Thunderbird Support Forum

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.

I am trying to setup an Outlook account on Thunderbird and I get an error: "Unable to log in at server. Probably wrong configuration, username or password." I have an existing Outlook account which I am able to use on the Outlook app on Windows, the Android app and the web version on outlook.live.com I wish to have an e-mail client on my Linux Mint machine from which I can access my Outlook e-mails. To do so, I went to the 'Account Setup' page on Thunderbird and used these to set up my account: Your Full Name: <My Name> Email address: <email-id>@outlook.com Password: <My Microsoft password which I use to sign in to Outlook> Under Manual configuration: INCOMING SERVER Protocol: IMAP Hostname: outlook.office365.com Port: 993 Connection Security: SSL/TLS Authentication method: OAuth2 Username: <email-id>@outlook.com OUTGOING SERVER Hostname: smtp.office365.com Port: 587 Connection security: STARTTLS Authentication method: OAuth2 Username: <email-id>@outlook.com

I am sure that the password I am using is indeed the correct password. I still get an error as shown in the screenshot on the Account Setup tab. How do I resolve this issue? Thanks a lot!

I was finally forced to upgrade from win7 (which worked) to win 10 (me no likey) because of a required program which would not even install on win7. After the upgrade, which obliterated my hard drive of several important things, I am reinstalling TB. I always used an NAS directory for Thunderbird, and have email records going back nearly twenty years. I installed TB 115 and have tried several ways to get it to recognize my profile directory on the NAS to no avail. I tried copying data into the default directory the 115 install is looking at. The about:profiles shows it is looking in the correct directory, it produces a parent.lock file in that directory when I run the program. It does not give me my email, or contacts. I do not use the calendar or to-do lists.

My system is an AMD K6-6400K with 16 GB and a 500 GB drive. Though programs are loaded on the drive ALL data is stored in an NAS. There is about 375 GB available on the C drive.

I have used the cmd line to pull up profile manager, added a profile, pointed it to the data that is on the NAS, a parent lock file is created there too but it shows me no mail.

I have edited the profiles.ini file manually to have the program look at the directories, both the NAS and a local directory which has had the old files entered. Neither worked.

I tried opening TB and creating a new profile and pre-loading the info there, nothing. I've been at this for days now. I have uninstalled and removed manually all TB folders and reinstalled older versions to give that a go but without effect. I am no Luddite (Many years ago I owned a system integration, assembly and install company doing networking for the military as a civilian contractor.) but someone has to explain this to me like I am a five year old. There is no reason having my email back should be this difficult!

PLEASE give me a hand?

My TB directory appears in C:\Users\owner\AppData\Roaming\Thunderbird My old data folder was on a network drive at M:\Users\owner\AppData\Roaming\Thunderbird\profiles\k5zbs5az.default When I manually enter the M: address in the profiles.ini file, it "corrects" it to C:\Users\owner\AppData\Roaming\Thunderbird\ even though the switch 'relative' is off.

[Profile1] Name=default IsRelative=1 Path=Profiles/zpfeu8eu.default Default=1

[Profile0] Name=default-beta IsRelative=0 Path=C:\Users\owner\AppData\Roaming\Thunderbird

[General] StartWithLastProfile=0 Version=2

[Install5D388C1349709B37] Default=C:\Users\owner\AppData\Roaming\Thunderbird Locked=1

Running the Mozilla application with a specific profile using command line arguments brings up the program but no mail. It creates a lock file in the correct directory, but no joy.

I get no pop up error messages.

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

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.
