Thunderbird Support Forum

I have spent the last two days trying to re-establish receiving/sending emails on my Apple MacBook Pro using Thunderbird without success. This problem developed suddenly about 3 or 4 days ago and only affects the MacBook, not any other device (I have an iMac and two iPads). I have gone through the instructions in Thunderbird's support pages and those in Mozilla with no success.

How do I fix this please? Would the easiest way be to simply delete the account xxxxxxx.gmail.com from Thunderbird on my MacBook and re-instate it by adding it back in?

All the setting for IMAP and SMTP are correct and the username/password is identical on all my devices.

After update to Thunderbird 91.7.0, I cannot send emails, receive error

The message could not be sent using Outgoing server (SMTP) smtp.windstream.net for an unknown reason.

And, I had other Outgoing server setups and they are now gone.

Is there a bug intoduced with this update?

I'm new to thunderbird and, when I first added my aol mail account as IMAP, I deleted (thru thunderbird) what I thought were random, extra folders that appeared under all the other standard thunderbird folders - these were not folders I created, but rather ones I assume aol added for every account. All were removed from the aol mail site save an "Archive" folder which does not allow me to delete it even though it is under the folders section.

I didn't think anything of it at the time, but now, a "Draft" and an "Archive" folder are spawning in the trash section for my aol mail account on thunderbird and I cannot for the life of me get it to stop/move them/etc. These are not the standard "Drafts" and "Archives" folders of thunderbird fyi, but aol's Drafts section (the one on the server has an s even though the folder in thunderbird does not) and Archive folder (which I mentioned above). If I save anything to the standard thunderbird folders, a "Drafts" and "Archives" folder appear in the folder section in aol mail.

I have my settings set to use the standard thunderbird folders, but the ones from aol keep spawning in the trash every restart no matter what I try. I know it's just copying things over or whatever and I don't mind the folders appearing, but how the hell do I get them out of the trash?? I've gone so far as to completely uninstall (including the appdata folder) and reinstall thunderbird, but that didn't change anything. Are there some other settings or something somewhere that I missed? They're not appearing in the trash on the aol mail site, so I'm assuming this is something wrong on thunderbird's end and is messed up because I deleting those original folders. Is there any way to fix this?

As of a couple of days ago, Thunderbird will no longer allow me to send emails to more than one recipient. The email just stalls out on "sending" if there is more than one name/address. Doesn't matter if the additional names are in "to," "cc," or "bcc" fields. I've tried finding other reports of this online but no luck. I've rebooted Thunderbird several times. Version is 97.1.0. Please help - thank you!

I am trying to create a subfolder in one of my existing email subfolders; whatever name I try to give it, it doesn't work. If I name the subfolder "test" it works. If I try to then rename the subfolder to the name I want to give it ("accelerator program"), it gives an error message that it cannot be renamed ... I find this all very weird. I have many folders and sub folders already to organize my mails, and this has worked for many years and now it suddenly doesn't work to make a new one ... any suggestions ? Is there a limit on the total number of (sub) folders one can create in Thunderbird ? Many thanks for your suggestions or advice.

The use of a separate filter set for each Thunderbird account can be a major pain for some users. I have 32 email accounts (some of them disposable) in a number of domains for a large number of purposes. Sometimes several accounts need the same filter, so when I add a filter I add it to the dominant account, and then have to copy that filter set to the other 31 accounts. I suggest adding an option that would use the same filter set (the one for the dominant account makes the most sense) to be used for every account, eliminating the need to copy filters.

Getting a popup now every time Thunderbird tries to sign into gmail. It says "Sign in with your Google Account" but nothing works when I put in my id or email. There's no response. T-bird is set up properly and uses oauth2; this just began happening. Less secure apps is on but that's being stopped, so looks like I won't be able to use gmail anymore.

I tried deleting my gmail a/c and now I can't create one. I can't get past that "credentials needed" popup.

How can I get T-bird to work with gmail?

When I reply to an e-mail using Thunderbird, quoted text appears (in Thunderbird) with a quote bar on the left as expected.

However, when the recipient gets the message in Outlook or GMail, the quote bars are missing. In GMail quoted text is indented and a slightly different color (though it's hard to see the difference). In Outlook the quoted text is just indented.

How do I get Thunderbird to include quote bars for quoted text in the sent message?

If I format the message (with quote bars) using markdown in a browser, and then cut/paste the formatted message into Thunderbird, then it appears as expected to recipients using Outlook and GMail. But that's a painful way to compose replies to Outlook and GMail users (IOW everybody I reply to).

