Thunderbird Support Forum

I just installed Thunderbird 91.8.1 and would like to migrate pst files generated by Outlook 2010.

It somewhat works - if I do "Tools --> Import --> Mail --> Next" and select Outlook, Thunderbird starts importing apparently all the pst files that are present on the PC, without allowing which ones to import to be explicitly specified.

Is there a way to specify which specific pst files are to be imported?

Good Evening, I had to reinstall Windows 10. My computer repairman installed Thunderbird along with much of my software. Since the reinstall I cannot Upgrade to Thunderbird 91.8.1. The auto update fails and the re-install does not upgrade to the new version. I have downloaded the new version many times and it still stays with the old version after the re-install. A couple times Thunderbird said I had the new version after I re-installed Thunderbird, but after restarting Thunderbird it goes back to the old (91.7.0) version.

Should I delete Thunderbird before I try to install? If I do will I loose all of my E-mail and folder information?

I would appreciate any advice. Thank you, Terry Prather [removed email from public]

Today, I am very dissapointed to report, I will be leaving Thunderbird after 20 years... Because it does not work with Microsoft Exchange Server. I am soooo dissapointed!

Hello, I've just set up Thunderbird on my IMac OS Monterey version 12.2.1 and have synchronized my gmail account. However not all folders have migrated. What is causing this and how can I fix it? Thanks!

I upgraded from Thunderbird 52 to version 91. Even though all the account settings appear to be correct, I can neither send nor receive mail. What the -- is wrong?

My windows 10 took a powder and had to have it repaired The thing that i may not be able to get are the add ons and the address book that i had on it they are installing anew hard drive but were able to back up some of the files and such. I know it is something about address book and history but not sure how to do it .i and when it comes back can i come back and get help

The situation is bad for my hard drive, not enough room to import the outlook files into TB. So is there a way of moving the destination for the import function to another drive so I can collect my eamils to use in TB?

OR

Can I somehow split the import of the emails into 2 or three attempts then save to a memory stick step by step?

I am really stuck so any help I would appreciate please!

I experienced a problem with Thunderbird suddenly not recognizing my password. Kept giving me a notice that said my password/account had been "blacklisted". I've never seen that in 20 years. I called my local internet company, Comcast.net for help. He walked me through deleting and re-installing several times before it dawned on me that Bitdefender (anti-virus software) might somehow be blocking my password. I turned off VPN and unchecked all the boxes at Bitdefender. And I could suddenly reinstall Thunderbird e-mail addresses. HOWEVER, all the folders, which I think were stored locally (on my laptop) are gone. I had lots of stuff I use on a daily basis in those folders. How do I get them back? Can I get the back? My server is IMAP but I don't know if they were stored online or on my laptop. Somebody help me, please?

Today I upgraded my TB portable standalone (no portable platform) from 60.9.1 to 68.12.1 As that what it said I could upgrade to in the about window. All worked fine. Now the about window tells me I can upgrade to 78.14. But there is no portable version portable version of that available (sorry I know Mozilla do not support the standalone version). There is a portable version of 91.6. Can I upgrade from 68.12.1 to 91.6? Thanks!

I'm using TB 91.7.0 (64-bit) on Mint Linux. I somehow deleted a folder full of messages.

I do have a backup of the entire TB folder from few days ago, but can't figure out how to restore that folder back into the main TB universe.

Everything I have found says to use https://addons.thunderbird.net/en-CA/thunderbird/addon/importexporttools/ but that apparently has been corrupted as a protest by the author.

"Apparently the add-on has been corrupted by the author. "The site and all the extensions have been made unavailable as a form of protest against the illegal fascist measures and abuses against personal rights that have been occurring in Italy (the country where I live) since March 2020."

So, can someone tell me how to restore a folder of messages back into my T-bird successfully? Thanks everyone, Barry

When I downloaded and sync Gmail to thunderbird, I encountered the following issues:

1. The number of emails on ALL MAIL folder is not the same as that in my Gmail. Thunderbird has more than 800 emails compared to my Gmail.

