Thunderbird Support Forum

I’m running Windows 10 on a desktop. Thunderbird upgraded my program to 115.3.1 (32-bit) When it runs now it shows all of my old folders and the address book entries are there and incoming email notifications briefly pop up, but when I click on the popup, nothing happens. But all of the folders are empty. I experience the same thing on another PC. Any suggestions? I’ve seen this question on this forum before, but I have not see a suggested solution that works for me. Thanks for y’all’s consideration.

After the automatic upgrade to 115.2.2, I have lost access to all my folders, emails and calendar entries. But I can still see my addresses by using Tools/Address Book, and my filters by using Tools/Message Filters.

When I started Thunderbird for the first time on 115.2.2 I got to the usual message page which had all the tabs of the "open" emails I had when I last closed Thunderbird. But there was no sign of my folders and I couldn't get to any other messages (See first screenshot). I also had a second occurrence of Thunderbird running (I could have hit the icon a second time) that didn't show the tabs I had on the first screen. (No screen shot)

On a previous post here https://support.mozilla.org/en-US/questions/1424153 it was suggested that I try Troubleshoot mode. That made no difference and at that time I had no folders showing, and just two tabs. I suspect after that I deleted the tabs.

Now I get a completely blank page in what is usually the message/folder area. Also the button for the address book above the message pane has now gone disappeared (Second screen shot), and I can find no way of accessing my previous (10years+ of messages).

It looks to me as if something is wrong in the profile.

Where do I go from here?

... and the only way to restore them is to delete the folderCache.json, session.json, xulstore.json files from my profile directory. But each time I shut down Thunderbird and restart it, the same problem returns and I have to start over.

As this causes Thunderbird to lose all customizations to folder display, column displays, color badges, etc, and requires Thunderbird to download all message headers in my 6 email accounts, it's wasting a ton of my time.

All the accounts are still intact and it even says it's downloading email for each inbox on startup, I just can't see any of it because there's no folders displayed on the left side-bar.

And mind you, this was just a "upgrade"... when I tried to migrate my default profile to another computer (new workstation) it wouldn't load the proper profile without doing the -p flag on the executable and then after, has this same problem where it first displays proper accounts/folders but then on restart loses it all.

Luckily I found another users post online about deleting those internal cache/config files (for a completely unrelated problem with an older version of tbird) or I'd have been completely stuck.

Anyone have any suggestions on migrating BACK to the previous most stable build of pre "Supernova"? This thing isn't fully baked IMO.

And also, is there a better way to submit massive errors like this to the developers?

Thanks...

I'm transferring to a new computer and have installed 115 for the first time

I can successfully transfer my profile over - and on the first run, my imap emails (outlook) are present and correct. However, when I close the app and restart it, they've all disappeared. The account is still there but all the emails have gone. (Inbox, outbox, drafts, deleted, etc... all gone)

Taking a look in my profile folder, the drastic size reduction of the files contained in the imap-mail.outlook.com folder suggests that they have been erased.

I've tried numerous times and the same thing always happens.

Local Folders are unaffected.

I have not yet given 115 permission to access internet (but I don't see why that would cause what I am experiencing.)

EDIT: Having viewed another question on here (from someone with the same issue,) it seems that the messages are not being erased and can be restored if I delete the folderCache.json, session.json, xulstore.json files every time before starting Thunderbird. It's still a significant issue.
