please let me know if there's anything else I need to do, to be able to receive my e-mails. Thanks again. Dave Beard [removed personal address from public]

Thunderbird 115.11.1 (64-bit)

Hello, I am using : 115.11.1 (64-bit) The last mail I have received was on 14/06. I have check the POP mail server, I have tried to open at the same time my mail box on the yahoo platform and on Thunderbird. I haven't changed anything and do not understand why suddenly i cannot see my new mails. I can send mails without issue though. Can someone help ? Thank you Sand

I have been using Thunderbird a long time and I have emails going back about twenty years. This means that the built in import/export feature is hopeless. So I copied the entire Thunderbird folder to the new computer. I was able to transfer thousands of emails, but when I looked more closely I saw that my new Thunderbird only went back about 2 years. I would be very grateful if someone could tell a way to make it include the missing older emails.

Hi

uBlock Origin for Thunderbird doesn't block Newsletter ads (blocked since install 0% ===> since months)

How-To fix and troubleshoot? Re-Install of add-on already done

Thanks

All of the sudden my subfolders under Sent disappeared and even the Sent folder disappeared. Plus TB keeps asking me for my password which is a long series of letters, ie. security key. Please help. There was very important info in those folders and I'm feeling kind of desparate. I uninstalled TB and reinstalled. Not fixed at all. Thank you.

While managing my Thunderbird Inbox, I inadvertantly transferred a chunk of Inbox messages received from my MS Office365 Outlook account into the trash. I went into Outlook on the WebApp and discovered that all of the inadvertantly deleted emails were found under recover deleted emails. So within Outlook I recovered all mails into the Inbox. So far, so good.

Now I have all the mails listed in the Inbox on Outlook. But when I open Thunderbird again, the recovered mails do not show up. It seems that Thunderbird does not fully synchronize the folder and the recovered emails are not downloaded. Instead, all mails are once again removed from the Outlook Inbox. The previously recovered mails disappear again from the inbox of OWA and I have to recover them all again.

I have already tried several fixes. Within Outlook, I created a new folder and moved the recovered Inbox mails to that folder. This was done in the hope that this folder will then sync properly with Thunderbird. Unfortunately no. The folder does not sync and as soon as Thunderbird is closed again, all mails are deleted again from the new folder on OWA.

I also deleted the Outlook account (including all stored data) and recreated the account in Thunderbird. Unfortunately, the same thing happens again. The recovered mails are not displayed in Thunderbird and after closing the program, the mails are deleted again in OWA and I have to recover them again. Finally I went so far as to uninstall Thunderbird completely from my computer and reinstalled the software. That did not fix the problem either.

I will also provide another observation: in the past when I have recovered individual emails the same behavior has occurred. Seems that when Outlook or Exchange places a deleted email into the recovery queue, there is a change in its identify such that TB now views it as a deleted message.

Any suggestions on how this can be fixed?

Best regards

Upgraded to the newest version of Thunderbird, 115.11.1 (64-bit) and now I can not get into my emails on bellsouth.net. . Error message "Sending of password for user xyz123@bellsouth.net did not succeed. Mail server inbound.att.net responded: [SYS/TEMP] Server error - Please try again later." I keep trying but same error for two days now. I can get my email on the web (Yahoo mail) ok. I double checked the setting and everything is good and migrated to the new version ok.

I see a preview of new emails that fades after a minute or so. I just saw such a preview, it faded, but when I opened Thunderbird, there is no new email in inbox.

How can I find it?

Also, is there a way to change frequency of retrieving new emails? To create an account for this, I had to get a 6 digit code...it took 4 minutes to appear.

I used the same password I have been using for a long time with my Verizon account and now I get this message: Sending of password for user k.machv@verizon.net did not succeed. Mail server pop.verizon.net responded: [SYS/TEMP] Server error - Please try again later. I can open and download my email messages via AOL but it will not recognize my password to allow me to download my messages to Thunderbird.

A while ago my long-time hotmail account stopped working on two computer with windows 10 and one with windows 11. Last night, I looked up an article that said I have to use Oauth2 instead of normal pw. I made that change on the windows 11 machine and a popup occurred that wanted the number from the google authenticator on my phone. I gave it that and it checks mail now just fine.

This morning I went to one of the Windows 10 machines and did exactly the same. I tried some different server names online and tried some, but after a while I started getting a little window that asked my email address and pw. I put my hotmail address in and got this message:

Microsoft Accounts or personal email addresses don’t work here. Make sure you enter your work or school account (e.g. user@contoso.com). If you want to reset a Microsoft Account password, click here.

Now this is the very same hotmail email that worked on windows 11 with the same server settings last night. It still works.

Now, on the windows 10 machine with those same settings, I get the blank extra window. The extra window appears, does not populate, and disappeared.

It is: https://login.microsoftonline.com/common/oauth2/v2.0/authorize?response_type=code&client_id=9e5f94bc-e8a4-4e73-b8be-63364c29d753&redirect_uri=https%3A%2F%2Flocalhost&scope=https%3A%2F%2Foutlook.office365.com%2FIMAP.AccessAsUser.All+https%3A%2F%2Foutlook.office365.com%2FPOP.AccessAsUser.All+https%3A%2F%2Foutlook.office365.com%2FSMTP.Send+offline_access&login_hint=redacted@hotmail.com

I had no opportunity to do what worked on the windows 11 machine just last night. I cannot check mail on hotmail on this windows 10 pc. I took all the updates available to Thunderbird and firefox. TB is 115.11.1

I'm stopped. Why would it work on one pc and not another? Oauth2 on the windows 11 asked for authenticator. On the windows 10 it never asks.

Hello,

I updated to 115.11.1 (32-bit) and unified folders will not appear and the option will not stay checked. I have exhausted my options. I previously had 64-bit with same issue so I deleted and installed 32-bit as some said this would help the issue ( I'm on 64-bit windows 10 OS).

I've tried deleting smart mailboxes, virtualfolder and jsontreefolder

nothing is working, I am at wits end. Please help!

Yahoo Mail was down for HOURS last night. When it comes back up overnight, I can login to my secondary emails (Yahoo.com) but the correct password for rshearin@verizon.net responds "server error"

Yahoo washes their hands of it because it's a "third party app."