2. When I randomly check my emails through the search function, the emails can not be found on the location it states thy are. Ex. location=all mail , but when I search ALL mail , the email in not there.

3. SAME Email but the timestamp in Thunderbird is 1 minute less than the time stamp in the Gmail. Ex. In Gmail time stamp is 11:04 am , in thunderbird it is 11:03am

4. Also can I change the Date Pattern in Thunderbird from DD/MM/YYYY to MM/DD/YYYY?

Thank you!

Hi, I have two Win10 computers both with Thunderbird installed. Each computer has a different email account that Thunderbird controls. While they are separate accounts (i.e. different user names) the mail service (domain name) is the same. How can I move both accounts on to a new Win11 computer using Thunderbird? I've read the instructions on how to move Thunderbird from an old computer to a new computer but I wonder if I use those instructions I will overwrite one of the accounts. thanks

Hello all,

I have several machines we use thunderbird and gmail connection on.

We can only get the accounts to link if the authorizations is set to "normal password"

From what I have read on the forum, we will need to change the authentication to oAuth2 for our accounts to work after May 30th.

Following the steps to do so, and authenticating (and allowing access) in the browser, I am unable to send/receive on the thunderbird side. Switch it back to normal password and it will again work properly.

Is there anything I missed here? Not understanding why we cannot get Oauth2 to work.

Current Settings

IMAP enabled in gmail Cookies allowed in thunderbird Less secure apps off in gmail (trying to get ahead of this before May) private/public windows defender firewall off

Thank you

Came out of Win10 mail, moved to Thunderbird. (Good decision). After much screaming and kicking I managed to get my address book info out to a text file, formatted as CSV. Very simple, 3 fields: firstname,lastname,emailname@emailaddrs comma delimited.

Used the Import function, aligned 3 fields with the input data, done. It created a file called "email contacts". All of the addresses came in. Then it got kind of strange. When I open the that file it only shows 2 columns. Col1 is "NAME", Col2 is "EMAIL" Col2 is correct but Col1 shows the emailname only snipped off of the full email address. If I open any entry in the address book with the EDIT button, the first name and last name are there, so the import worked. So the question is: How do I get the top level of the address book to display the firstname, lastname? Did I do something wrong on the import? I can't seem to find any way to add columns or re-arrange the display. The "select columns to display" menu doesn't have any choice that I recognize. I can re-format the source file any way I need to, is there a better structure for import? Advise needed.

I need to install a mailbox on a new machine. I have got as far as the second screen on manual configuration, ie the one which starts with IMAP etc but I can't remember what to enter in some of the boxes. I don't know the port number (or even what that means) and on the host name for the outgoing server I think it began with relay but can't remember the rest. My ISP is refusing to help so please can you? JW

Hi, I'm struggling to access my address book from my old PC, which died.

The hard drive still works so I have been able to access the old profiles (why are there 2?) and replaced in the install of this new machine:

"Your Thunderbird profile cannot be loaded. It may be missing or inaccessible."

So.. that didn't work then. I cannot even load Thunderbird now, just gives that message.

The original machine was Windows 7. I cannot run it, so cannot tell you what version of Tbird it was but it was reasonably up to date. Current install is the very latest.

So... what to do next? I can put a copy of the profile back... OK, can start Tbird again, but how to access the old profile with many years of address book?

Manually copying the profile files into the profile folder doesn't seem to work, even after removing the (new) originals. Rather than using the old ones it's just saying it can't find the newer ones, so I presume there's some way of telling it to use those older ones?

Thanks!

I followed [guide] to move my Thunderbird profile from my old computer with Windows 10 to my new computer with Windows 11, but it is showing up as an empty window with no emails or folders/accounts. It also doesn't show my tabs/session. If I try to write a message, there is no "from" email address. I do get email notifications though, and I saw in Gmail that my forwarding filter worked as well. There is no error message or anything. I tried starting it in Troubleshoot Mode, but the same thing happens, except that the background color is different. I attached a screenshot of it in Troubleshoot Mode. Could this problem be due to Windows 11? Is there anything I can do to fix it?