When I try to read Inbox emails, they open in Write mode. I have checked Account Settings> Copies & Folders, and it shows "keep draft messages in:" Drafts folder for the account. If I copy the emails to the Local Folders Inbox, they open in read mode, not write mode. How do I get the Inbox to not think it holds drafts?

When I open my email, then go to my Bulk Mail folder sometimes I get a message "Server IMAP.mail Yahoo Mail.com has disconnected. Server may have gone down, or maybe a network problem. I mentioned this to a Rogers tech and he said it is not their problem - probably a software/programme problem. Any ideas?

I have received notices from Google for all of my Gmail accounts that I have on Thunderbird that beginning in May 2022, an id and password will no longer be supported for "certain" apps. I am not sure if this includes Thunderbird - both for email and for calendar? Does it include Thunderbird and what must be done on Thunderbird to continue receiving email and calendar updates?

I keep getting a pop-up box, when I log into Thunderbird, saying T'bird needs to compact my files and asking me to check a box allowing automatic compacting. I am super careful these days and before agreeing to this wanted to check that it is genuine and not some elaborate fishing scam. Thanks, Dave

Please HELP About a week ago Thunderbird stopped connecting to imap.gmai.com and have authentication failures. I have spent days reading and trying the fixes but still no joy. Please help I'm at my wits end. Reagards

Yesterday my gmail account suddenly stopped downloading and sending emails on Thunderbird 91.8.1. I receive/send other email accounts on TB no problem. In preferences cookies are allowed and the authentication OAuth2 is set for outgoing smtp. I haven't changed the gmail password. My husband's gmails are downloading to my TB, it's only my gmail account that has stopped working. When I try to send an email I get this error message Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) smtp.gmail.com. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'. Any help would be appreciated. Thanks

Most of my emails suddenly got erased from the server (I checked in cpanel). Thankfully i took backup few days back, and thunderbird still has them saved offline (Not POP3, its still IMAP configured). I recovered most of emails but those are visible only on my system. How can i put back those emails back into server, so it can be accessed from other devices as well?

In the email client I have just come from the Unread folder contains all unread messages irrespective of the folder they might be in. The Unread filter in Thunderbird appears to relate only to the highlighted folder. I have many folders, the list being long not all are visible on the 'home' view. This means that messages in folders far down the list are only visible if I scroll down looking for them. Is there a way to modify the Unread filter to ensure that all folders are searched for unread messages and displayed together? I am using TB 91.8.1.

Recently, and not for the first time, Thunderbird sent an automatic reply which thankfully bounced. However I couldn't find the offending email when searching for this address. Using a third party tool, namely Agent Ransack aka FileLocator Lite, I found the folder and hence the email.

How can I do this within Thunderbird. I can only select To, From, Cc and/or Bcc. Not Reply-To.

Can anyone let me know if this is possible, if so how?

I am having difficult connecting to mailboxes in Plesk Obsidian on a VPS. I can set up the mailboxes in Plesk and make a note of the password. I then go into TB and start the 'Add Mail Account' process. All goes well at first. I get a green message saying 'Configuration found by trying common server names' (automatic connection). When I click 'Done' TB whirrs for a bit and then comes back with a green message showing a tick and 'Checking Password' but an orange message saying 'Unable to log in at server. Probably wrong configuration, username or password'. If I try manual configuration I get a similar sequence (using ports 995 and 465, SSL/TLS and 'Normal password').

I do not have this problem when working with cPanel (on a different server, but very similar mailboxes and security settings). This suggests to me that there's something amiss in my Plesk settings, but what could it be?

I have searched around without success. Most articles that might help are for TB 31 (even the Plesk Obsidian on-line manual). Any suggestions, please?

I have recently moved from Outlook to Thunderbird as Outlook developed a problem communicating with my Virgin Media email accounts. I am slowly finding my way around Thunderbird, but am experiencing a problem with some of my sub folders. This only applies to Virgin Media accounts.

I have looked at previous questions on a similar topic and have tried the simpler solutions (the ones applying to advanced users are Greek to me)! Unfortunately, they haven't solved my problem.

If I go to account settings and uncheck the "show only subscribed folders" box, the greyed out sub folder disappear. However, right-clicking on the folder heading and selecting subscribe and attempting to subscribe to the folders there, doesn't work.

Is there a simple process I can go through to access these sub folders?
