Thunderbird Community Forum

I'm assiting an elderly user of Thunderbird. We were trying to update his saved password but the menu items did not match my current version 153.3.1esr. When I asked him to check his version he had options to update from v52. He went through 3 update cycles to v78 when all his data had disappeared. I found some information at: https://support.mozilla.org/mk/questions/1312391 which seemed to put the issue at a file format change in v78. When he looked at the profile folders the most recent was created in 2024. (I couldn't get him to find a modified date more recently.) When he closed Thunderbird and used the Run command "Thunderbird.exe -P" we couldn't find a way to select that most recent profile folder. Are you able to give me instructions I can use in a Windows remote (quick) assist session to restore his data from the profile folder?

Alternatively, is it possible to downgrade back to v68 of Thunderbird; would this restore his data (account settings, emails, contacts/address book etc?

Thanks in advance for any guidance you may be able to offer.

Hi,

I am unable to get Thunderbird to work after my microsoft password was updated. I get the popup & enter my email & new password, but I never get the second popup to accept permissions. It just doesn’t go any further. I can see Failed login attempts for TB on the microsoft side. I am not too tech savvy, so I’m doing my best to troubleshoot!

This is Thunderbird 78.14.0 on mac 10.11, YES, that is old, it is a legacy mac! It was successfully setup with OAuth2 over 3 years ago & worked fine until the password update. I was able to add TB to an old 10.15 mac & it got the permissions popup & the account was added fine (but it is also using TB 150.0.2). Oddly, there was no 2FA prompts given, it just connected with my password only??

I had a number of devices that needed passwords updated, so I’m wondering if there was a conflict when trying to do this one? Do I need to delete certain files? I found where to delete the stored passwords & did that, but it’s not moving past that point to even store new ones & connect. I can’t grant permissions?

Also, I notice the successful TB login activity shows my IP address, whereas the unsuccessful one shows Browser Mozilla Firefox. I’m not sure if that helps with troubleshooting or not!

Thank you for your time!
