I've been using Thunderbird for over 20 years and I run it on two PC (to have a copy at home and in the office) Running 144.0.1 (32 bit) on Windows 10 and same but 64 bit on the other. The problem is with the 32 bit PC although I don't think this has anything to do with the problem.

Came back to my PC today and my inbox emails are not opening. About 88,000 emails in the inbox can't be accesses but the list of the email info are showing. Click on any one and it's blank.

I have no idea why this has happened, my only ideas are they could be connected with one of the following: 1. A windows restart and update 2. Kaspersky internet security deleting a trojan virus from an email in the inbox and deleting the whole inbox file instead - I have already asked Kaspersky support and they said it would not delete the whole file but I'm not so sure. 3. It might have lost the email when doing a 'compact folder' but I think this is unlikely.

When I closed and restarted Thunderbird any new email coming into the inbox worked perfectly but still the 88,000 previous ones were not visible/readable.

Any help would be appreciated as I'm completely stuck It's strange I only had this problem on the 32 bit version of Thunderbird? Thanks, Brian

Neither do I, but why are you still running the 32-bit version of Thunderbird anyway?

About 88,000 emails in the inbox can't be accesses but the list of the email info are showing.

Even though Kaspersky did not delete the entire Inbox file, the most likely scenario is that it did mess with it, and by doing so did corrupt it, and the corresponding .msf file. So the damage was already done. Later on Thunderbird did an attempt to fix the corruption, and as a result your Inbox messages were gone. You'd need to restore them from a recent backup created prior to the corruption.

These are some generic suggestions to avoid problems with anti-virus software.

Create an exception in your anti-virus software for the Thunderbird profile folder, so that the anti-virus real-time scanner will not scan it. https://support.mozilla.org/en-US/kb/profiles-where-thunderbird-stores-user-data#w_how-to-find-your-profile

Don't let your anti-virus software scan incoming and outgoing messages.

Don't let your anti-virus software scan attachments.

Don't let your anti-virus software intercept your secure connection to the server.

Remove any add-ons your anti-virus software may have installed in Thunderbird.

Keep it working. https://kb.mozillazine.org/Keep_it_working_-_Thunderbird

And last but not least, backup your Thunderbird profile on a regular basis. https://support.mozilla.org/kb/profiles-where-thunderbird-stores-user-data#w_backing-up-a-profile
