Upgraded to Thunderbird 115: Calendar, contacts, and certs okay, but missing thousands of emails.

Hello all,

One of our users' Thunderbird installations was recently updated from version 102.2.2 to 115.0.1.

At work, we use an offline network. We have no direct internet connection at all. We use a Microsoft Exchange mail server to handle inbound and outbound emails.

When our user got a new computer last week and first signed in to Thunderbird, her folder structure was correct, but something went wrong because her inbox and sent folders were completely empty. She would get a notification whenever someone sent her an email, but when she clicked on it, it would just show her an empty Thunderbird inbox (she should have thousands of messages).

I, and others, have verified her email server settings are correct and the same as on other systems not experiencing this issue.

Her calendar events, contacts, and email certificates are all where they should be. It's just her messages that are missing.

Now here's where it gets weirder. Having created a backup of her original Thunderbird profiles directory and profiles.ini file, I exited Thunderbird and removed those profile files/folder from her "C:\Users\<username>\AppData\Roaming\Thunderbird" directory. Upon restarting Thunderbird, it asked for her to log in. She used the address and username I verified were in the Exchange server, and upon signing in, her mail client synced all her messages correctly. However, as expected, her calendar and certificate info was still missing since those don't come from the Exchange server. So, when I close Thunderbird and put her original profiles back into the AppData\Roaming directory (adding, not replacing the new ones since that also doesn't work) and start Thunderbird, we're back at square one where she's got certificates, calendar events, and addresses, but no emails in the inbox or sent folders.

Has anyone seen this before?

P.S.: Sorry there are no photos. I can't post screenshots from any of our computers.

re :One of our users' Thunderbird installations was recently updated from version 102.2.2 to 115.0.1.

Currently Thunderbird is not auto updating from 102.13.1 to Supernova 115.1.0 If you were using 102 eg: 102.13.1 thunderbird will auto update to 102.14.0 Version 115.1.0 release is only available as a separate new download and installation - not as an update. https://www.thunderbird.net/en-US/thunderbird/115.1.0/releasenotes/

If the user got a message to update to 115.1.0 then that computer is using a Software updater program which detected something new available on Thunderbird new download website. It was not thunderbird informing of update. User would have had to perform the download and installation. Please make other 'users' aware of this as I have discovered people are generally not aware of this nor do they check the download release notes before choosing to download and install.

On computer: Exit Thunderbird. Access Firewall and make sure Thunderbird is set up as an allowed program.

Using original profile where mail accounts/emails are missing but calendar etc are visible: Have you tried:

  • In Folder Pane - right click on mail account folder name and select 'Subscribe'
  • Click on 'Refresh'
  • Select every folder in list and click on 'Subscribe'
  • click on OK

Then select 'Inbox' to see if it synchronises with server.

Check the settings are not filtering anything:

  • 'View' > 'Folders' > 'All'
  • 'View' > 'Threads' > 'All'

Check 'Quick Filter Bar' does not have anything selected - in the new supernova - quick filter items now display a blue strip of colour if they are enabled. Do not rely on the greyish background colour.

Alternative: In Account Settings, remove the mail account Exit Thunderbird and Allow a few moments for background processes to complete. Start Thunderbird. As it has no mail accounts it should ask to create new account. Create account.
