r/Thunderbird

I have a problem that keeps coming back at semi-long intervals where the older of my two Outlook accounts (never happened with the other one) spits out a "Command Error 12" when I open Thunderbird, deletes its entire message cache and redownloads it from scratch. Eventually I just delete the account and re-add it, which seems to fix it, but after a few weeks it happens again. And now in its latest iteration it won't even display any folders besides the inbox. And I should add, both accounts have the same server and port settings.

I'm running Thunderbird 140.9.1esr on Windows 11. What should I do?

I have several hotmail and gmail accounts in Thunderbird.. For some reason all my folders and messages from one of the hotmail accounts are gone all other accounts are fine and the hotmail account is fine when I go to outlook.com... What happened?

Mozilla Community is working day in and out to make sure that their application can support Exchange Server accounts, and that's great to see 👍. But on the other hand, the Microsoft team needs to ensure that they can’t.

As not only will this lead to a decrease in business, it will revolutionize the whole professional email industry. The email ecosystem for free usage will increase 📩, but the point of thought still is—what will businesses use? An open-source application for professional use?

Will companies be able to establish that kind of trust? After all, Thunderbird is known for its crashes ⚠️.

Let’s see what happens 🤷‍♂️.

the only way i can see the attachments line at the bottom is by double clicking on the email and opening it into a new tab. that attachments line doesn't show from the main window any more. it totally disappeared. has anyone had this happen?
