I tried using Thunderbird to check my Office 365 email, with the following settings

IMAP: outlook.office365.com Port: 143 SSL: STARTTLS

SMTP: smtp.office365.com Port: 587 SSL: STARTTLS

Normal Password

All the settings are retried by Thunderbird once I enter the IMAP and SMTP details.

However upon clicking done, there will be a message saying "Unable to log in at server. Probably wrong configuration, username or password"

I have verified the username and password is correct, and also IMAP enabled for this account, but keep getting password wrong message.

Thunderbird authentication of Gmail IMAP Account fails

I'm trying with utter lack of success to configure a Thunderbird install to link to a Gmail account via IMAP.

System Basics: Windows 10 Home, 64bit, fully patched. Antivirus by MalwareBytes 4.30 Premium, fully updated. No fancy firewall, just a regular router.

This account had been installed and working fine until a family member "helpfully" changed the Gmail password, but reauthentication fails. I enter the account details, including password, into the Thunderbird Accounts settings for the account; it pings Google and correctly retrieves all the IMAP settings, and when I click "Done" Thunderbird opens a browser window to Google's two-step authentication with the email address prepopulated. However, when I click the blue "Next" button on that authentication page, rather than advancing to a password screen, the browser simply deletes the email address from the text box and stays on the same screen (see attached image for what I'm talking about).

Things I've tried:

  • Uninstall, reboot, reinstall Thunderbird.
  • Turn off MalwareBytes protection.
  • Uninstall, delete every registry key related to Thunderbird, reboot, reinstall Thunderbird.
  • Clear cache on every browser on the system
  • Change Windows default browser settings to either Chrome (see below) or IE/Edge
  • Install new browser (Chrome wasn't yet on this PC), then change Thunderbird's file handler for https to Chrome (this is MUCH harder than it used to be as T-Bird v. 78.anything doesn't have the old "Preferences" menus)

Incidentally, changing browsers doesn't seem to make a difference in that pop-up browser window, so I suspect Thunderbird is using its own internal browser and not the system browser.

I have, and can send, the support info extract from T-bird to a support technician but am unsure of uploading it here. Nevertheless, I welcome suggestions ... this is driving me nuts!

I have just had to install thunderbird on a new PC, and the email setup system is causing serious crash errors (red boxes with lots of text and Stack Overflow programming bugs (the actual thing not the website) ). I want to try installing an older version of Thunderbird, specifically 78.13.0

And I can't. The thunderbird website only gives me the ability to download the new version 91 or nothing at all.

I can find possibly older versions of thunderbird from 3rd party websites but they look a little.... off and I don't fully trust their content,

But, Why on why can't Thunderbird offer historic downloads of previous versions for those that need them or those that want to explore if they work on our specific systems.

How do I download version 78.13 from a reliable source?

Merry Christmas Everyone. I have been using thunderbird for email with windows 7 for several years, and it does exactly what I need. One thing I definitely need is my own folders for different incoming email. No problem with windows 7 but I cannot find how to make them with windows 11 (old laptop gave up - had to buy new one). Right click on existing default folders or email name does not offer the option. All folders is ticked, as is folder pane. Hope you can help. Thanks

I have read probably 100 of your help topics and none of them seem to address my topic in plain english. I have used Thunderbird for years on a windows computer (currently windows 10, Tbird Ver 78.6.0) and I am trying to move my profile from my windows computer to a new Mac running Big Sur Ver 11.1. Thunderbird (for some unknown reason) actually created 4 different profiles on my windows machine (two under: users/alan/AppData/Local, and the same two profiles under users/alan/AppData/roaming) but I have figured out which profile that Thunderbird is using based upon the help/troubleshooting/profile folder/open folder (which happens to be one of the ones located under: users/alan/AppData/roaming) and it is 13.9GB. I copied this folder (and all included files) to a jump drive so that I could move it to my new Mac.

  I am new to Apple and know nothing about their operating system.  I downloaded Thunderbird from the Mozilla website and installed it according to their directions.  I finally found the default profile on my Mac that was created when I installed Thunderbird and I deleted it.  I copied my existing windows profile to the same location.  Now when I start Thunderbird I am greeted with a message that states: "Your Thunderbird profile cannot be loaded.  It may be missing or inaccessible."
  Obviously I have done something wrong.  Please direct me how to correct my problem -- it seems like this should be pretty simple, but I am lost.
  Thank you very much!!

