I have never disliked an email program as much as I do Thunderbird!!! I thought Outlook was bad, grrr. Sorry for the rant.

Somehow today, my "send" tab in Thunderbird got reset to "send later". Not only will it not let me return to the 'send' default, copying the text of draft messages I created are all set for this too so won't let me copy and paste into a new message in Thunderbird and be able to send that! (I wish I could attach a screenshot of the tab but that function isn't available on the Thunderbird page either!)

So grateful if someone can tell me how to fix this.

(p.s. If Mozilla cares about its users as much as I've always thought it did, surely someone from the company can 'step in' and address the multitude of problems so many of us keep having without resolve? I still cannot open messages properly to read and reply after the last glitch. I'm almost ready to stop using Mozilla altogether ... and that's a BIG crossroads for me because I LOVE the Firefox browser! If anyone from Mozilla is reading this, PLEASE intervene!!! What a supreme waste of time this entire email program is!)

I changed my gmail password on a google app. gmail stopped working on Thunderbird. Tried to remove gmail acct and add existing account. Now gmail acct does not appear in the email list. Thunderbird states incoming server already exists. I can go no further with this. Please send suggestions.

Some, but not all emails are appearing incorrectly. For example, when I open one email the following info is display (instead of the email contents):

3D"0" cellpadding=3D"0" cellspacing=3D"0" class=3D"mcnFollowStacked" styl

e=3D"display: inline;border-collapse: collapse;mso-table-lspace: 0pt;mso-t= able-rspace: 0pt;-ms-text-size-adjust: 100%;-webkit-text-size-adjust: 100%

That is just a portion. I get the full/correct version when I use webmail or another email client (such as Outlook). How can I fix this?

We installed the latest version replacing an old version. My gmail accounts in thunderbird are not keeping copies of sent emails or emails sent to trash. In some cases only keeps 2 days. Is there some selection that i need to do?

I recently upgraded to version 102.0.1 (installed via snap) from version 91.9.1 (installed via apt repository) running on Kubuntu 22.04 LTS.

In version 91 I could specify "combined inbox" for my three email accounts. However, I have not been able to locate the setting for this in version 102.

Is this even avaiable?

Microsoft is enhancing security and disabling Username/Password in favor of OAuth2 authentication. While this works for the primary account, Shared Mailbox accounts will not connect with OAuth2. There is a temporary solution to re-enable the legacy authentication, but this too will be disabled in September, 2022 (according to MS Support).

On June 23rd all the sudden my oldest inbox message was that day at 2:04 pm. All prior emails were gone. I then noticed several folders and subfolders under that inbox were also gone. Subsequently I opened Outlook and did a synch, and all of my lost inbox emails repopulated from that synch. I also noticed that, while it appeared to be synching the lost folders, they still have not popped back in to Thunderbird on my Desktop (although they are still present and never left Thunderbird on my iphone). I desperately need those folders as they are for current and recent past real estate transactions. I also tried to follow some Google advice and got to the place where it talked about hidden folders, and unchecked that so that they supposedly would no longer be hidden, but they still are not on my desktop. Perhaps I Googled old instructions? My Help, about, says I have 91.11.0 (32bit). Any helpful advice? Pam Reilly sdhomesbypam@gmail.com

CHALLENGE #1 There are LOCAL FOLDERS that continually populate even thought I have previously deleted them. How can they be removed permanently?

CHALLENGE #2 When I move folders under ARCHIVES, why does it continue to appear under LOCAL FOLDERS?

HELP PLEASE :-) Thanks in advance!

After upgrading on my Mac Pro 2010 to Thunderbird 91.10 I couldn't access my Google account. I found some suggestions (e.g. change to 0auth) - and eventually am able to receive e-mails. I still can't send them - not even when I went back to 91.4 (when I could send e-mails). I am being asked the password for my Google account, but when I fill in the correct one, I am again asked for my password - etc. I use the correct one as evidenced by the fact that I can access my Google account via Safari. I have contacted Google One. I followed their suggestion to accept Thunderbird on my Google account. I still can't send e-mails. Google One just now suggested that I no longer use Thunderbird as it does not seem to satisfy their safety standards. I don't want to do that (I like the lay-out). The alternative is to cancel my Google account. Please help: what is wrong - or if I am to blame, what am I doing incorrectly?