I now want to copy and paste my old address book to my new profile Previous help on this forum says that my old address book is in files abook.mab and history.mab but in my old profile these files are suffixed .bak (eg: abook.mab.bak) My new profile already has a few addresses - which I am happy to lose - but does not have any .bak files. For the address book it seems to have these: abook.sqlite abook.sqlite-shm abook.sqlite-wal

history.sqlite history.sqlite-shm history.sqlite-wal

Not a .mab (or .mab.bak) file to be seen.

Can I just copy and paste abook.mab.bak and history.mab.bak?

When I drop the .dmg into the app manager I get a message "The app is currently not available in your country or region". I'm in the UK.

Is this really a regional restriction, or an error because the version is not compatible with the Mac M1 OS?

Please help!

I have been using TB for many years, but with the latest update to version 78 I cannot connect my Google contact list as the addon I used is not longer compatible. The suggestions I have read about is to use TBSync, which I have installed, but I can't get it to connect to my Google account. Each time I try autodiscover I get a message saying it has failed. I tried to manually enter the server name, but that wouldn't work either.

I can't find any support instructions in the Add In web site or on the Mozilla support site. Can anyone help?

Can I revert to an earlier version of Thunderbird?

got into a terrible mess trying to migrate messages, profile,passwords etc from Linux Mint (18) Thunderbird version 68.10 to a brand new windows 10. i have installed latest thunderbird (78) on windows.

i've tried 2 methods, one involving 2 steps on both machines, the other using 3 steps as i noticed that when i first looked at the method on linux it was for 68.10, and said 2 steps, then when i went to the windows the mozilla support had changed from 2 steps all around to 3 steps, and thats where i started to get confused, and it wasn't helped that a few times i forgot to close thunderbird. i think the mozilla support recognised i was on windows 10 and changed the steps accordingly.

so basic question is from 68.10 linux do i use ; a) 2 steps up on both machines b) 2 steps on linux then 3 on windows c) 3 steps on both, or d) should i uninstall 78.8 on windows and install 68.10 ?

My email is name@verizon.net. I am trying to switch over from windows live mail. When I set up Thunderbird account it expects the pop3 server to be .verizon.net . However aol took over the management of the servers and switched both the incoming and outgoing servers to pop.aol.com and smtp.aol.com When I go in and manually change the incoming and outgoing servers, I have successfully modified the info. However, when I go into the show password page, it shows my url as mailbox://pop.verizon.net (mailbox://pop.verizon.net) Twice I was able to set the account up and Thunderbird successfully brings in my existing emails from the aol server. However, the next time it checks for mail I receive this message – “Sending of password for user name did not succeed. Mail server pop.aol.com responded: [SYS/TEMP] Server error - Please try again later.”

It never succeeds after this.  It looks like Thunderbird is still using the pop.verizon.net address for incoming mail even though it correctly lists in the server settings the pop server as pop.aol.com.

Please help me resolve this problem.

I'm having some trouble here doing a migration from Outlook 2019. Whether in the latest version or version 31.8, Thunderbird is not finding my Outlook file. Currently, the file is in a non-standard location. Where does it need to be? Will it need to be on the C: drive (which is rather small)? Or can it be found on the D: drive?

I've looked at other means of importing. I tried exporting from Outlook into a CSV file, but Thunderbird does not see all of the columns that were exported. For instance, the email addresses were not in that second column to be paired. That's rather useless.

Another option that came up in the search of previous answers was to export to vCard. It does not appear that I have that option in Export. And individually saving hundreds of contacts as vCards is not a particularly viable option, either.

What would you suggest?

Hello

Many thanks if anyone can simply answer these 3 queries for me!

I don't need explanations etc - even just a 'yes' or a 'no' would be sufficient for me. Or just clear step-by-step guidance as to how to do something.

QUERY: 1. Should I just wait and see if this latest version of Thunderbird will download itself automatically? . . (Though I'm getting fed up with this message coming up every time I go to my emails, and wish I could find a way to shut it up!).

QUERY: 2. How can I be sure that any new version of Thunderbird won't go and alter/remove any of the current features that I like and am accustomed to?

QUERY: 3. If I found it had altered/removed features that I liked etc, could I ever get these re-instated?

MY PROBLEM When I click on 'Download Thunderbird' nothing happens, except that I'm taken to here: https://www.thunderbird.net/en-GB/ No download happens, or not any that I can see. I feel like I've been taken to a 'cul de sac' instead!

Along with this message is always 'We'll help you download it'. Er.... what 'help'?

I've been happily using Thunderbird for email for many years. Recently, the gmail OAuth2 requirement has made my POP3 accounts quit working. Currently on 38.5 for Windows 10.

Following various posts, I've tried to convert two specific email accounts to imap, and things are not going well.

My primary email is already imap and works fine. I've tried multiple times to convert the other two, and my current state is I've deleted those two accounts entirely (via Account Actions). When I try to install Existing Account, I eventually get to the point where the server config seems correct, but hitting "Done" results in the above message. I'd be surprised if imap.gmail.com can only support one email address. The emails are named differently, and use different passwords. Imap is enabled via browser based access to both accounts.

Incoming server imap.gmail.com:993 Outgoing smtp.gmail.com:465

Hi,

I have 3 GMail accounts. I am the admin and sole user on all 3. I have just installed Thunderbird for the 1st time on a PC running Windows 10 Home, and am now trying to connect my accounts (using IMAP). These accounts have been connected on this same machine through MSOutlook for months, and have been working fine. I am connecting them across 2 different user profiles on the PC. Two of them have connected without issue, one on each of the user profiles, but with the 3rd, I keep getting the "Unable to log in at server..." error. The Name/email/password are all correct. I have tried connecting my 3rd email account (+New/Existing Mail Account) as the 2nd account on both of my profiles but I get the same error on both of them.

I have verified that Thunderbird is configured to accept cookies.

Is there some issue with having 2 GMail accounts linked to the same instance of Thunderbird?? (I hope not!! - that would be a complete deal-breaker!)

Is there anything else I can try?

Many thanks

I have two Gmail accounts. Both have IMAP enabled. The first can't be set up in Thunderbird with OAuth2 -- I need to enable "less secure apps" in my Google account, and then make manual settings. The second works as expected. What could be preventing the first account from connecting to TB? I had this issue on TB 68 and also on TB 78. If I remember correctly, I had this issue both on Windows and Linux. In the problematic Gmail account, I have both IMAP and POP enabled. Do I need to disable POP?

There are a lot of questions and answers around moving Windows Thunderbird data from one computer to another, and I have tried to follow all the advice, but still running into issues. One thing to note is that my "UserName" folder is different on my new computer, and I am trying to accommodate for that difference as well.

I've tried various ways to do this, each time uninstalling TB and deleting my Thunderbird folders in my \AppData\Roaming and AppData\Local\ to start fresh, but perhaps there is some registry key messing things up??

Steps Taken: I followed "Moving Thunderbird Data To A New Computer" article and YouTube video (https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer) article, but it doesn't cover my situation with the new <UserName> folder. This is what I did:

1. Identified old Profile folder on OLDComputer. 2. Copied entire “Thunderbird” folder from OLDComputer. (Note, old <UserName> folder: “First Last”) C:\Users\First Last\AppData\Roaming\Thunderbird\Profiles\4enlv7u2.default 3. Installed Thunderbird 91.4.0 on NEWComputer. 4. Started Thunderbird. 5. Did not set up an account. 6. Closed Thunderbird. 7. Replaced the Thunderbird folder in this folder Users\First\AppData\Roaming\ with the Thunderbird folder from my OLDComputer. 8. Start Thunderbird, and get error: “The file mailbox:///C:/Users/First Last/AppData/Roaming/Thunderbird/Profiles/4enlv7u2.default/Mail/mail.blahblah.net/Inbox?number=7075&part=1.2&filename=STATEMENT.pdf&type=application/pdf cannot be found. Please check the location and try again.” 9. So, I edited profile.ini because the <UserName> path is different on this computer. • Updated “IsRelative” from 1 to 0. • Under the [Profile0] section, updated these two lines (Changed “IsRelative=” from 1 to 0), and replace the <username> in the path to just “First”:

IsRelative=0 Path=C:\Users\First\AppData\Roaming\Thunderbird\4enlv7u2.default

10. I refreshed or something, and got a dialog to Create/Rename profile. I renamed it from “default” to “First”. 11. I notice all my old email has loaded. 12. Then I restarted Thunderbird, but...

Got error: “Your Thunderbird profile cannot be loaded. It may be missing or inaccessible.” Then it wont run.

What are my next steps, or how can I re-do this properly from scratch (I'm getting good at that) THANK YOU SO MUCH IN ADVANCE!!