I have been successfully using Thunderbird with O365 and OAuth2 since my organization reconfigured for 2FA back in April 2022. Each time I need to reset/change my enterprise e-mail password I must reset my OAuth login, which I did successfully once before by simply deleting saved logins and then re-completing the 2FA process.

After doing that again last week I can no longer send e-mail from TB 91.11.0 -- it successfully connects to smtp.office365.com and then hangs indefinitely on "Sending message...". IMAP is functioning normally (receiving e-mails, moving messages between server folders, etc.). I first confirmed that my (well-documented) my working SMTP settings were not changed.

What I have done to research the issue:

1. confirmed that security.enterprise_roots.enabled = true (and all org-specific certs are shown) and I have turned up these Iog levels to 'All': mailnews.oauth.loglevel, mailnews.send.loglevel, mailnews.smtp.loglevel
2. in preferences, confirmed that cookies are accepted from: https://login.microsoftonline.com, https://outlook.office365.com

The error console shows that my TB receives a successful response from the authorization server with a access token (and is refreshing on intervals afterward). When I send a message, the console reports successfully connecting to smtp.office365.com and then simply waits forever without any apparent timeout. When I cancel sending the message, the console reports the socket to the SMTP server is closed. No further detailed information is emitted into the console. I need help with diagnosing the problem further to understand why no progress is made.

I have also tried the following to fix and also re-confirm this issue:

1. created a full backup of my profile folder
2. deleted any passwords and/or OAuth2 authentication tokens Thunderbird has remembered for the troubled account
3. deleted any O365 related cookies
4. deleted the subject account
5. restarted Thunderbird
6. re-created the subject account using manual account setup, and specifically for SMTP: smtp.office365.com:587 with STARTTLS and OAuth2, user name in format 'first.last@domain.gov'.

It was working before. After resetting my password and completing the 2FA process, sending e-mail simply stopped working and I am not sure how to proceed.

Any suggestions for other settings to check as well as how to get TB to emit more detail in the console would be greatly appreciated.

Thanks, Jason

When I use thunderbird 102 on Linux, the view state doesn't save between loads. For instance, if I turn off the message preview pane, it stays off as long as thunderbird is open. However, when I quit and relaunch, it and other view changes (filter bar, etc) are reverted.

After a recent Thunderbird update, I no longer see my address book from Gmail. Its still there on gmail, but doesn't get loaded into Thunderbird anymore. I only have a few new addresses I used and it saved. How do I get access to the full Gmail contacts / address book again?

This is a Gmail IMAP install Right now I cannot compact many larger directories (Inbox, sent, etc) because there is not enough disk space.

I reduced the number if folders that are synchronized and the age that messages are synchronized (via account settings) but this doesn't seem to have effected the install size. Is there a way to force Thunderbird to reconcile the files in a given directory with the synchronization settings?

Any other ways to reduce the thunderbird disk usage?

I am updating thunderbird for my gmail account logins for several machines. In security settings, I changed the authentication method from normal password to 0auth2 for incoming and outgoing servers. Upon initial login by thunderbird to gmail after the changed setting, gmail sends a verification window which requests your user name, password and authorization for gmail to allow thunderbird access to my gmail account. The windows 11, 10 and windows 7 (yes don't laugh) machines allowed for smooth verification. My windows ViSTA machine provided a gmail window for verification but it arrives blank - there are no written words or fields to fill out with my username, password or authorization - I am aware about "non support" for older operating systems but there must be a way to obtain data on the verification screen - windows 7 machines worked ok - what may be the solution for the Vista machine (a gateway desktop with who knows what chip that was the cat's meow back then). Don't want to trash the machine. All was OK until June 1st gmail compliance procedures. Thanks all.

I'm using Windows 10 and Thunderbird 91.11.0. Every email attachment forces me to save it instead of just opening it. It does not matter whether I click the file name or choose "open" from the menu on the right. There are a number of files that I receive that I don't need to save to my computer, I just need to see and approve, but in the last few months it will not let me do that. Help, please?

Recently tried upgrading from 91.x.x -> 102.x.x. Everything seems to go fine, with one critical show-stopping problem -- any attempt to connect to outlook.office365.com fails. Completely.

Under 91.x.x, I use POP as server type, server name is outlook.office365/com, SSL/TLS, and OAuth2 for connection and authentication security, respectively. Set up this way, port defaults to 995. Works *perfectly* under 91.x.x.

But, using the *exact* same setting under TBird 102, absolutely refuses to connect. At all.

Any suggestions as to what to look for?
